The theory of evolution by cumulative natural selection is the only theory we know of that is in principle capable of explaining the existence of organized complexity
Richard Dawkins
The expression often used by Mr. Herbert Spencer of the Survival of the Fittest is more accurate, and is sometimes equally convenient.
Charles R. Darwin
The probability of life originating from accident is comparable to the probability of the unabridged dictionary resulting from an explosion in a printing shop.
Edward Conklin
Promise yourself to live your life as a revolution and not just a process of evolution.
Anthony J. D'Angelo
Creationist critics often charge that evolution cannot be tested, and therefore cannot be viewed as a properly scientific subject at all. This claim is rhetorical nonsense.
Stephen Jay Gould
Nothing will benefit human health and increase the chances for survival of life on Earth as much as the evolution to a vegetarian diet.
Albert Einstein
Since evolution became fashionable, the glorification of Man has taken a new form.
Bertrand Russell
Evolution is not a force but a process. Not a cause but a law.
John Morley
Change is at the very core of evolution and without it, all creatures would look alike and behave the same way.
Martin Dansky
Evolutionists will continue to find missing links until all will be amiss for we will still ask how we got here.
Martin Dansky
Civilization is a progress from an indefinite, incoherent homogeneity toward a definite, coherent heterogeneity.
Herbert Spencer
Evolution seems to close the heart to some of the plainest spiritual truths while it opens the mind to the wildest guesses advanced in the name of science.
William Jennings Bryan
It is natural human impulse to think of evolution as a long chain of improvements, of a never-ending advance towards largeness and complexity in a word, towards us. We flatter ourselves. Most of the real diversity in evolution has been small-scale. We large things are just flukes an interesting side branch.
William Cullen Bryant
My view is that evolution will continue to evolve!
Tony Buzan
Evolution tells us where we came from, not where we can go.
Jerry Coyne
