I was taught over and over again that the accumulation of random mutations led to evolutionary change - led to new species. I believed…

Although random mutations influenced the course of evolution, their influence was mainly by loss, alteration, and refinement... Never, however, did that one mutation make…

Evolution by natural selection is not an idle hypothesis. The genetic variation on which selection acts is well understood in principle all the way…
