Natural Selection Darwin Quotes
This survival of the fittest which I have here sought to express in mechanical terms, is that which Mr. Darwin has called "natural selection", or the preservation of favoured races in the struggle for life. — Herbert Spencer
Nowhere was Darwin able to point to one bona fide case of natural selection having actually generated evolutionary change in nature....Ultimately, the Darwinian theory of evolution is no more nor less than the great cosmogenic myth of the twentieth century. — Michael Denton

The axe forgets what the tree remembers.
In the meantime, the educated public continues to believe that Darwin has provided all the relevant answers by the magic formula of random mutations plus natural selection -quite unaware of the fact that random mutations turned out to be irrelevant and natural selection tautology. — Arthur Koestler

The survival of the fittest is the ageless law of nature, but the fittest are rarely the strong. The fittest are those endowed with the qualifications for adaptation, the ability to accept the inevitable and conform to the unavoidable, to harmonize with existing or changing conditions. — Dave Smalley
The greatest oak was once a little nut who held her ground.
