The Causes Of Life's History [cannot] Resolve The Riddle Of Life's Meaning.

We Can Now Determine, Easily And Relatively Cheaply, The Detailed Chemical Architecture Of Genes ; And We Can Trace The Products Of These Genes ( Enzymes And Proteins ) As They Influence The Course Of Embryology . In So Doing We Have Made The Astounding Discovery That All Complex Animal Phyla - Arthropods And Vertebrates In Particular - Have Retained, Despite Their Half-billion Years Of Evolutionary Independence, An Extensive Set Of Common Genetic Blueprints For Building Bodies.

The Theory Of Punctuated Equilibrium, Proposed By Niles Eldredge And Myself, Is Not, As So Often Misunderstood, A Radical Claim For Truly Sudden Change, But A Recognition That Ordinary Processes Of Speciation, Properly Conceived As Glacially Slow By The Standard Of Our Own Life-span, Do Not Resolve Into Geological Time As Long Sequences Of Insensibly Graded Intermediates (the Traditional, Or Gradualistic, View), But As Geologically "sudden" Origins At Single Bedding Planes.

If We Choose A Weak And Foolish Speculation As A Primary Textbook Illustration (falsely Assuming That The Tale Possesses A Weight Of History And A Sanction Of Evidence), Then We Are In For Trouble - As Critics Properly Nail The Particular Weakness, And Then Assume That The Whole Theory Must Be In Danger If Supporters Choose Such A Fatuous Case As A Primary Illustration.

I Love To Read The Dedications Of Old Books Written In Monarchies For They Invariably Honor Some (usually Insignificant) Knight Or Duke With Fulsome Words Of Sycophantic Insincerity, Praising Him As The Light Of The Universe (in Hopes, No Doubt, For A Few Ducats To Support Future Work); This Old Practice Makes Me Feel Like Such An Honest And Upright Man, By Comparison, When I Put A Positive Spin, Perhaps Ever So Slightly Exaggerated, On A Grant Proposal.

Throughout His Last Half-dozen Books, For Example, Arthur Koestler Has Been Conducting A Campaign Against His Own Misunderstanding Of Darwinism. He Hopes To Find Some Ordering Force, Constraining Evolution To Certain Directions And Overriding The Influence Of Natural Selection. [...] Darwinism Is Not The Theory Of Capricious Change That Koestler Imagines. Random Variation May Be The Raw Material Of Change, But Natural Selection Builds Good Design By Rejecting Most Variants While Accepting And Accumulating The Few That Improve Adaptation To Local Environments.

We Build Our Personalities Laboriously And Through Many Years, And We Cannot Order Fundamental Changes Just Because We Might Value Their Utility; No Button Reading "positive Attitude" Protrudes From Our Hearts, And No Finger Can Coerce Positivity Into Immediate Action By A Single And Painless Pressing.

Asian Homo Erectus Died Without Issue And Does Not Enter Our Immediate Ancestry (for We Evolved From African Populations); Neanderthal People Were Collateral Cousins, Perhaps Already Living In Europe While We Emerged In Africa... In Other Words, We Are An Improbable And Fragile Entity, Fortunately Successful After Precarious Beginnings As A Small Population In Africa, Not The Predictable End Result Of A Global Tendency. We Are A Thing, An Item Of History, Not An Embodiment Of General Principles.

I Emphatically Do Not Assert The General 'truth' Of This Philosophy Of Punctuational Change. Any Attempt To Support The Exclusive Validity Of Such A Grandiose Notion Would Border On The Nonsensical.

All Interesting Issues In Natural History Are Questions Of Relative Frequency, Not Single Examples. Everything Happens Once Amidst The Richness Of Nature. But When An Unanticipated Phenomenon Occurs Again And Again—finally Turning Into An Expectation—then Theories Are Overturned.

The Spandrels Of San Marco And The Panglossian Paradigm.

Wind Back The Tape Of Life To The Early Days Of The Burgess Shale; Let It Play Again From An Identical Starting Point, And The Chance Becomes Vanishingly Small That Anything Like Human Intelligence Would Grace The Replay.

The More Important The Subject And The Closer It Cuts To The Bone Of Our Hopes And Needs, The More We Are Likely To Err In Establishing A Framework For Analysis.

Science Is Not 'organized Common Sense'; At Its Most Exciting, It Reformulates Our View Of The World By Imposing Powerful Theories Against The Ancient, Anthropocentric Prejudices That We Call Intuition.

I Would Rather Label The Whole Enterprise Of Setting A Biological Value Upon Groups For What It Is: Irrelevant, Intellectually Unsound, And Highly Injurious.

Words Change Their Meanings, Just As Organisms Evolve. We Would Impose An Enormous Burden On Our Economy If We Insisted On Payment In Cattle Every Time We Identified A Bonus As A Pecuniary Advantage (from The Latin Pecus , Or Cattle, A Verbal Fossil From A Former Commercial Reality).

The Intricate And Different Life Cycles Of Both Male And Female Root-heads, And The Great Behavioral Sophistication Shown By The Female In Reconfiguring A Host Crab As A Support System, All Underscore The Myopia Of Our Conventional Wisdom In Regarding Rhizocephalans As Degenerate Parasites Because The Adult Anatomy Of Internal Roots And External Sac Seem So Simple.

What An Odd Time To Be A Fundamentalist About Adaptation And Natural Selection - When Each Major Subdiscipline Of Evolutionary Biology Has Been Discovering Other Mechanisms As Adjuncts To Selection's Centrality.

South America Had Been An Island Continent, Far Bigger And Far More Diverse Than Australia, For Tens Of Millions Of Years Before The Isthmus Of Panama Rose Just A Couple Of Million Years Ago. The Resulting Flood Of North American Mammals Across The New Land Bridge Corresponds In Time With The Decimation Of The Native South American Fauna. In Fact, Most Large Mammals Generally Considered Distinctly South American... Are All Recent Migrants From North America.

Natural Selection Is Just Three Factors - Over-production, Variation, And Inheritance Combined To Produce Adaptation To Changing Local Environments. It's Not A Principle Or Progress; It's Just A Principle Of Local Adaptation. You Don't Make Better Creatures In Any Cosmic Sense; You Make Creatures That Are Better Suited To The Changing Climates Of Their Local Habitats.

Goethe Died In 1832. As You Know, Goethe Was Very Active In Science. In Fact, He Did Some Very Good Scientific Work In Plant Morphology And Mineralogy. But He Was Quite Bitter At The Way In Which Many Scientists Refused To Grant Him A Hearing Because He Was A Poet And Therefore, They Felt, He Couldn't Be Serious.

Odd Arrangements And Funny Solutions Are The Proof Of Evolution - Paths That A Sensible God Would Never Tread But That A Natural Process, Constrained By History, Follows Perforce.

