Division of labor

The Economist on a theory of Division of Labor

NEANDERTHAL man was a strong, large-brained, skilful big-game hunter who had survived for more than 200,000 years in the harsh European climates of the last Ice Age. But within a few thousand years of the arrival of modern humans in the continent, he was extinct. Why that happened is a matter of abiding interest to anthropologically inclined descendants of those interloping moderns. The extinction of Neanderthal man has been attributed variously to his having lower intelligence than modern humans, to worse language skills, to cruder tools, or even to the lack of a propensity for long-distance trade. The latest proposal, though, is that it is not so much Neanderthal man that was to blame, as modern woman.
