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?

More From Stephen Jay Gould

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.

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.

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

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 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.

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 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.

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.

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

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 Myriad Valleys Could Have Arisen Anywhere On The Landscape. The Current Positions Are Quite Accidental. If We Could Repeat The Experiment, We Might Obtain No Valleys At All, Or A Completely Different System. Yet We Now Stand At The Shore Line Contemplating The Fine Spacing Of Valleys And Their Even Contact With The Sea. How Easy It Is To Be Misled And To Assume That No Other Landscape Could Possibly Have Arisen.

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?

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.

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.

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.

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

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.

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.

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.

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

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.

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.

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.

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.

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.

Current Utility And Historical Origin Are Different Subjects.

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.

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?

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.

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.

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

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.

If A Man Dies Of Cancer In Fear And Despair, Then Cry For His Pain And Celebrate His Life. The Other Man, Who Fought Like Hell And Laughed In The End, But Also Died, May Have Had An Easier Time In His Final Months, But Took His Leave With No More Humanity.

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.

We Debase The Richness Of Both Nature And Our Own Minds If We View The Great Pageant Of Our Intellectual History As A Compendium Of New Information Leading From Primal Superstition To Final Exactitude. We Know That The Sun Is Hub Of Our Little Corner Of The Universe, And That Ties Of Genealogy Connect All Living Things On Our Planet, Because These Theories Assemble And Explain So Much Otherwise Disparate And Unrelated Information Not Because Galileo Trained His Telescope On The Moons Of Jupiter Or Because Darwin Took A Ride On A Galápagos Tortoise.

[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.

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.

Einstein's Theory Of Gravitation Replaced Newton's, But Apples Did Not Suspend Themselves In Mid-air, Pending The Outcome. And Humans Evolved From Apelike Ancestors Whether They Did So By Darwin's Proposed Mechanism Or By Some Other Yet To Be Discovered.

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.

The Silliest And Most Tendentious Of Baseball Writing Tries To Wrest Profundity From The Spectacle Of Grown Men Hitting A Ball With A Stick By Suggesting Linkages Between The Sport And Deep Issues Of Morality, Parenthood, History, Lost Innocence, Gentleness, And So On, Seemingly Ad Infinitum .

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 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.

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.

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.

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.

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).

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.

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

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.

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.

I Am Willing To Believe That My Unobtainable Sixty Seconds Within A Sponge Or A Flatworm Might Not Reveal Any Mental Acuity That I Would Care To Call Consciousness. But I Am Also Confident [...] That Vultures And Sloths, As Close Evolutionary Relatives With The Same Basic Set Of Organs, Lie On Our Side Of Any Meaningful (and Necessarily Fuzzy) Border And That We Are Therefore Not Mistaken When We Look Them In The Eye And See A Glimmer Of Emotional And Conceptual Affinity.

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.

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".

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.

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.

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".

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'.

The True Beauty Of Nature Is Her Amplitude; She Exists Neither For Nor Because Of Us, And Possesses A Staying Power That All Our Nuclear Arsenals Cannot Threaten (much As We Can Easily Destroy Our Puny Selves).

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

As We Discern A Fine Line Between Crank And Genius, So Also (and Unfortunately) We Must Acknowledge An Equally Graded Trajectory From Crank To Demagogue. When People Learn No Tools Of Judgment And Merely Follow Their Hopes, The Seeds Of Political Manipulation Are Sown.

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.

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

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.

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?.

We Cannot Win This Battle To Save Species And Environments Without Forging An Emotional Bond Between Ourselves And Nature As Well - For We Will Not Fight To Save What We Do Not Love.

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

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

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.

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.

With Copious Evidence Ranging From Plato's Haughtiness To Beethoven's Tirades, We May Conclude That The Most Brilliant People Of History Tend To Be A Prickly Lot.

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.

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.

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

But We All Recognise The Primary Foible Of Frail Humanity - Our Propensity For Embracing Hope And Shunning Logic, Our Tendency To Believe What We Desire Rather Than What We Observe.

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

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.

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.

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.

'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.

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 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.

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.

Hyper-selectionism Has Been With Us For A Long Time In Various Guises; For It Represents The Late Nineteenth Century's Scientific Version Of The Myth Of Natural Harmony All Is For The Best In The Best Of All Possible Worlds (all Structures Well Designed For A Definite Purpose In This Case). It Is, Indeed, The Vision Of Foolish Dr. Pangloss, So Vividly Satirized By Voltaire In Candide The World Is Not Necessarily Good, But It Is The Best We Could Possibly Have.

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.

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.

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.

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

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

We Should Take Comfort In Two Conjoined Features Of Nature: First, That Our World Is Incredibly Strange And Therefore Supremely Fascinating, Second, That However Bizarre And Arcane Our World Might Be, Nature Remains Potentially Comprehensible To The Human Mind.

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

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.

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.

My Own Field Of Paleontology Has Strongly Challenged The Darwinian Premise That Life's Major Transformations Can Be Explained By Adding Up, Through The Immensity Of Geological Time, The Successive Tiny Changes Produced Generation After Generation By Natural Selection.

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.

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.

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 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.

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.

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.

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

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.

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.

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.

Evolution Is A Process Of Constant Branching And Expansion.

Most Books, After All, Are Ephemeral; Their Specifics, Several Years Later, Inspire About As Much Interest As Daily Battle Reports From The Hundred Years' War.

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.

No One-liner Can Ever Be Optimal.

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.

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

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.

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

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.

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.

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

All Organisms Vary, And It's Just Folk Knowledge. You Just Have To Look Around A Room Of People, And Everybody Knows That It's True. Darwin Didn't Know The Mechanism Of Heredity, But You Don't Have To. You Just Need To Know The Fact Of It.

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.

The Truly Awesome Intellectuals In Our History Have Not Merely Made Discoveries; They Have Woven Variegated, But Firm, Tapestries Of Comprehensive Coverage. The Tapestries Have Various Fates: Most Burn Or Unravel In The Footsteps Of Time And The Fires Of Later Discovery. But Their Glory Lies In Their Integrity As Unified Structures Of Great Complexity And Broad Implication.

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.

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

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.

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.

Nature Is What She Is - Amoral And Persistent.

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.

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

Scientists Have Power By Virtue Of The Respect Commanded By The Discipline... We Live With Poets And Politicians, Preachers And Philosophers. All Have Their Ways Of Knowing, And All Are Valid In Their Proper Domain. The World Is Too Complex And Interesting For One Way To Hold All The Answers.

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.

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

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

Changing Environment

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

[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.

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.

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).

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.

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.

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.

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.

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.

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

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.

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

Any Decent Writer Writes Because There's Some Deep Internal Need To Keep Learning.

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.

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.

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

The Dogmatist Within Is Always Worse Than The Enemy Without.

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

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

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.

History Employs Evolution To Structure Biological Events In Time.

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.

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.

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

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.

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.

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.

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.

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

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.

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.

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

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.)

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.

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 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."

We Must [it Has Been Arued] Go Beyond Reductionism To A Holistic Recognition That Biology And Culture Interpenetrate In An Inextricable Manner.

... 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.

Paleontologists [fossil Experts] Have Paid An Exorbitant Price For Darwin's Argument. We Fancy Ourselves As The Only True Students Of Life's History, Yet To Preserve Our Favored Account Of Evolution By Natural Selection We View Our Data As So Bad That We Almost Never See The Very Process We Profess To Study.

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.
