Did fist fighting change the course of human evolution?

The human hand is a beautiful product of evolution. Each one a finely crafted arrangement of 27 bones, our hands are among the most dexterous in the animal kingdom, and are every bit as capable of threading a needle as they are grasping the oar of a canoe.

Ancient humans may not have interbred with Neanderthals, after all

If you hail from outside of Africa, there's a decent chance that you share as much as 4% of your DNA with a long-extinct lineage of Neanderthals.

Animals who live fast and die young could be the key to human life…

Humans age very slowly, but the older we get, the more likely death gets. Not every animal follows that pattern though - some species live for only very short periods, but their age doesn't actually seem to affect when they die. Figuring out why these animals age the way they do could help us understand why humans… » 2/15/11 1:53pm 2/15/11 1:53pm

The Truth Behind the V Franchise

We mentioned earlier that V might be heading back to television. The big news is that the book that could inspire this V resurgence will hit store shelves tomorrow. But how well to you remember this show and its creator? Creator Kenneth Johnson gave us the original Bionic Woman, and we all know how that recent retread… » 2/04/08 11:15am 2/04/08 11:15am
