As with any other species, human populations are shaped by the usual forces of natural selection, like famine, disease or climate. A new force is now coming into focus. It is one with a surprising implication — that for the last 20,000 years or so, people have inadvertently been shaping their own evolution.My question is, why is this so surprising? I've long just assumed that culture exhibited both pro- and anti-evolutionary forces. Who knew this was up for debate?
In other news, that show Archer is hilarious. Whether it is working for or against evolution has yet to be seen.
