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?

Since The Universe Must Contain Millions Of Appropriate Planets, Consciousness In Some Form - But Not With The Paired Eyes And Limbs, And The Brain Built Of Neurons In The Only Example We Know - May Evolve Frequently. But If Only One Origin Of Life In A Million Ever Leads To Consciousness, Then Martian Bacteria Most Emphatically Do Not Imply Little Green Men.

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.

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.

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.

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.

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.

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.

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

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

Some Evolutionists Will Protest That We Are Caricaturing Their View Of Adaptation. After All, Do They Not Admit Genetic Drift, Allometry, And A Variety Of Reasons For Nonadaptive Evolution?

Our World Is Not An Optimal Place, Fine Tuned By Omnipotent Forces Of Selection. It Is A Quirky Mass Of Imperfections, Working Well Enough (often Admirably); A Jury-rigged Set Of Adaptations Built Of Curious Parts Made Available By Past Histories In Different Contexts. A World Optimally Adapted To Current Environments Is A World Without History, And A World Without History Might Have Been Created As We Find It. History Matters; It Confounds Perfection And Proves That Current Life Transformed Its Own Past.

Evolution Is One Of The Two Or Three Most Primally Fascinating Subjects In All The Sciences.

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.

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.

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).

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

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.

Natural Selection Is A Theory Of Local Adaptation To Changing Environments. It Proposes No Perfecting Principles, No Guarantee Of General Improvement

The Only Universal Attribute Of Scientific Statements Resides In Their Potential Fallibility. If A Claim Cannot Be Disproven, It Does Not Belong To The Enterprise Of Science.

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

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.

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

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.

I Don't Think Academic Writing Ever Was Wonderful. However, Science Used To Be Much Less Specialized.

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.

Biological Determinism Is, In Its Essence, A Theory Of Limits. It Takes The Current Status Of Groups As A Measure Of Where They Should And Must Be ... We Inhabit A World Of Human Differences And Predilections, But The Extrapolation Of These Facts To Theories Of Rigid Limits Is Ideology.

Contingency Is A Thing Unto Itself, Not The Titration Of Determinism By Randomness.

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.

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

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.

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.

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.

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

Darwinian Evolution May Be The Most Truthful And Powerful Idea Ever Generated By Western Science, But If We Continue To Illustrate Our Conviction With An Indefensible, Unsupported, Entirely Speculative, And Basically Rather Silly Story, Then We Are Clothing A Thing Of Beauty In Rags - And We Should Be Ashamed, "for The Apparel Oft Proclaims The Man.

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).

... No Compelling Data To Support Its Anachronistic Social Darwinism.

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

No Rational Order Of Divine Intelligence Unites Species. The Natural Ties Are Genealogical Along Contingent Pathways Of History.

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.

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

Nothing Matches The Holiness And Fascination Of Accurate And Intricate Detail.

Honorable Errors Do Not Count As Failures In Science, But As Seeds For Progress In The Quintessential Activity Of Correction.

Evolution Is An Obstacle Course Not A Freeway; The Correct Analogue For Long-term Success Is A Distant Punt Receiver Evading Legions Of Would-be Tacklers In An Oddly Zigzagged Path Toward A Goal, Not A Horse Thundering Down The Flat.

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

Nothing Is More Dangerous Than A Dogmatic Worldview.

People Are Clever, But Almost No One Ever Devises An Optimal Quip Precisely At The Needed Moment. Therefore, Virtually All Great One-liners Are Later Inventions - Words That People Wished They Had Spouted, But Failed To Manufacture At The Truly Opportune Instant.

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.

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.

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.

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.

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.

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.

Obsolescence Is A Fate Devoutly To Be Wished, Lest Science Stagnate And Die.

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.

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.

The History Of Life Is A Tale Of Decimation And Later Stabilization Of Few Surviving Anatomies, Not A Story Of Steady Expansion And Progress.

Can I Pay Any Higher Tribute To A Man [george Gaylord Simpson] Than To State That His Work Both Established A Profession And Sowed The Seeds For Its Own Revision? If Simpson Had Reached Final Truth, He Either Would Have Been A Priest Or Would Have Chosen A Dull Profession. The History Of Life Cannot Be A Dull Profession.

[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.

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.

Eternal Vigilance, As They Say, Is The Price Of Freedom. Add Intellectual Integrity To The Cost Basis.

Why Get Excited Over This Latest Episode In The Long, Sad History Of American Anti-intellectualism? Let Me Suggest That, As Patriotic Americans, We Should Cringe In Embarrassment That, At The Dawn Of A New, Technological Millennium, A Jurisdiction In Our Heartland Has Opted To Suppress One Of The Greatest Triumphs Of Human Discovery.

Mary Anning [is] Probably The Most Important Unsung (or Inadequately Sung) Collecting Force In The History Of Paleontology.

