The story about human-neanderthal inter-breeding has now made the rounds — here's one version from NewScientist. (The image is from there too.) The news is based on genome evidence from Neanderthal bones (found in the Vindija Cave pictured), and it doesn't look like the conclusions are being instantly accepted by everybody, as this story indicates.
But I've got the clincher evidence here: Neanderthals are still among us, and using computers. Last night, we got dozens of blog spams, basically the same (some URLs varied), as comments on a bunch of different posts.
OK, seriously, I don't have a clue about Neanderthal intelligence and maybe they were good folks, but the spam attack was primitive.
