I often don't agree with what Greg Cochran has to say (for instance, see here). However, his last post, a damning critique of the recent Pagani et al. paper on the Out of Africa exodus, was simply awesome:
I’ve been complaining about researchers being too narrow. This article is a spectacular example. But it’s not just the lead author: everyone whose name is on the paper must be assumed to be equally ignorant and incurious – as well as the reviewers, and editors, and for that matter anyone who doesn’t stay up all night laughing at them.
This is actually the second paper in only a matter of weeks from Wellcome Trust scientists that defies reason. Last month Ayub et al. claimed that the Kalash people of the Hindu Kush were an ancient north Eurasian population isolated from their neighbors for ~12,000 years. Check out my befuddlement here.