No One Supposed That Dinoflagellates Might Actively Kill Fish As An Evolved Response For Their Own Specific Advantage, Including A Potential Nutritional Benefit For The Algal Cells. And Yet The Dinoflagellates Do Seem To Be Killing And Eating Fishes In A Manner Suggesting Active Evolution For This Most Peculiar Reversal.

Facts Do Not 'speak For Themselves'; They Are Read In The Light Of Theory.

The History Of Life Is More Adequately Represented By A Picture Of 'punctuated Equilibria' Than By The Notion Of Phyletic Gradualism. The History Of Evolution Is Not One Of Stately Unfolding, But A Story Of Homeostatic Equilibria, Disturbed Only 'rarely' (i.e. Rather Often In The Fullness Of Time) By Rapid And Episodic Events Of Speciation.

History Of Life

The Oppressive Weight Of Disaster And Tragedy In Our Lives Does Not Arise From A High Percentage Of Evil Among The Summed Total Of All Acts, But From The Extraordinary Power Of Exceedingly Rare Incidents Of Depravity To Inflict Catastrophic Damage, Especially In Our Technological Age When Airplanes Can Become Powerful Bombs. (an Even More Evil Man, Armed Only With A Longbow, Could Not Have Wreaked Such Havoc At The Battle Of Agincourt In 1415.)

Precise Adaptation, With Each Part Finely Honed To Perform A Definite Function In An Optimal Way, Can Only Lead To Blind Alleys, Dead Ends, And Extinction.

A Rare Book At Once Of Great Importance And Wonderful To Read.... Gould Presents A Fascinating Historical Study Of Scientific Racism, Tracing It Through Monogeny And Polygeny, Phrenology , Recapitulation, And Hereditarian Iq Theory. He Stops At Each Point To Illustrate Both The Logical Inconsistencies Of The Theories And The Prejudicially Motivated, Albeit Unintentional, Misuse Of Data In Each Case.... A Major Addition To The Scientific Literature.

If Any Issue Should Unite Liberals And Conservatives, Anyone Who Cares About The Integrity Of Human Achievement Or Respect For Human Accomplishment, May We Not All Pledge To Avoid The Silly Censoring That Can Lead To A Codification Of Orwell's Newspeak? Consider John Milton's Reasons For Why Good Arguments Are Often Lost: 'for Want Of Words, No Doubt, Or Lack Of Breath!'

Science Simply Cannot Adjudicate The Issue Of God's Possible Superintendence Of Nature.

The World, Unfortunately, Rarely Matches Our Hopes And Consistently Refuses To Behave In A Reasonable Manner.

Some Beliefs May Be Subject To Such Instant, Brutal And Unambiguous Rejection. For Example: No Left-coiling Periwinkle Has Ever Been Found Among Millions Of Snails Examined. If I Happen To Find One During My Walk On Nobska Beach Tomorrow Morning, A Century Of Well Nurtured Negative Evidence Will Collapse In An Instant.

Humans Arose ... As A Fortuitous And Contingent Outcome Of Thousands Of Linked Events, Any One Of Which Could Have Occurred Differently And Sent History On An Alternative Pathway That Would Not Have Led To Consciousness.

We Live In A Profoundly Nonintellectual Culture, Made All The Worse By A Passive Hedonism Abetted By The Spread Of Wealth And Its Dissipation Into Countless Electronic Devices That Impart The Latest In Entertainment And Supposed Information - All In Short (and Loud) Doses Of "easy Listening".

In What I Like To Call The Great Asymmetry, Every Spectacular Incident Of Evil Will Be Balanced By 10,000 Acts Of Kindness, Too Often Unnoted And Invisible.

Contingency Is Rich And Fascinating; It Embodies An Exquisite Tension Between The Power Of Individuals To Modify History And The Intelligible Limits Set By Laws Of Nature. The Details Of Individual And Species's Lives Are Not Mere Frills, Without Power To Shape The Large-scale Course Of Events, But Particulars That Can Alter Entire Futures, Profoundly And Forever.

We Are Storytelling Animals, And Cannot Bear To Acknowledge The Ordinariness Of Our Daily Lives.

Sigmund Freud Often Remarked That Great Revolutions In The History Of Science Have But One Common, And Ironic, Feature: They Knock Human Arrogance Off One Pedestal After Another Of Our Previous Conviction About Our Own Self-importance.

All Science Is Intelligent Inference; Excessive Literalism Is Delusion, Not A Humble Bowing To Evidence.

Phony Psychics Like Uri Geller Have Had Particular Success In Bamboozling Scientists With Ordinary Stage Magic, Because Only Scientists Are Arrogant Enough To Think That They Always Observe With Rigorous And Objective Scrutiny, And Therefore Could Never Be So Fooled While Ordinary Mortals Know Perfectly Well That Good Performers Can Always Find A Way To Trick People.

[t]ruly Grand And Powerful Theories [...] Do Not And Cannot Rest Upon Single Observations. Evolution Is An Inference From Thousands Of Independent Sources, The Only Conceptual Structure That Can Make Unified Sense Of All This Disparate Information. The Failure Of A Particular Claim Usually Records A Local Error, Not The Bankruptcy Of A Central Theory. [...] If I Mistakenly Identify Your Father's Brother As Your Own Dad, You Don't Become Genealogically Rootless And Created De Novo. You Still Have A Father; We Just Haven't Located Him Properly.

The Spirit Of Plato Dies Hard. We Have Been Unable To Escape The Philosophical Tradition That What We Can See And Measure In The World Is Merely The Superficial And Imperfect Representation Of An Underlying Reality.

I View The Major Features Of My Own Odyssey As A Set Of Mostly Fortunate Contingencies. I Was Not Destined By Inherited Mentality Or Family Tradition To Become A Paleontologist. I Can Locate No Tradition For Scientific Or Intellectual Careers Anywhere On Either Side Of My Eastern European Jewish Background. I View My Serious And Lifelong Commitment To Baseball In Entirely The Same Manner: Purely As A Contingent Circumstance Of Numerous, Albeit Not Entirely Capricious, Accidents.

Always Be Suspicious Of Conclusions That Reinforce Uncritical Hope And Follow Comforting Traditions Of Western Thought.

Human Life Is The Result Of A Glorious Evolutionary Accident.

People May Believe Correct Things For The Damndest And Weirdest Of Wrong Reasons.

Even The Standard Example Of Ancient Nonsense - The Debate About Angels On Pinheads - Makes Sense Once You Realize That Theologians Were Not Discussing Whether Five Or Eighteen Would Fit, But Whether A Pin Could House A Finite Or An Infinite Number.

History Employs Evolution To Structure Biological Events In Time.

Skepticism Is The Agent Of Reason Against Organized Irrationalism--and Is Therefore One Of The Keys To Human Social And Civic Decency.

The Human Mind Delights In Finding Pattern—so Much So That We Often Mistake Coincidence Or Forced Analogy For Profound Meaning. No Other Habit Of Thought Lies So Deeply Within The Soul Of A Small Creature Trying To Make Sense Of A Complex World Not Constructed For It.

