10:06 AM | Indigenous societies’ ‘first contact’ typically brings collapse, but rebounds are possible
It was disastrous when Europeans first arrived in what would become Brazil — 95 percent of its population, the majority of its tribes, and essentially all of its urban and agricultural infrastructure vanished.

Contemporary Europeans have as many as three times more Neanderthal variants in genes involved in lipid catabolism than Asians and Africans. Although Neanderthals are extinct, fragments of their genomes persist in modern humans.
