More often than not it brought a worse diet, longer hours of work, greater risk of starvation, crowded living conditions, greatly increased susceptibility to disease, new forms of insecurity and uglier forms of hierarchy.
  • Bailey and Geary found population density did indeed track closely with brain size, but in a surprising way. The reassuring quality of that belief makes those in the opposing camp wonder if some of the logic of skeptics is tinged with wishful thinking. The aim of their investigation was to explore how cranial size changed as our species adapted to an increasingly complex social environment between.9 million and 10,000 years ago.
  • Scaling is also why nobody seems too surprised by the large brains of the. Homo sapiens with the biggest brains lived 20,000 to 30,000 years ago in Europe. On the notion that modern humans are simply daintier but otherwise.

He speculates that the organs wiring pattern became more streamlined, the neurochemistry shifted, or perhaps both happened in tandem to boost our cognitive ability. But a boom in the human population between 20,000 and 10,000 years ago greatly improved the odds of such a fortuitous development.
  3. It is likely that human races are evolving away from each other, says. Some scientists are alarmed by claims of ethnic differences.

Given such uncertainties, researchers are more likely to be persuaded that a mutation has been recently selected if they understand its function and if its rise in prevalence meshes well with known human migratory routes.
