On Darwin

"But what is astonishing," Olivia Judson writes, "is how much Darwin did know, and how far he saw. His imagination told him, for example, that many female animals have a sense of beauty — that they like to mate with the most beautiful males. For this he was ridiculed. But we know that he was right. Still more impressive: he was not afraid to apply his ideas to humans. He thought that natural selection had operated on us, just as it had on fruit flies and centipedes."

Elementary Watson, as Holmes would say. And the greatest idea of all time.
