Were Neanderthals wiped out by our stomachs?

Bit of a strange one this. A study published in the Journal of Anthropological Sciences suggests a possible explanation for the disappearance of the Neanderthals – we ate them.

A Neanderthal jawbone appears to show marks similar to those found on deer remains from the early Stone Age. Lead researcher Fernando Rozzi, of the Centre National de la R├ęcherche Scientifique in Paris, believes that this idea has been suppressed in the past. “For years, people have tried to hide away from the evidence of cannibalism, but I think we have to accept it took place.”

I’m not sure eating Neanderthals is technically cannibalism, as they are a different species, but they’re human enough to make it pretty creepy. Urgh.

Beware the “super rats”

The governing principle of natural selection is that the fittest survive. In the case of rats, those with a genetic resistance to poison will survive attempts to exterminate them, and pass on this immunity to their descendants. Before you know it, we’ll be over-run by super rats.

Ratcatchers in Swindon are reporting a 500% increase in rodent populations, and Professor Robert Smith of the University of Huddersfield thinks that Darwin is to blame:

“Natural selection means that when you have a rat population in your town, poison will kill the ones that aren’t resistant, the ones that survive may have the gene, they then have babies who can receive the gene themselves,” he said.

“There are mutations and changes in their DNA that alter the ability of rats to deal with these poisons. It appears to be moving west and has now been located in Swindon and Bristol. It is a warning of things to come.”

An appropriate photo for Sunday

You may have already seen this image circulated around the press, but it’s worth another look:

Earlier this week astronauts aboard the Space Shuttle Atlantis undertook a mission to repair the Hubble telescope, and photographer Thierry Legault managed to catch them in the act. The spaceships appear as tiny dots in front of the vast Sun, but you can just make out the iconic shape of the Shuttle. More pics available here.
