Humans migrated to Mongolia much earlier than previously believed

Stone tools uncovered in Mongolia by an international team of archaeologists indicate that modern humans traveled across the Eurasian steppe about 45,000 years ago, according to a new University of California, Davis, study. The date is about 10,000 years earlier than archaeologists previously believed.

Neuroimaging's Bias Against Left-handers