When Scientists Need To Explain Difficult Points Of Theory, Illustration By Hypothetical Example - Rather Than By Total Abstraction - Works Well (perhaps Indispensably) As A Rhetorical Device. Such Cases Do Not Function As Speculations In The Pejorative Sense - As Silly Stories That Provide Insight Into Complex Mechanisms - But Rather As Idealized Illustrations To Exemplify A Difficult Point Of Theory. (other Fields, Like Philosophy And The Law, Use Such Conjectural Cases As A Standard Device.

Evolution Is An Inference From Thousands Of Independent Sources, The Only Conceptual Structure That Can Make Unified Sense Of All This Disparate Information.

Humans Are Not The End Result Of Predictable Evolutionary Progress, But Rather A Fortuitous Cosmic Afterthought, A Tiny Little Twig On The Enormously Arborescent Bush Of Life, Which If Replanted From Seed, Would Almost Surely Not Grow This Twig Again.

Darwinian Natural Selection Only Yields Adaptation To Changing Local Environments, And Better Function In An Immediate Habitat Might Just As Well Be Achieved By Greater Simplicity In Form And Behavior As By Ever-increasing Complexity.

People Talk About Human Intelligence As The Greatest Adaptation In The History Of The Planet. It Is An Amazing And Marvelous Thing, But In Evolutionary Terms, It Is As Likely To Do Us In As To Help Us Along.

Our Creationist Detractors Charge That Evolution Is An Unproved And Unprovable Charade — A Secular Religion Masquerading As Science. They Claim, Above All, That Evolution Generates No Predictions, Never Exposes Itself To Test, And Therefore Stands As Dogma Rather Than Disprovable Science. This Claim Is Nonsense.

Why, Then, Do I Continue To Claim That Creationism Isn't Science? Simply Because These Relatively Few Statements Have Been Tested And Conclusively Refuted.

I Picture Several Reviewers Of My Own Books As Passing A Long Future Lodged Between Brutus And Judas In The Jaws Of Satan.

[evolution Is] One Of The Best Documented, Most Compelling And Exciting Concepts In All Of Science.

A Lot Of Scientists Hate Writing. Most Scientists Love Being In The Lab And Doing The Work And When The Work Is Done, They Are Finished.

A Man Does Not Attain The Status Of Galileo Merely Because He Is Persecuted; He Must Also Be Right.

[e]volutionists Sometimes Take As Haughty An Attitude Toward The Next Level Up The Conventional Ladder Of Disciplines: The Human Sciences. They Decry The Supposed Atheoretical Particularism Of Their Anthropological Colleagues And Argue That All Would Be Well If Only The Students Of Humanity Regarded Their Subject As Yet Another Animal And Therefore Yielded Explanatory Control To Evolutionary Biologists.

If Evolution Almost Always Occurs By Rapid Speciation In Small, Peripheral Isolates, Then What Should The Fossil Record Look Like? We Are Not Likely To Detect The Event Of Speciation Itself. It Happens Too Fast, In Too Small A Group, Isolated Too Far From The Ancestral Range.

But Our Ways Of Learning About The World Are Strongly Influenced By The Social Preconceptions And Biased Modes Of Thinking That Each Scientist Must Apply To Any Problem. The Stereotype Of A Fully Rational And Objective Scientific Method, With Individual Scientists As Logical (and Interchangeable) Robots, Is Self-serving Mythology.

In Their Recently Aborted Struggle To Inject Genesis Literalism Into Science Classrooms, Fundamentalist Groups Followed Their Usual Opportunistic Strategy Of Arguing Two Contradictory Sides Of A Question When A Supposed Rhetorical Advantage Could Be Extracted From Each.

We Pass Through This World But Once.

As A Graduate Student At Columbia University, I Remember The A Priori Derision Of My Distinguished Stratigraphy Professor Toward A Visiting Australian Drifter [a Supporter Of The Theory Of Continental Drift]. Today My Own Students Would Dismiss With Even More Derision Anyone Who Denied The Evident Truth Of Continental Drift - A Prophetic Madman Is At Least Amusing; A Superannuated Fuddy-duddy Is Merely Pitiful.

Perhaps I Am Just A Hopeless Rationalist, But Isn't Fascination As Comforting As Solace? Isn't Nature Immeasurably More Interesting For Its Complexities And Its Lack Of Conformity To Our Hopes? Isn't Curiosity As Wondrously And Fundamentally Human As Compassion?

In The Great Debates Of Early-nineteenth Century Geology, Catastrophists Followed The Stereotypical Method Of Objective Science-empirical Literalism. They Believed What They Saw, Interpolated Nothing, And Read The Record Of The Rocks Directly.

The Equation Of Evolution With Progress Represents Our Strongest Cultural Impediment To A Proper Understanding Of This Greatest Biological Revolution In The History Of Human Thought.

Orchids Manufacture Their Intricate Devices From The Common Components Of Ordinary Flowers, Parts Usually Fitted For Very Different Functions. If God Had Designed A Beautiful Machine To Reflect His Wisdom And Power, Surely He Would Not Have Used A Collection Of Parts Generally Fashioned For Other Purposes. Orchids Were Not Made By An Ideal Engineer; They Are Jury-rigged From A Limited Set Of Available Components. Thus, They Must Have Evolved From Ordinary Flowers.

The Darwinian Revolution Is About Essence. The Darwinian Revolution Is About Who We Are, It's What We're Made Of, It's What Our Life Means Insofar As Science Can Answer That Question.

Life Is Short, And Potential Studies Infinite. We Have A Much Better Chance Of Accomplishing Something Significant When We Follow Our Passionate Interests And Work In Areas Of Deepest Personal Meaning.

The Telephone Is The Greatest Single Enemy Of Scholarship; For What Our Intellectual Forebears Used To Inscribe In Ink Now Goes Once Over A Wire Into Permanent Oblivion.

If Genius Has Any Common Denominator, I Would Propose Breadth Of Interest And The Ability To Construct Fruitful Analogies Between Fields.

People Are Storytelling Creatures. We Like Stories That Go Somewhere, And Therefore We Like Trends - Because Trends Are Things That Either Get Better Or Get Worse, So We Can Either Rejoice Or Lament. But We Mistakenly Depict Many Things As Trends Moving In Some Direction. We Take The "full House" Of Variation In A System And Try To Represent It As A Single Number, When In Fact What We Should Be Doing Is Studying The Variation As It Expands And Contracts. If You Look At The History Of The Variation In All Its Complexity, Then You See There's No Trend.

If We Make This Readjustment To View Homo Sapiens As An Ultimate In Oddball Rarity, And Life At Bacterial Grade As The Common Expression Of A Universal Phenomenon, Then We Could Finally Ask The Truly Fundamental Question Raised By The Prospect Of Martian Fossils. If Life Originates As A General Property Of The Material Universe Under Certain Conditions (probably Often Realized), Then How Much Can The Basic Structure And Constitution Of Life Vary From Place To Independent Place?

