We are still evolving, says a new study. Fascinating article, promising much, hinting at a lot, but it's not the actual study, so it's hard to judge. This perspective, though, is interesting . . .
In the June 2003 issue of the research journal Current Anthropology, Helen Leach of the University of Otago, New Zealand wrote that skeletons from some populations in the human lineage have undergone a progressive shrinkage and weakening, and reduction in tooth size, similar to changes seen in domesticated animals. Humans seem to have domesticated themselves, she argued, causing physical as well as mental changes.
. . . but old hat.
