POPSStone Age Humans Crossed Sahara in the Rain Wet spells While about 40 per cent of hydrocarbons in today's dust come from water-dependent plants, this rose to 60 per cent, first between 120,000 and 110,000 ago and again from 50,000 to 45,000 years ago. So the region seemed to be in the grip of unusually wet spells at the time. That may have been enough to allow sub-Saharan Stone Age Homo sapiens to migrate north: the first fossils of modern humans outside Africa date from 93,000 year ago in Israel. And both genetic analysis and archaeology show that humans didn't spread extensively beyond Africa until 50,000 years ago, suggesting a second migration at the time of the second wet spell. Fossil record Ian Tattersall of the American Museum of Natural History in New York is impressed by the findings. "They tie in approximately with the information we have from the fossil record."

POPSVanished Persian army said found in desert According to Herodotus (484-425 B.C.), Cambyses, the son of Cyrus the Great, sent 50,000 soldiers from Thebes to attack the Oasis of Siwa and destroy the oracle at the Temple of Amun after the priests there refused to legitimize his claim to Egypt.

"It would have had major effects on humans. Immediate effects would have been in the North and East, producing shockwaves, heat, flooding, wildfires, and a reduction and fragmentation of the human population."

POPSUC Berkeley scientists unveil skeleton that shares chimp, human features More: she is not "the missing link," a transitional creature between today's chimps and humans. This concept has been abandoned: We did not evolve from living champs or apes, but shared a common ancestor. Nor is she this long-sought "last common ancestor." That's because she's too young; chimps and humans are thought to have diverged between 5 million and 10 million years ago. Then we went our separate ways, each taking different evolutionary trajectories. But she's important because she is the closest we have come to this unfound "last common ancestor." She belonged to a new type of early hominid that was neither chimpanzee nor fully human.

POPSBritain BC / Britain AD Episode 1 of 2 (BC) and 1 of 3 (AD). Fascinating new understandings of British culture, history, and archaeology. Rather than being solely the inheritors of Roman, Anglo-Saxon, and Norman invaders, Pryor demonstrates that there was a sophisticated homegrown British culture that didn't just roll over when the next group of heavily-armed foreigners in boats showed up. And that in the absence of outside "civilizers" Britons didn't just revert to mud-wallowing barbarians.