We Are The Offspring Of History, And Must Establish Our Own Paths In This Most Diverse And Interesting Of Conceivable Universes—one Indifferent To Our Suffering, And Therefore Offering Us Maximum Freedom To Thrive, Or To Fail, In Our Own Chosen Way.

Very Little Comes Easily To Our Poor, Benighted Species (the First Creature, After All, To Experiment With The Novel Evolutionary Inventions Of Self-conscious Philosophy And Art). Even The Most "obvious," "accurate," And "natural" Style Of Thinking Or Drawing Must Be Regulated By History And Won By Struggle. Solutions Must Therefore Arise Within A Social Context And Record The Complex Interactions Of Mind And Environment That Define The Possibility Of Human Improvement.

Details Are All That Matters; God Dwells In These And You Never Get To See Him If You Don't Struggle To Get Them Right.

...we Must Be Wary Of Granting Too Much Power To Natural Selection By Viewing All Basic Capacities Of Our Brain As Direct Adaptations.

[t]he Effects Of General Change [in Literature] Are Most Tellingly Recorded Not In Alteration Of The Best Products, But In The Transformation Of The Most Ordinary Workaday Books; For When Potboilers Adopt The New Style, Then The Revolution Is Complete.

Ordinary Speciation Remains Fully Adequate To Explain The Causes And Phenomenology Of Punctuation.

Creation Science Has Not Entered The Curriculum For A Reason So Simple And So Basic That We Often Forget To Mention It: Because It Is False, And Because Good Teachers Understand Why It Is False. What Could Be More Destructive Of That Most Fragile Yet Most Precious Commodity In Our Entire Intellectual Heritage-good Teaching-than A Bill Forcing Our Honorable Teachers To Sully Their Sacred Trust By Granting Equal Treatment To A Doctrine Not Only Known To Be False, But Calculated To Undermine Any General Understanding Of Science As An Enterprise?.

Creationist Critics Often Charge That Evolution Cannot Be Tested, And Therefore Cannot Be Viewed As A Properly Scientific Subject At All. This Claim Is Rhetorical Nonsense.

When People Learn No Tools Of Judgment And Merely Follow Their Hopes, The Seeds Of Political Manipulation Are Sown.

God Was There When It Happened. We Were Not There.... Therefore, We Are Completely Limited To What God Has Seen Fit To Tell Us, And This Information Is In His Written Word.

It Seems The Height Of Antiquated Hubris To Claim That The Universe Carried On As It Did For Billions Of Years In Order To Form A Comfortable Abode For Us. Chance And Historical Contingency Give The World Of Life Most Of Its Glory And Fascination. I Sit Here Happy To Be Alive And Sure That Some Reason Must Exist For "why Me?" Or The Earth Might Have Been Totally Covered With Water, And An Octopus Might Now Be Telling Its Children Why The Eight-legged God Of All Things Had Made Such A Perfect World For Cephalopods.

The Extreme Rarity Of Transitional Forms In The Fossil Record Persists As A Trade Secret Of Paleontology. Evolutionary Trees That Adorn Our Textbooks Have Data Only At The Tips And Nodes Of Their Branches; The Rest Is Inference, However Reasonable, Not The Evidence Of Fossils.

When We Look To Presumed Sources Of Origin For Competing Evolutionary Explanations Of The Giraffe's Long Neck, We Find Either Nothing At All, Or Only The Shortest Of Speculative Conjectures. Length, Of Course, Need Not Correspond With Importance. Garrulous Old Polonius , In A Rare Moment Of Clarity, Reminded Us That "brevity Is The Soul Of Wit" (and Then Immediately Vitiated His Wise Observation With A Flood Of Woolly Words About Hamlet 's Madness.

We Are Here Because One Odd Group Of Fishes Had A Peculiar Fin Anatomy That Could Transform Into Legs For Terrestrial Creatures; Because The Earth Never Froze Entirely During An Ice Age; Because A Small And Tenuous Species, Arising In Africa A Quarter Of A Million Years Ago, Has Managed, So Far, To Survive By Hook And By Crook. We May Yearn For A ‘higher Answer’– But None Exists

The Contingency Of History (both For Life In General And For The Cultures Of Homo Sapiens ) And Human Free Will (in The Factual Rather Than Theological Sense) Are Conjoined Concepts, And No Better Evidence Can Be Produced Than The "experimental" Production Of Markedly Different Solutions In Identical Environments.

Each Worldview Was A Cultural Product, But Evolution Is True And Separate Creation Is Not. [...] Worldviews Are Social Constructions, And They Channel The Search For Facts. But Facts Are Found And Knowledge Progresses, However Fitfully. Fact And Theory Are Intertwined, And All Great Scientists Understand The Interaction.

[g]enes Make Enzymes, And Enzymes Control The Rates Of Chemical Processes. Genes Do Not Make "novelty Seeking" Or Any Other Complex And Overt Behavior. Predisposition Via A Long Chain Of Complex Chemical Reactions, Mediated Through A More Complex Series Of Life's Circumstances, Does Not Equal Identification Or Even Causation.

I Like To Summarize What I Regard As The Pedestal-smashing Messages Of Darwin's Revolution In The Following Statement, Which Might Be Chanted Several Times A Day, Like A Hare Krishna Mantra, To Encourage Penetration Into The Soul: Humans Are Not The End Result Of Predictable Evolutionary Progress, But Rather A Fortuitous Cosmic Afterthought, A Tiny Little Twig On The Enormously Arborescent Bush Of Life, Which, If Replanted From Seed, Would Almost Surely Not Grow This Twig Again, Or Perhaps Any Twig With Any Property That We Would Care To Call Consciousness.

Since We Proposed Punctuated Equilibria To Explain Trends, It Is Infuriating To Be Quoted Again And Again By Creationists-whether Through Design Or Stupidity, I Do Not Know-as Admitting That The Fossil Record Includes No Transitional Forms. Transitional Forms Are Generally Lacking At The Species Level, But They Are Abundant Between Larger Groups.

Recapitulation Provided A Convenient Focus For The Persuasive Racism Of White Scientists; They Looked To The Activities Of Their Own Children For Comparison With Normal Adult Behavior In Lower Races.

The Absence Of Fossil Evidence For Intermediary Stages Between Major Transitions In Organic Design, Indeed Our Inability, Even In Our Imagination, To Construct Functional Intermediates In Many Cases, Has Been A Persistent And Nagging Problem For Gradualist Accounts Of Evolution.

The Modern Theory Of Evolution Does Not Require Gradual Change. It In Fact, The Operation Of Darwinian Processes Should Yield Exactly What We See In The Fossil Record. It Is Gradualism That We Must Reject, Not Darwinism.

Theory Of Evolution

Not Since The Lord Himself Showed His Stuff To Ezekiel In The Valley Of Dry Bones Had Anyone Brought Such Grace And Skill To The Reconstruction Of Animals From Disarticulated Skeletons. Charles R. Knight, Most Celebrated Of Artists In The Reanimation Of Fossils, Painted All The Canonical Figures Of Dinosaurs That Fire Our Fear And Imagination To This Day.

