Ask Marilyn: Are Humans Still Evolving?
Justin Harper of Fullerton, California, writes:
Marilyn: I realize that evolution is slow, and we wouldn't see much change, if any, during the last two thousand years, but is humankind still evolving at all?
Probably not. Our cultural practices have mostly arrested the kind of change that came from survival of the fittest. Unfortunately, this also means that our need for health care will increase.