The Literal Record Was Not A Hopelessly And Imperfect Fraction Of Truly Insensible Gradation Within Large Populations But An Accurate Reflection Of The Actual Process Identified By Evolutionists As The Chief Motor Of Biological Change. The Theory Of Punctuated Equilibrium Was, In Its Initial Formulation, Little More Than This Insight Adumbrated.

The Invalid Assumption That Correlation Implies Cause Is Probably Among The Two Or Three Most Serious And Common Errors Of Human Reasoning.

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.

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

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.

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".

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

Nature Is What She Is - Amoral And Persistent.

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.

The Classical Argument For Why A Supposedly Decent And Moral Creature Like Homo Sapiens Can Mistreat And Even Extirpate Other Species Rests Upon An Extreme Position In A Continuum. The Cartesian Tradition, Formulated Explicitly In The Seventeenth Century, But Developed In "folk" And Other Versions Throughout Human History No Doubt, Holds That Other Animals Are Little More Than Unfeeling Machines, With Only Humans Enjoying "consciousness," However Defined.

Something Deep Within Us Drives Accurate Messiness Into The Neat Channels Of Canonical Stories.

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.

Objectivity Cannot Be Equated With Mental Blankness; Rather, Objectivity Resides In Recognizing Your Preferences And Then Subjecting Them To Especially Harsh Scrutiny - And Also In A Willingness To Revise Or Abandon Your Theories When The Tests Fail (as They Usually Do).

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.

Unfortunately, All Life On Earth - The Only Life We Know - Represents, For All Its Current Variety, The Results Of A Single Experiment , For Every Earthly Species Evolved From The Common Ancestry Of A Single Origin. We Desperately Need A Repetition Of The Experiment (several Would Be Better, But Let's Not Be Greedy!) In Order To Make A Judgement. Mars Represents Our First Real Hope For A Second Experiment - The Sine Qua Non - For Any Proper Answer For The Question Of Questions.

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

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.

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.

We Must Shed The Old Stereotype Of Anarchists As Bearded Bomb Throwers Furtively Stalking About City Streets At Night.

In Science, 'fact' Can Only Mean 'confirmed To Such A Degree That It Would Be Perverse To Withhold Provisional Assent.' I Suppose That Apples Might Start To Rise Tomorrow, But The Possibility Does Not Merit Equal Time In Physics Classrooms.

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.

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.

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.

I'm Not A Great Deductive Thinker, But I Will Admit To Having Competence In A Very Wide Range Of Things - Not Being Afraid To Try To Write About Baseball, Choral Music And Dinosaurs In The Same Week And See Connections Among Them.

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.

We Pass Through This World But Once.

I Hardly Recognize What I Do Well. I Just Do It.

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.

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.

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.

The Argument That The Literal Story Of Genesis Can Qualify As Science Collapses On Three Major Grounds: The Creationists' Need To Invoke Miracles In Order To Compress The Events Of The Earth's History Into The Biblical Span Of A Few Thousand Years; Their Unwillingness To Abandon Claims Clearly Disproved, Including The Assertion That All Fossils Are Products Of Noah's Flood; And Their Reliance Upon Distortion, Misquote, Half-quote, And Citation Out Of Context To Characterize The Ideas Of Their Opponents.

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.

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.

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

Historical Science Is Not Worse, More Restricted, Or Less Capable Of Achieving Firm Conclusions Because Experiment, Prediction, And Subsumption Under Invariant Laws Of Nature Do Not Represent Its Usual Working Methods. The Sciences Of History Use A Different Mode Of Explanation, Rooted In The Comparative And Observational Richness In Our Data. We Cannot See A Past Event Directly, But Science Is Usually Based On Inference, Not Unvarnished Observation (you Don't See Electrons, Gravity, Or Black Holes Either).

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.

Look In The Mirror, And Don't Be Tempted To Equate Transient Domination With Either Intrinsic Superiority Or Prospects For Extended Survival.

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

Taxonomy (the Science Of Classification) Is Often Undervalued As A Glorified Form Of Filing-with Each Species In Its Folder, Like A Stamp In Its Prescribed Place In An Album; But Taxonomy Is A Fundamental And Dynamic Science, Dedicated To Exploring The Causes Of Relationships And Similarities Among Organisms. Classifications Are Theories About The Basis Of Natural Order, Not Dull Catalogues Compiled Only To Avoid Chaos.

I Was Lucky To Wander Into Evolutionary Theory, One Of The Most Exciting And Important Of All Scientific Fields. I Had Never Heard Of It When I Started At A Rather Tender Age; I Was Simply Awed By Dinosaurs. I Thought Paleontologists Spent Their Lives Digging Up Bones And Putting Them Together, Never Venturing Beyond The Momentous Issue Of What Connects To What. Then I Discovered Evolutionary Theory. Ever Since Then, The Duality Of Natural History-richness In Particularities And Potential Union In Underlying Explanation-has Propelled Me.