I Am Not, Personally, A Believer Or A Religious Man In Any Sense Of Institutional Commitment Or Practice. But I Have A Great Respect For Religion, And The Subject Has Always Fascinated Me, Beyond Almost All Others (with A Few Exceptions, Like Evolution And Paleontology).

Results Rarely Specify Their Causes Unambiguously. If We Have No Direct Evidence Of Fossils Or Human Chronicles, If We Are Forced To Infer A Process Only From Its Modern Results, Then We Are Usually Stymied Or Reduced To Speculation About Probabilities. For Many Roads Lead To Almost Any Rome.

Surely The Mitochondrion That First Entered Another Cell Was Not Thinking About The Future Benefits Of Cooperation And Integration; It Was Merely Trying To Make Its Own Living In A Tough Darwinian World

Few Tragedies Can Be More Extensive Than The Stunting Of Life, Few Injustices Deeper Than The Denial Of An Opportunity To Strive Or Even To Hope, By A Limit Imposed From Without, But Falsely Identified As Lying Within.

Orchids Were Not Made By An Ideal Engineer; They Are Jury-rigged From A Limited Set Of Available Components.

I Am Glad That The Life Of Pandas Is So Dull By Human Standards, For Our Efforts At Conservation Have Little Moral Value If We Preserve Creatures Only As Human Ornaments; I Shall Be Impressed When We Show Solicitude For Warty Toads And Slithering Worms.

Acquired Characteristics Are Inherited In Technology And Culture. Lamarckian Evolution Is Rapid And Accumulative. It Explains The Cardinal Difference Between Our Past, Purely Biological Mode Of Change, And Our Current, Maddening Acceleration Toward Something New And Liberating- Or Toward The Abyss.

An Old Paleontological In Joke Proclaims That Mammalian Evolution Is A Tale Told By Teeth Mating To Produce Slightly Altered Descendant Teeth.

Science Is Not A Heartless Pursuit Of Objective Information; It Is A Creative Human Activity.

Evolving Life Must Experience A Vast Range Of Possibilities, Based On Environmental Histories So Unpredictable That No Realized Route - The Pathway To Consciousness In The Form Of Homo Sapiens Or Little Green Men, For Example - Can Be Construed As A Highway To Heaven, But Must Be Viewed As A Tortuous Track Rutted With Uncountable Obstacles And Festooned With Innumerable Alternative Branches. Any Reasonably Precise Repetition Of Our Earthly Route On Another Planet Therefore Becomes Wildly Improbable Even In A Trillion Cases.

I Love The Wry Motto Of The Paleontological Society, Meant Both Literally And Figuratively, For Hammers Are The Main Tool Of Our Trade: Frango Ut Patefaciam - I Break In Order To Reveal.

Natural Selection May Lead To Benefits For Species, But These `higher' Advantages Can Only Arise As Sequelae, Or Side Consequences, Of Natural Selection's Causal Mechanism: Differential Reproductive Success Of Individuals.

The Great Merit Of Stephen Gould's Account Of The Disastrous History Of Phychometrics Is That He Shifts The Argument From A Sterile Contest Between Environmentalists And Hereditarians And Turns It Into An Argument Between Those Who Are Impressed With What Our Biology Stops Us Doing And Those Who Are Impressed With What It Allows Us To Do.

No One Should Feel At All Offended Or Threatened By The Obvious Fact That We Are Not All Born Entirely Blank, Or Entirely The Same, In Our Mixture Of The Broad Behavioral Propensities Defining What We Call "temperament".

Pictures Are Not Incidental Frills To A Text; They Are Essences Of Our Distinctive Way Of Knowing.

Knowledge And Wonder Are The Dyad Of Our Worthy Lives As Intellectual Beings. Voyager Did Wonders For Our Knowledge, But Performed Just As Mightily In The Service Of Wonder And The Two Elements Are Complementary, Not Independent Or Opposed. The Thought Fills Me With Awe - A Mechanical Contraption That Could Fit In The Back Of A Pickup Truck, Traveling Through Space For Twelve Years, Dodging Around Four Giant Bodies And Their Associated Moons, And Finally Sending Exquisite Photos Across More Than Four Light-hours Of Space From The Farthest Planet In Our Solar System.

Theory And Fact Are Equally Strong And Utterly Interdependent; One Has No Meaning Without The Other. We Need Theory To Organize And Interpret Facts, Even To Know What We Can Or Might Observe. And We Need Facts To Validate Theories And Give Them Substance.

You Put Three Facts Together - That All Organisms Produce More Offspring That Can Survive, That There's Variation Among Organisms, And That At Least Some Of That Variation Is Inherited - And The Syllogistic Inference Is Natural Selection.

Perhaps Randomness Is Not Merely An Adequate Description For Complex Causes That We Cannot Specify. Perhaps The World Really Works This Way, And Many Events Are Uncaused In Any Conventional Sense Of The Word. Perhaps Our Gut Feeling That It Cannot Be So Reflects Only Our Hopes And Prejudices, Our Desperate Striving To Make Sense Of A Complex And Confusing World, And Not The Ways Of Nature.

There Is No Gene "for" Such Unambiguous Bits Of Morphology As Your Left Kneecap Or Your Fingernail. [...] Hundreds Of Genes Contribute To The Building Of Most Body Parts And Their Action Is Channeled Through A Kaleidoscopic Series Of Environmental Influences: Embryonic And Postnatal, Internal And External. Parts Are Not Translated Genes, And Selection Doesn't Even Work Directly On Parts.

We Who Revel In Nature's Diversity And Feel Instructed By Every Animal Tend To Brand Homo Sapiens As The Greatest Catastrophe Since The Cretaceous Extinction.

If We Are Still Here To Witness The Destruction Of Our Planet Some Five Billion Years Or More Hence, Then We Will Have Achieved Something So Unprecedented In The History Of Life That We Should Be Willing To Sing Our Swansong With Joy - Sic Transit Gloria Mundi.

History Of Life

I Have Often Been Amused By Our Vulgar Tendency To Take Complex Issues, With Solutions At Neither Extreme Of A Continuum Of Possibilities, And Break Them Into Dichotomies, Assigning One Group To One Pole And The Other To An Opposite End, With No Acknowledgment Of Subtleties And Intermediate Positions And Nearly Always With Moral Opprobrium Attached To Opponents.

Fundamentalism Is Rigorously And Systematically Used To Indoctrinate And Subjugate Young Minds. It Is A Contraceptive Designed To Prevent Intellectual Fertilization.

Evolution Is A Process Of Constant Branching And Expansion.

Life Is A Copiously Branching Bush, Continually Pruned By The Grim Reaper Of Extinction, Not A Ladder Of Predictable Progress.

