Outdated but still valid.

It was already a bit old when I got my hands on it... How old? Well, the author was discussing Neanderthal heritage in current populations, and I already know that I'm ~2.6% Neanderthal thanks to 23andMe.
Still, a lot of the ideas presented are very valid, if you have it around go ahead and read it, but there might be updated material somewhere else, and that's perfectly acceptable, that's science working for us!
