"Tiny Bands of Humans

"Humans lived in tiny, separate bands for 100,000 years

"Human beings for 100,000 years lived in tiny, separate groups, facing harsh conditions that brought them to the brink of extinction, before they reunited and populated the world, genetic researchers have said.
'Who would have thought that as recently as 70,000 years ago, extremes of climate had reduced our population to such small numbers that we were on the very edge of extinction,' said paleontologist Meave Leakey, of Stony Brook University, New York. The genetic study examined for the first time the evolution of our species from its origins with "mitochondrial Eve," a female hominid who lived some 200,000 years ago, to the point of near extinction 70,000 years ago, when the human population dwindled to as little as 2,000. After this dismal period, the human race expanded quickly all over the African continent and emigrated beyond its shores until it populated all the corners of the Earth. The expansion marked the end of the Stone Age in Africa and the beginning of a cultural advancement that has led several archeologists to consider it the start of modern man, with the advent of language and complex and abstract thought. The migrations out of Africa are estimated to have begun some 60,000 years ago. But little was known about the human trajectory between Eve and that period. Published in the American Journal of Human Genetics, the study analyzed the maternally-transmitted mitochondrial DNA of human populations in southern and eastern Africa who appear to have diverged from other groups 90,000 to 150,000 years ago.
