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.

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.

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?

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).

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.

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.

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.

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.

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.

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

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

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.

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

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.

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.

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

I Believe That We Can Still Have A Genre Of Scientific Books Suitable For And Accessible Alike To Professionals And Interested Laypeople. The Concepts Of Science, In All Their Richness And Ambiguity, Can Be Presented Without Any Compromise, Without Any Simplification Counting As Distortion, In Language Accessible To All Intelligent People. I Hope That This Book Can Be Read With Profit Both In Seminars For Graduate Students And If The Movie Stinks And You Forgot Your Sleeping Pills On The Businessman's Special To Tokyo.

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.

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

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

Science 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.

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.

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.

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

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.

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.

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

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.

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 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.

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.

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.

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.

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 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.

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

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).

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.

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.

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.

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

... 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.

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.

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?

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.

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.

Is Uniformitarianism Necessary?

We Are The Accidental Result Of An Unplanned Process ... The Fragile Result Of An Enormous Concatenation Of Improbabilities, Not The Predictable Product Of Any Definite Process.

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.

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

The Median Isn't The Message.

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.

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

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

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.

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.

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.

Without A Commitment To Science And Rationality In Its Proper Domain, There Can Be No Solution To The Problems That Engulf Us. Still, The Yahoos Never Rest.

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.

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.

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.

Advocates For A Single Line Of Progress Encounter Their Greatest Stumbling Block When They Try To Find A Smooth Link Between The Apparently Disparate Designs Of The Invertebrates And Vertebrates.

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.

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.

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.

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.)

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

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

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

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.

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

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.

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.

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

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.

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.

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

I Contend That The Continued Racial Classification Of Homo Sapiens Represents An Outmoded Approach To The General Problem Of Differentiation Within A Species. In Other Words, I Reject A Racial Classification Of Humans For The Same Reasons That I Prefer Not To Divide Into Subspecies The Prodigiously Variable West Indian Land Snails That Form The Subject Of My Own Research.

Differentiation

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.

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

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.

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.

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

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.

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

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

[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.

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.

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

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.

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.

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

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

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

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

Changing Environment

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.

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.

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?.

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.

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.

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.

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

The Dogmatist Within Is Always Worse Than The Enemy Without.

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

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.

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.

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

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

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.

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.

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.

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

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

Evolution Is A Process Of Constant Branching And Expansion.

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.

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 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.

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 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.

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.

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

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

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

The 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.

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

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 Enemy Of Knowledge And Science Is Irrationalism, Not Religion

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.

The Legends Of Fieldwork Locate All Important Sites Deep In Inaccessible Jungles Inhabited By Fierce Beasts And Restless Natives, And Surrounded By Miasmas Of Putrefaction And Swarms Of Tsetse Flies.

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.

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

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

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

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

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

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

Misunderstanding Of Probability May Be The Greatest Of All Impediments To Scientific Literacy.

History Employs Evolution To Structure Biological Events In Time.

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.
