Selection 2

"That synthesis holds that mutations to DNA create new variants of existing genes within a species. Natural selection, driven by competition for resources, allows the best-adapted individuals to produce the most surviving offspring. So adaptive variants of genes become more common. Although selection is often seen, even by biologists who should know better, as primarily negative, removing poorly adapted individuals, Charles Darwin understood that it was a powerful creative tool."

I am not the only one looking for a Generalized Selection Principle. The paragraph above was taken from the NYT article by Douglas H. Erwin, that you can read below.