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.

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.

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.

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.

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.

'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

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.

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

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

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.

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.

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

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.

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.

In His Anti-darwinian Book... (and Eponymously Named The Neck Of The Giraffe ), Francis Hitching Tells The Story... "the Need To Survive By Reaching Ever Higher For Food Is, Like So Many Darwinian Explanations Of Its Kind, Little More Than A Post Hoc Speculation." Hitching Is Quite Correct, But He Rebuts A Fairy Story That Darwin Was Far Too Smart To Tell - Even Though The Tale Later Entered Our High School Texts As A "classic Case" Nonetheless.

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

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.

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.

... Each With Its Own Beauty, And Each With A Story To Tell.

History Employs Evolution To Structure Biological Events In Time.

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

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.

If You Defend A Behavior By Arguing That People Are Programmed Directly For It, Then How Do You Continue To Defend It If Your Speculation Is Wrong, For The Behavior Then Becomes Unnatural And Worthy Of Condemnation. Better To Stick Resolutely To A Philosophical Position On Human Liberty: What Free Adults Do With Each Other In Their Own Private Lives Is Their Business Alone. It Need Not Be Vindicated And Must Not Be Condemned By Genetic Speculation.

Science Is An Integral Part Of Culture. It's Not This Foreign Thing, Done By An Arcane Priesthood. It's One Of The Glories Of The Human Intellectual Tradition.

Sure We Fit. We Wouldn't Be Here If We Didn't. But The World Wasn't Made For Us And It Will Endure Without Us.

It Is So Hard For An Evolutionary Biologist To Write About Extinction Caused By Human Stupidity. Let Me Then Float An Unconventional Plea, The Inverse Of The Usual Argument. The Extinction Of Partula Is Unfair To Partula. That Is The Conventional Argument, And I Do Not Challenge Its Primacy. But We Need A Humanistic Ecology As Well, Both For The Practical Reason That People Will Always Touch People More Than Snails Do Or Can, And For The Moral Reason That Humans Are Legitimately The Measure Of All Ethical Questions For These Are Our Issues, Not Nature's.

Ethical Questions

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.

... 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.

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

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.

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.

Theory-free Science Makes About As Much Sense As Value-free Politics.

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.

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

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.

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

[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 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.

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

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.

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

Our Current Drug Crisis Is A Tragedy Born Of A Phony System Of Classification. For Reasons That Are Little More Than Accidents Of History, We Have Divided A Group Of Nonfood Substances Into Two Categories: Items Purchasable For Supposed Pleasure (such As Alcohol), And Illicit Drugs.

Life Shows No Trend To Complexity In The Usual Sense-only An Asymmetrical Expansion Of Diversity Around A Starting Point Constrained To Be Simple.

We May Need Simple And Heroic Legends For That Peculiar Genre Of Literature Known As The Textbook. But Historians Must Also Labor To Rescue Human Beings From Their Legends In Science If Only So That We May Understand The Process Of Scientific Thought Aright.

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".

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

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

Death Is The Ultimate Enemy - And I Find Nothing Reproachable In Those Who Rage Mightily Against The Dying Of The Light.

Mass Extinctions May Not Threaten Distant Futures, But They Are Decidedly Unpleasant For Species Caught Up In The Throes Of Their Power.

Mass Extinction

I Am, Somehow, Less Interested In The Weight And Convolutions Of Einstein’s Brain Than In The Near Certainty That People Of Equal Talent Have Lived And Died In Cotton Fields And Sweatshops.

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.

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.

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.

Any Human Being Is Really Good At Certain Things. The Problem Is That The Things You're Good At Come Naturally. And Since Most People Are Pretty Modest Instead Of An Arrogant S.o.b. Like Me, What Comes Naturally, You Don't See As A Special Skill. It's Just You. It's What You've Always Done.

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.

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.

Among People I Have Met, The Few Whom I Would Term “great” All Share A Kind Of Unquestioned, Fierce Dedication; An Utter Lack Of Doubt About The Value Of Their Activities (or At Least An Internal Impulse That Drives Through Any Such Angst); And Above All, A Capacity To Work (or At Least To Be Mentally Alert For Unexpected Insights) At Every Available Moment Of Every Day Of Their Lives.

Human Life Is The Result Of A Glorious Evolutionary Accident.

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.

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!'

For Dawkins, Evolution Is A Battle Among Genes, Each Seeking To Make More Copies Of Itself. Bodies Are Merely The Places Where Genes Aggregate For A Time.

In Our Struggle To Understand The History Of Life, We Must Learn Where To Place The Boundary Between Contingent And Unpredictable Events That Occur But Once And The More Repeatable, Lawlike Phenomenon That May Pervade Life's History As Generalities.