When We Seek A Textbook Case For The Proper Operation Of Science, The Correction Of Certain Error Offers Far More Promise Than The Establishment Of Probable Truth. Confirmed Hunches, Of Course, Are More Upbeat Than Discredited Hypotheses. Since The Worst Traditions Of "popular" Writing Falsely Equate Instruction With Sweetness And Light, Our Promotional Literature Abounds With Insipid Tales In The Heroic Mode, Although Tough Stories Of Disappointment And Loss Give Deeper Insight Into A Methodology That The Celebrated Philosopher Karl Popper Once Labeled As "conjecture And Refutation.

Great Theories Are Expansive; Failures Mire Us In Dogmatism And Tunnel Vision.

We Have Become, By The Power Of A Glorious Evolutionary Accident Called Intelligence, The Stewards Of Life's Continuity On Earth. We Did Not Ask For This Role, But We Cannot Abjure It. We May Not Be Suited To It, But Here We Are.

True Majorities, In A Tv-dominated And Anti-intellectual Age, May Need Sound Bites And Flashing Lights And I Am Not Against Supplying Such Lures If They Draw Children Into Even A Transient Concern With Science. But Every Classroom Has One [oliver] Sacks , One [eric] Korn, Or One [jonathan] Miller , Usually A Lonely Child With A Passionate Curiosity About Nature, And A Zeal That Overcomes Pressures For Conformity. Do Not The One In Fifty Deserve Their Institutions As Well Magic Places, Like Cabinet Museums, That Can Spark The Rare Flames Of Genius?

Nothing Is More Dangerous Than A Dogmatic Worldview.

Skepticism's Bad Rap Arises From The Impression That, However Necessary The Activity, It Can Only Be Regarded As A Negative Removal Of False Claims. Not So... Proper Debunking Is Done In The Interest Of An Alternate Model Of Explanation, Not As A Nihilistic Exercise. The Alternate Model Is Rationality Itself, Tied To Moral Decency--the Most Powerful Joint Instrument For Good That Our Planet Has Ever Known.

Our Searches For Numerical Order Lead As Often To Terminal Nuttiness As To Profound Insight.

Contrary To Current Cynicism About Past Golden Ages, The Abstraction Known As 'the Intelligent Layperson' Does Exist - In The Form Of Millions Of Folks With A Passionate Commitment To Continuous Learning.

The Pathways That Have Led To Our Evolution Are Quirky, Improbable, Unrepeatable And Utterly Unpredictable.

We Are Glorious Accidents Of An Unpredictable Process With No Drive To Complexity, Not The Expected Results Of Evolutionary Principles That Yearn To Produce A Creature Capable Of Understanding The Mode Of Its Own Necessary Construction.

[in Natural History,] Great Discovery Often Requires A Map To A Hidden Mine Filled With Gems Then Easily Gathered By Conventional Tools, Not A Shiny New Space-age Machine For Penetrating Previously Inaccessible Worlds.

Heydrich, Eichmann, And Company Therefore Invoke The Usual Trick Of Argument For Breaking A True Continuum That Lacks A Compelling Point For Separation: Choose An Arbitrary Dividing Line And Then Treat It As A Self-evident Law Of Nature.

All Evolutionary Biologists Know That Variation Itself Is Nature's Only Irreducible Essence... I Had To Place Myself Amidst The Variation.

Antiessentialist Thinking Forces Us To View The World Differently. We Must Accept Shadings And Continua As Fundamental. We Lose Criteria For Judgment By Comparison To Some Ideal: Short People, Retarded People, People Of Other Beliefs, Colors, And Religions Are People Of Full Status.

We Live In An Essential And Unresolvable Tension Between Our Unity With Nature And Our Dangerous Uniqueness. Systems That Attempt To Place And Make Sense Of Us By Focusing Exclusively Either On The Uniqueness Or The Unity Are Doomed To Failure. But We Must Not Stop Asking And Questing Because The Answers Are Complex And Ambiguous.

The Fundamentalists, By 'knowing' The Answers Before They Start, And Then Forcing Nature Into The Straitjacket Of Their Discredited Preconceptions, Lie Outside The Domain Of Science - Or Any Honest Intellectual Inquiry.

Memory Is A Fascinating Trickster. Words And Images Have Enormous Power And Can Easily Displace Actual Experience Over The Years.

At A Minimum, In Explaining Evolutionary Pathways Through Time, The Constraints Imposed By History Rise To Equal Prominence With The Immediate Advantages Of Adaptation.

The Facts Of Nature Are What They Are, But We Can Only View Them Through The Spectacles Of Our Mind. Our Mind Works Largely By Metaphor And Comparison, Not Always (or Often) By Relentless Logic. When We Are Caught In Conceptual Traps, The Best Exit Is Often A Change In Metaphor Not Because The New Guideline Will Be Truer To Nature (for Neither The Old Nor The New Metaphor Lies "out There" In The Woods), But Because We Need A Shift To More Fruitful Perspectives, And Metaphor Is Often The Best Agent Of Conceptual Transition.

A Complete Theory Of Evolution Must Acknowledge A Balance Between "external" Forces Of Environment Imposing Selection For Local Adaptation And "internal" Forces Representing Constraints Of Inheritance And Development. Vavilov Placed Too Much Emphasis On Internal Constraints And Downgraded The Power Of Selection. But Western Darwinians Have Erred Equally In Practically Ignoring (while Acknowledging In Theory) The Limits Placed On Selection By Structure And Development What Vavilov And The Older Biologists Would Have Called "laws Of Form.

Theory Of Evolution

The Vigorous Branching Of Life's Tree, And Not The Accumulating Valor Of Mythical Marches To Progress, Lies Behind The Persistence And Expansion Of Organic Diversity In Our Tough And Constantly Stressful World. And If We Do Not Grasp The Fundamental Nature Of Branching As The Key To Life's Passage Across The Geological Stage, We Will Never Understand Evolution Aright.

Before Kuhn, Most Scientists Followed The Place-a-stone-in-the-bright-temple-of-knowledge Tradition, And Would Have Told You That They Hoped, Above All, To Lay Many Of The Bricks, Perhaps Even The Keystone, Of Truth's Temple. Now Most Scientists Of Vision Hope To Foment Revolution. We Are, Therefore, Awash In Revolutions, Most Self-proclaimed.

Darwin's Principle Of Natural Selection Leads To The Prediction That The Proper Way To Analyze Any Evolutionary Development Is To See The New Features As Adaptive To Environments. And That's A Perfectly Good Principle. The Problem Is That There Are Many Evolutionary Biologists Who View Everything That Happens In Evolution As Directly Evolved For Adaptive Benefit. And That Just Doesn't Work. Whenever You Build A Structure For Adaptive Reasons, The Structure Is Going To Exhibit Properties That Have Nothing To Do With Adaptation. They're Just Side Consequences.

What's Important Is That All Human Knowledge Be Made Available To All Intelligent People Who Want To Learn It.

