No, says Dr. Marlene Zuk, professor, Department of Ecology, Evolution and Behavior, College of Biological Sciences, University of Minnesota:
Today, it seems everyone is fond of paleofantasies, stories about how humans lived eons ago, and we use them to explain why many elements of our lives, from the food we eat to the way we raise our children, seem distant from what nature intended. One need only look at the self-help industry’s output of books predicated on the notion that our behavior and bodies evolved under a certain set of circumstances—circumstances from which we deviate at our peril. Implicit in this idea is the assumption that we are no longer evolving, or at the very least, that evolution requires so much time that we can’t expect to have adapted to our current circumstances.
But popular theories about how our ancestors lived—and why we should emulate them—are often based on speculation, not scientific evidence, and they reflect a basic misunderstanding about how evolution works. “In fact,” says biologist Dr. Marlene Zuk, “there was never a time when everything about us—our bodies, our minds, and our behavior—was perfectly in synch with the environment.”
Gosh. Just think what that means, taken seriously.
(I’m not claiming Dr. Zuk takes it seriously. Maybe she does, but I am not claiming that. Girl needs her job.)
It certainly means that we humans must have some other dimension to ourselves than just nature.
I can assure you that the chipmunks, squirrels, ravens, jays, and Canada geese in my neighbourhood are perfectly in synch with their environment. And would be whether humans ever existed here or not.
She is actually saying that the philosophers are right (how shall we then live?), but wisely daren’t admit it in so many words.
