In the life sciences, evolution is a change in the traits of living organisms over generations, including the emergence of new species. Since the development of modern genetics in the 1940s, evolution has been defined more specifically as a change in the frequency of alleles in a population from one generation to the next.In other fields evolution is used more generally to refer to any process of change over time.

Feb. 22, 2006 — Don't look now, but your backyard is evolving. It's no joke. There's a growing body of evidence that evolution is no longer something only seen either in this year's flu virus or Cretaceous tyrannosaur bones. It's happening everywhere, right now, and charging full-steam ahead.
