Caveman Competitiveness

National Geographic Channel showed an interesting documentary about human psychology today, cunningly disguised as a documentary about Neanderthals.
First, two groups of anthropologists were shown, bickering vehemently about whether modern humans evolved from Neanderthals or simply replaced them. Both sides bitterly defended their view.
Then, geneticists intervened and provided categorical proof of the latter theory. Their unveiled contempt for that fuzzy group of non-natural scientists was shown, as were the 'evolutionaries' unwaveringly sticking to their story. It was like watching a criminal still denying the crime after being shown the surveillance video.
In short, a great show about human nature.
