The rapid accumulation of change is not always progress, and forward motion is not always an advance. - Jonathan Weiner

“Molecular biology has no history for the young scientist,” one of the old guard declared not long ago.

Evolution discloses a meaning in death, although the meaning is like some of the berries that Darwin tasted in the Galapagos, “acid & Austere.” There is a special providence in the fall of a sparrow. Even Drought bears fruit. Even death is a seed.

Geneticists will tell you that. Evolution is always happening. What they mean is that the genes of this generation are not precisely what they were the preceding generation. Nor will they be precisely the same in the next. And evolution is that change.
