DNA neither cares nor knows. DNA just is. And we dance to its music.
The duration of every political phase is just as long as it takes to unveil its shortcomings and evil. While discovering its defects, it makes way for a new phase, liberated from these failings. Thus, these impairments that appear in a situation and destroy it are the very forces of human evolution, as they raise humanity to a more corrected state.
The torrent of centuries rolling over the human race, has continually brought new perfections, the cause of which, ever active though unseen, is found in the demands made by our senses, which always in their turns demand to be occupied.
Human nature, as manifested in tribalism and nationalism, provides the momentum of the machinery of human evolution.
The preoccupation with the choice of a mate both by male and female I regard as a continuing echo of the major selective force by which we have evolved.
It's our machines and our technologies that are now the major evolutionary forces acting upon us. It's not our political systems.
Culture represents a novelty in the world of nature, and it could have added an effective, unifying edge to the forces of natural selection.
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.
To defy heredity is to defy billions of years, to defy the first cell
The tide of evolution carries everything before it, thoughts no less than bodies, and persons no less than nations.
Natural selection, as it has operated in human history, favors not only the clever but the murderous.
Human social institutions can effect the course of human evolution. Just as climate, food supply, predators, and other natural forces of selection have molded our nature, so too can our culture.
