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

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.

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

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

Changing Environment

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

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.

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.

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

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).

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.

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.

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

Theory Of Evolution

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.

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 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.

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.

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

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.

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

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.

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.

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.

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.

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.

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.

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.

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

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.

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.

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.

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

... 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.

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.

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

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.

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

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

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

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.

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

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

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.

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?

The Enemy Of Knowledge And Science Is Irrationalism, Not Religion

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.

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.

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.

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

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.

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

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

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.)

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.

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.

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

No One-liner Can Ever Be Optimal.

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.

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

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.

I Am Not [...] Asserting That Humans Are Either Genial Or Aggressive By Inborn Biological Necessity. Obviously, Both Kindness And Violence Lie Within The Bounds Of Our Nature Because We Perpetrate Both, In Spades. I Only Advance A Structural Claim That Social Stability Rules Nearly All The Time And Must Be Based On An Overwhelmingly Predominant (but Tragically Ignored) Frequency Of Genial Acts, And That Geniality Is Therefore Our Usual And Preferred Response Nearly All The Time. [...] [t]he Center Of Human Nature Is Rooted In Ten Thousand Ordinary Acts Of Kindness That Define Our Days.

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.

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

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

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.

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

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.

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.

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

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.

Support Systems

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.

Nothing Is More Dangerous Than A Dogmatic Worldview.

The Proof Of Evolution Lies In Those Adaptations That Arise From Improbable Foundations.

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

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.

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

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.

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

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.

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.

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

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).

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.

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.

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!'

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.

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.

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.

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

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

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.

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.

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

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

History Employs Evolution To Structure Biological Events In Time.

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.

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

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

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

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

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.

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).

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.

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.

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.

[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.

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.

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.

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.

Evolution Is A Process Of Constant Branching And Expansion.

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.

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

The Center Of Human Nature Is Rooted In Ten Thousand Ordinary Acts Of Kindness That Define Our Days.

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.

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.

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

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

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.

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

Mass Extinction

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.

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.

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.

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.

[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.

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

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 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 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.

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.

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

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.

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.

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.

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

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).

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.

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 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

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.

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.

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

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.

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

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.

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.

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".

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.

Good Scholars Struggle To Understand The World In An Integral Way (pedants Bite Off Tiny Bits And Worry Them To Death). These Visions Of Reality [...] Demand Our Respect, For They Are An Intellectual's Only Birthright. They Are Often Entirely Wrong And Always Flawed In Serious Ways, But They Must Be Understood Honorably And Not Subjected To Mayhem By The Excision Of Patches.

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

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

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

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.

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.

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

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

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

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.

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

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.

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

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.

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.

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.

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.

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).

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

... A Local, Indigenous, American Bizarre-ity.

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?

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.

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

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.

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.

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.

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

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.

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.

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.

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.

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.

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.

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.

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.

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 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.

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.

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.

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.

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

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.

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.
