Evolution Quotes

“It's the old idea that the process of evolution is some push in the direction of greater complexity--in particular greater intellectual complexity. In one twig of the tree of life, namely ours, having a big brain happened to have advantages. But that's just what worked for a particular species of primate 5 to 7 million years ago.”

“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.”

“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.”

“The neutral zone of selective advantage in the neighbourhood of zero is thus so narrow that changes in the environment, and in the genetic constitution of species, must cause this zone to be crossed and perhaps recrossed relatively rapidly in the course of evolutionary change, so that many possible gene substitutions may have a fluctuating history of advance and regression before the final balance of selective advantage is determined.”

“Darwin was one of our finest specimens. He did superbly what human beings are designed to do: manipulate social information to personal advantage. The information in question was the prevailing account of how human beings, and all organisms, came to exist; Darwin reshaped it in a way that radically raised his social status. When he died in 1882, his greatness was acclaimed in newspapers around the world, and he was buried in Westminster Abbey, not far from the body of Isaac Newton. Alpha-male territory.”

“When environments change, they usually do so pretty rapidly, at rates with which adaptation by natural selection would be hard put to keep up. When such change occurs, the quality of your adaptation to your old habitat is irrelevant, and any competitive advantage you might have had may be eliminated at a stroke.”