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.

The Basic Formulation, Or Bare-bones Mechanics, Of Natural Selection Is A Disarmingly Simple Argument, Based On Three Undeniable Facts (overproduction Of Offspring, Variation, And Heritability) And One Syllogistic Inference (natural Selection, Or The Claim That Organisms Enjoying Differential Reproductive Success Will, On Average, Be Those Variants That Are Fortuitously Better Adapted To Changing Local Environments, And That These Variants Will Then Pass Their Favored Traits To Offspring By Inheritance).

As In 1925, Creationists Are Not Battling For Religion. They Have Been Disowned By Leading Church Men Of All Persuasions, For They Debase Religion Even More Than They Misconstrue Science. They Are A Motley Collection To Be Sure, But Their Core Of Practical Support Lies With The Evangelical Right, And Creationism Is A Mere Stalking Horse Or Subsidiary Issue In A Political Program...the Enemy Is Not Fundamentalism; It Is Intolerance. In This Case, The Intolerance Is Perverse Since It Masquerades Under The 'liberal' Rhetoric Of 'equal Time'.

Is Uniformitarianism Necessary?

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.

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.

The Board Transported Its Jurisdiction To A Never-never Land Where A Dorothy Of The New Millennium Might Exclaim: "they Still Call It Kansas, But I Don't Think We're In The Real World Anymore."

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.

The Real Tragedy Of Human Existence Is Not That We Are Nasty By Nature, But That A Cruel Structural Asymmetry Grants To Rare Events Of Meanness Such Power To Shape Our History.

Few Intellectual Tyrannies Can Be More Recalcitrant Than The Truths That Everybody Knows And Nearly No One Can Defend With Any Decent Data (for Who Needs Proof Of Anything So Obvious). And Few Intellectual Activities Can Be More Salutary Than Attempts To Find Out Whether These Rocks Of Ages Might Crumble At The Slightest Tap Of An Informational Hammer.

The Essence Of Darwinism Lies In Its Claim That Natural Selection Creates The Fit. Variation Is Ubiquitous And Random In Direction. It Supplies Raw Material Only. Natural Selection Directs The Course Of Evolutionary Change.

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.

No More Harmful Nonsense Exists Than [the] Common Supposition That Deepest Insight Into Great Questions About The Meaning Of Life Or The Structure Of Reality Emerges Most Readily When A Free, Undisciplined, And Uncluttered (read, Rather, Ignorant And Uneducated) Mind Soars Above Mere Earthly Knowledge And Concern.

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

The Most Erroneous Stories Are Those We Think We Know Best - And Therefore Never Scrutinize Or Question.

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.

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.

The Origin Of Homo Sapiens, As A Tiny Twig On An Improbable Branch Of A Contingent Limb On A Fortunate Tree, Lies Well Below The Boundary.

The World Is Too Complex For Subsumption Under Any General Theory Of Change.

Change Is More Often A Rapid Transition Between Two Stable States Than A Continuous Transformation At Slow And Steady Rates. . . .change Occurs In Large Leaps Following A Slow Accumulation Of Stress That A System Resists Until It Reaches The Breaking Point. Heat Water, And It Eventually Boils. Oppress The Workers More And More And Bring On The Revolution.

The Most Important Scientific Revolutions All Include, As Their Only Common Feature, The Dethronement Of Human Arrogance From One Pedestal After Another Of Previous Convictions About Our Centrality In The Cosmos.

The Median Isn't The Message.

Guessing Right For The Wrong Reason Does Not Merit Scientific Immortality.

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.)

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.

I Despair Of Persuading People To Drop The Familiar And Comforting Tactic Of Dichotomy. Perhaps, Instead, We Might Expand The Framework Of Debates By Seeking Other Dichotomies More Appropriate Than, Or Simply Different From, The Conventional Divisions. All Dichotomies Are Simplifications, But The Rendition Of A Conflict Along Differing Axes Of Several Orthogonal Dichotomies Might Provide An Amplitude Of Proper Intellectual Space Without Forcing Us To Forgo Our Most Comforting Tool Of Thought.

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.

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.

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.

Forelimbs Of People, Porpoises, Bats And Horses Provide The Classic Example Of Homology In Most Textbooks. They Look Different, And Do Different Things, But Are Built Of The Same Bones. No Engineer, Starting From Scratch Each Time, Would Have Built Such Disparate Structures From The Same Parts.

So Much Of Science Proceeds By Telling Stories.

Telling Stories

The Enemy Is Not Fundamentalism; It Is Intolerance. In This Case, The Intolerance Is Perverse Since It Masquerades Under The "liberal" Rhetoric Of "equal Time." But Mistake It Not.

The Dogmatist Within Is Always Worse Than The Enemy Without.

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.

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