Evolution by natural selection is not an idle hypothesis. The genetic variation on which selection acts is well understood in principle all the way down to the molecular level.

The second half of the 20th century was a golden age of molecular biology, and it was one of the golden ages of the history of science. Molecular biology was so successful and made such a powerful alliance with the medical scientists that the two together just flourished. And they continue to flourish.

It's always been a great survival value for people to believe they belong to a superior tribe. That's just in human relationships.

The true evolutionary epic, retold as poetry, is as intrinsically ennobling as any religious epic.

The ant world is a tumult, a noisy world of pheromones being passed back and forth.

Man's destiny is to know, if only because societies with knowledge culturally dominate societies that lack it. Luddites and anti-intellectuals do not master the differential equations of thermodynamics or the biochemical cures of illness. They stay in thatched huts and die young.

We don't know nearly enough about the complexities of Nature. If we think we can eliminate natural ecosystems and substitute prosthetic devices, i.e. clean air or water with fusion energy - we are kidding ourselves.