Organisms [...] Are Directed And Limited By Their Past. They Must Remain Imperfect In Their Form And Function, And To That Extent Unpredictable Since They Are Not Optimal Machines. We Cannot Know Their Future With Certainty, If Only Because A Myriad Of Quirky Functional Shifts Lie Within The Capacity Of Any Feature, However Well Adapted To A Present Role.

Organisms Are Not Billiard Balls, Propelled By Simple And Measurable External Forces To Predictable New Positions On Life's Pool Table. Sufficiently Complex Systems Have Greater Richness. Organisms Have A History That Constrains Their Future In Myriad, Subtle Ways.

How Did Scientists Get Money In The Past? They Were Either Lucky And Independently Wealthy, Like Darwin, Or They Had Patrons, Like Galileo. Universities Or Governments Have Become Patrons Only In The Last Few Generations. Many Of The Great Scientists Of The Past Were In Debt To Their Patrons In The Same Sense That Modern Scientists Are Influenced By What Their Granting Agencies Want.

If New Species Arise Very Rapidly In Small, Peripherally Isolated Local Populations, Then The Great Expectation Of Insensibly Graded Fossil Sequences Is A Chimera. A New Species Does Not Evolve In The Area Of Its Ancestors; It Does Not Arise From The Slow Transformation Of All Its Forbears. Co-author With Niles Eldridge

I Strongly Reject Any Conceptual Scheme That Places Our Options On A Line, And Holds That The Only Alternative To A Pair Of Extreme Positions Lies Somewhere Between Them. More Fruitful Perspectives Often Require That We Step Off The Line To A Site Outside The Dichotomy.

Nature Is Objective, And Nature Is Knowable, But We Can Only View Her Through A Glass Darkly And Many Clouds Upon Our Vision Are Of Our Own Making: Social And Cultural Biases, Psychological Preferences, And Mental Limitations (in Universal Modes Of Thought, Not Just Individualized Stupidity).

Anything, Even The Conceptually Most Complex Material, Can Be Written For General Audiences Without Any Dumbing Down. Of Course You Have To Explain Things Carefully. This Goes Back To Galileo, Who Wrote His Great Books As Dialogues In Italian, Not As Treatises In Latin. And To Darwin, Who Wrote The Origin Of Species For General Readers. I Think A Lot Of People Pick Up Darwin's Book And Assume It Must Be A Popular Version Of Some Technical Monograph, But There Is No Technical Monograph. That's What He Wrote. So What I'm Doing Is Part Of A Great Humanistic Tradition.

If There Is Any Consistent Enemy Of Science, It Is Not Religion, But Irrationalism.

Still, Our Creationist Incubi, Who Would Never Let Facts Spoil A Favorite Argument, Refuse To Yield, And Continue To Assert The Absence Of All Transitional Forms By Ignoring Those That Have Been Found, And Continuing To Taunt Us With Admittedly Frequent Examples Of Absence.

Science Is All Those Things Which Are Confirmed To Such A Degree That It Would Be Unreasonable To Withhold One's Provisional Consent.

The Median Isn't The Message.

Life Began Three And A Half Billion Years Ago, Necessarily About As Simple As It Could Be, Because Life Arose Spontaneously From The Organic Compounds In The Primeval Oceans.

I Dreamed Of Becoming A Scientist, In General, And A Paleontologist, In Particular, Ever Since The Tyrannosaurus Skeleton Awed And Scared Me.

Iconography Becomes Even More Revealing When Processes Or Concepts, Rather Than Objects, Must Be Depicted For The Constraint Of A Definite "thing" Cedes Directly To The Imagination. How Can We Draw "evolution" Or "social Organization," Not To Mention The More Mundane "digestion" Or "self-interest," Without Portraying More Of A Mental Structure Than A Physical Reality? If We Wish To Trace The History Of Ideas, Iconography Becomes A Candid Camera Trained Upon The Scholar's Mind.

Is Uniformitarianism Necessary?

It Has Become, In My View, A Bit Too Trendy To Regard The Acceptance Of Death As Something Tantamount To Intrinsic Dignity. Of Course I Agree With The Preacher Of Ecclesiastes That There Is A Time To Love And A Time To Die - And When My Skein Runs Out I Hope To Face The End Calmly And In My Own Way. For Most Situations, However, I Prefer The More Martial View That Death Is The Ultimate Enemy - And I Find Nothing Reproachable In Those Who Rage Mightily Against The Dying Of The Light.

'creation Science' Has Not Entered The Curriculum For A Reason So Simple And So Basic That We Often Forget To Mention It: Because It Is False, And Because Good Teachers Understand Exactly Why It Is False.

Creation Science

Most Impediments To Scientific Understanding Are Conceptual Locks, Not Factual Lacks. Most Difficult To Dislodge Are Those Biases That Escape Our Scrutiny Because They Seem So Obviously, Even Ineluctably, Just. We Know Ourselves Best And Tend To View Other Creatures As Mirrors Of Our Own Constitution And Social Arrangements. ( Aristotle , And Nearly Two Millennia Of Successors, Designated The Large Bee That Leads The Swarm As A King.

It's True That The Level Of Scientific Knowledge Among Adults Is Very Low, But That's Not Because There Isn't A Natural Interest. I Think Most Kids Are Fascinated By The Natural World. I've Often Said That If You Could Quantify The Mental Power Involved In All The Dinosaur Names Correctly Known And Correctly Spelled By 5-year-old Kids In America, You Could Move Any Mountain On Earth.

Rifkin's Assertions Bear No Relationship To What I Have Observed And Practiced For 25 Years ... Either I Am Blind Or He Is Wrong - And I Think I Can Show, By Analyzing His Slipshod Scholarship And Basic Misunderstanding Of Science, That His World Is An Invention Constructed To Validate His Own Private Hopes ... Rifkin Shows No Understanding Of The Norms And Procedures Of Science: He Displays Little Comprehension Of What Science Is And How Scientists Work.

I Can Envision Observations And Experiments That Would Disprove Any Evolutionary Theory I Know.

It Is The Things We Think We Know - Because They Are So Elementary Or Because They Surround Us - That Often Present The Greatest Difficulties When We Are Actually Challenged To Explain Them.

I Would Trade All The Advantages Of Humanity To Be A Fly On The Wall When Franklin And Jefferson Discussed Liberty, Lenin And Trotsky Revolution, Newton And Halley The Shape Of The Universe, Or When Darwin Entertained Huxley And Lyell At Down.

Science Can't Tell Us What Our Life Means Ethically. It Can't Tell Us What We Are Meant To Do As Moral Creatures. But, Insofar As Science Can Understand What We're Made Of, And What We're Related To, The Darwinian Revolution Completely Revised Our Ideas About Who We Are And What We're Related To And How Long We've Been Here And Why We're On This Earth.

So Much Of Science Proceeds By Telling Stories.

Telling Stories

... Many Folks Take Them Seriously Because They Just 'know' That Evolution Can Never Be Seen In The Immediate Here And Now. In Fact, A Precisely Opposite Situation Prevails: Biologists Have Documented A Veritable Glut Of Cases For Rapid And Eminently Measurable Evolution On Timescales Of Years And Decades.

