The Grants had documented natural selection in action. While beak size is clearly related to feeding strategies, it is also related to reproduction. Female finches tend to mate with males that ...

They weren't at all certain that natural populations contained enough genetic variation for natural selection to create ... of the American Museum of Natural History for 30 years.

Today, with access to heretofore unprecedented data sets for the study of human genetic variation, researchers can exploit the genetic signatures of natural selection using novel analytical methods.

Human beings are not a finished product. We’re still evolving every day and nowhere is that fact more apparent than in the mountains of the Tibetan Plateau where the march of evolution is still ...
