Quote

Life is a copiously branching bush, continually pruned by the grim reaper of extinction, not a ladder of predictable progress.

More quotes by Stephen Jay Gould

Image
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.
Stephen Jay Gould
Image
Mary Anning [is] probably the most important unsung (or inadequately sung) collecting force in the history of paleontology.
Stephen Jay Gould
Image
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.
Stephen Jay Gould
Image
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.
Stephen Jay Gould
Image
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.
Stephen Jay Gould
Image
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.

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.
Stephen Jay Gould
Image
The world, unfortunately, rarely matches our hopes and consistently refuses to behave in a reasonable manner.

The median isn't the message.

Image
History employs evolution to structure biological events in time.
Stephen Jay Gould
Image
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.
Stephen Jay Gould
Image
Memory is a fascinating trickster. Words and images have enormous power and can easily displace actual experience over the years.
Stephen Jay Gould
Image
The pathways that have led to our evolution are quirky, improbable, unrepeatable and utterly unpredictable.
Stephen Jay Gould
Image
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.
Stephen Jay Gould
Image
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.
Stephen Jay Gould

Guessing right for the wrong reason does not merit scientific immortality.
Stephen Jay Gould
Image
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.
Stephen Jay Gould
Image
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.
Stephen Jay Gould
Image
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.
Stephen Jay Gould
Image
Charles Darwin viewed the fossil record more as an embarrassment than as an aid to his theory.
