Twilight of the Neandertals - "Some 28,000 years ago in what is now the British territory of Gibraltar, a group of Neandertals eked out a living along the rocky Mediterranean coast. They were quite possibly the last of their kind [
meanwhile] around 30,000 years ago, the number of modern humans who lived to be old enough to be grandparents began to skyrocket." (

Neanderthal Lovin’! New research from evolutionary scientist Bruce Lahn suggests that humans and the
now extinct Neanderthal species mixed, and humans snatched up a valuable brain gene in the process. (The gene, MCPH1, and Lahn,
discussed last year on MeFi) This comes on the tails of yet another new study providing
morphological evidence that there was nontrivial interbreeding between humans and Neanderthals in Eurasia, despite the fact that Neanderthals may have been
genetically closer to chimps than humans. Contrary to popular imagination, though, the Neanderthal species had bigger brains and
sophisticated intellects, at least roughly on par with that of human beings. The gene regulates brain size during development, but its exact utility to humans is still unknown (
and controversial). The origin of this gene and the question of Neanderthal mixing will soon be answered more definitively by the, just launched,
2 year project to map the Neanderthal genome, headed by Svante Pääbo (profiled in recent
Smithsonian and
Wired articles).
Pääbo calls Lahn’s study "the most compelling case to date for a genetic contribution of Neandertals to modern humans."