The Human Brain Became Large By Natural Selection (who Knows Why, But Presumably For Good Cause). Yet Surely Most "things" Now Done By Our Brains, And Essential Both To Our Cultures And To Our Very Survival, Are Epiphenomena Of The Computing Power Of This Machine, Not Genetically Grounded Darwinian Entities Created Specifically By Natural Selection For Their Current Function.

The World Is Full Of Signals That We Don't Perceive.

The Journalistic Tradition So Exalts Novelty And Flashy Discovery, As Reputable And Newsworthy, That Standard Accounts For The Public Not Only Miss The Usual Activity Of Science But Also, And More Unfortunately, Convey A False Impression About What Drives Research.

Complex Organisms Cannot Be Construed As The Sum Of Their Genes, Nor Do Genes Alone Build Particular Items Of Anatomy Or Behavior By Themselves. Most Genes Influence Several Aspects Of Anatomy And Behavior As They Operate Through Complex Interactions With Other Genes And Their Products, And With Environmental Factors Both Within And Outside The Developing Organism. We Fall Into A Deep Error, Not Just A Harmful Oversimplification, When We Speak Of Genes "for" Particular Items Of Anatomy Or Behavior.

Interaction With Others

As A Word, Ecology Has Been So Debased By Recent Political Usage That Many People Employ It To Identify Anything Good That Happens Far From Cities And Without Human Interference.

Facts And Theories Are Different Things, Not Rungs In A Hierarchy Of Increasing Certainty. Facts Are The World's Data. Theories Are Structures Of Ideas That Explain And Interpret Facts. Facts Do Not Go Away While Scientists Debate Rival Theories For Explaining Them. Einstein's Theory Of Gravitation Replaced Newton's, But Apples Did Not Suspend Themselves In Mid-air Pending The Outcome.

I Am Particularly Fond Of [emmanuel Mendes Da Costa's] Natural History Of Fossils Because This Treatise, More Than Any Other Work Written In English, Records A Short Episode Expressing One Of The Grand False Starts In The History Of Natural Science And Nothing Can Be Quite So Informative And Instructive As A Juicy Mistake.

Transitional Forms Are Generally Lacking At The Species Level, But They Are Abundant Between Larger Groups.

Evolution Has Encountered No Intellectual Trouble; No New Arguments Have Been Offered. Creationism Is A Home-grown Phenomenon Of American Sociocultural History-a Splinter Movement ... Who Believe That Every Word In The Bible Must Be Literally True, Whatever Such A Claim Might Mean.

If I Have Any Insight At All To Contribute It Is This: Find Out What You Are Really Good At And Stick To It.

Siphonophores Do Not Convey The Message A Favorite Theme Of Unthinking Romanticism That Nature Is But One Gigantic Whole, All Its Parts Intimately Connected And Interacting In Some Higher, Ineffable Harmony. Nature Revels In Boundaries And Distinctions; We Inhabit A Universe Of Structure. But Since Our Universe Of Structure Has Evolved Historically, It Must Present Us With Fuzzy Boundaries, Where One Kind Of Thing Grades Into Another.

Each Of The Major Sciences Has Contributed An Essential Ingredient In Our Long Retreat From An Initial Belief In Our Own Cosmic Importance. Astronomy Defined Our Home As A Small Planet Tucked Away In One Corner Of An Average Galaxy Among Millions; Biology Took Away Our Status As Paragons Created In The Image Of God; Geology Gave Us The Immensity Of Time And Taught Us How Little Of It Our Own Species Has Occupied.

I Like To Summarize What I Regard As The Pedestal-smashing Messages Of Darwin's Revolution In The Following Statement, Which Might Be Chanted Several Times A Day, Like A Hare Krishna Mantra, To Encourage Penetration Into The Soul: Humans Are Not The End Result Of Predictable Evolutionary Progress, But Rather A Fortuitous Cosmic Afterthought.

Human Consciousness Arose But A Minute Before Midnight On The Geological Clock. Yet We Mayflies Try To Bend An Ancient World To Our Purposes, Ignorant Perhaps Of The Messages Buried In Its Long History. Let Us Hope That We Are Still In The Early Morning Of Our April Day.

Charles Darwin Viewed The Fossil Record More As An Embarrassment Than As An Aid To His Theory.

World Views Are Social Constructions And They Channel The Search For Facts. But Facts Are Found And Knowledge Progresses, However Fitfully.

Nothing Is More Dangerous Than A Dogmatic Worldview - Nothing More Constraining, More Blinding To Innovation, More Destructive Of Openness To Novelty.

Everything Comes To Us In Fifteen-second Sound Bites And Photo Opportunities. All Possibility For Ambiguity - The Most Precious Trait Of Any Adequate Analysis - Is Erased.

What You See Is That The Most Outstanding Feature Of Life's History Is A Constant Domination By Bacteria.

History Does Include Aspects Of Directionality, And The Present Range Of Causes And Phenomena Does Not Exhaust The Realm Of Past Possibilities.

Zoocentrism Is The Primary Fallacy Of Human Sociobiology, For This View Of Human Behavior Rests On The Argument That If The Actions Of "lower" Animals With Simple Nervous Systems Arise As Genetic Products Of Natural Selection, Then Human Behavior Should Have A Similar Basis.

No Geologist Worth Anything Is Permanently Bound To A Desk Or Laboratory, But The Charming Notion That True Science Can Only Be Based On Unbiased Observation Of Nature In The Raw Is Mythology. Creative Work, In Geology And Anywhere Else, Is Interaction And Synthesis: Half-baked Ideas From A Bar Room, Rocks In The Field, Chains Of Thought From Lonely Walks, Numbers Squeezed From Rocks In A Laboratory, Numbers From A Calculator Riveted To A Desk, Fancy Equipment Usually Malfunctioning On Expensive Ships, Cheap Equipment In The Human Cranium, Arguments Before A Road Cut.

But If We Laugh With Derision, We Will Never Understand. Human Intellectual Capacity Has Not Altered For Thousands Of Years So Far As We Can Tell. If Intelligent People Invested Intense Energy In Issues That Now Seem Foolish To Us, Then The Failure Lies In Our Understanding Of Their World, Not In Their Distorted Perceptions.

Speciation Does Not Necessarily Promote Evolutionary Change; Rather, Speciation 'gathers In' And Guards Evolutionary Change By Locking And Stabilization For Sufficient Geological Time Within A Darwinian Individual Of The Appropriate Scale. If A Change In A Local Population Does Not Gain Such Protection, It Becomes-to Borrow Dawkins's Metaphor At A Macroevolutionary Scale-a Transient Duststorm In The Desert Of Time, A Passing Cloud Without Borders, Integrity, Or Even The Capacity To Act As A Unit Of Selection, In The Panorama Of Life's Phylogeny.
