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."

POPSEuropeans Descended From Hunters, Not Farmers, Study Says The team investigated mitochondrial DNA"a permanent genetic marker passed from mothers to their offspring"recovered from the teeth and bones of 24 skeletons from 16 central European sites. These ancient humans all belonged to cultures that can be linked to the introduction of farming practices that began in present-day Israel, Jordan, and Syria around 12,000 years ago. The researchers identified which cultures the subjects belonged to by the decorations found on their pottery.

POPSHuman sacrifice at Cahokia Mounds? more (at source): But the "virgins" angle may be a bit of an overstatement, said Pauketat, but not by much. "In the book I do not use the word virgin. I used female sacrifices," he said, noting that close study of the pelvic area of some of 53 female skeletons found in a huge pit below the mound showed clear signs of childbirth. "They were selecting women of a certain age, but it's not like they're selecting virgins," he said. Most of the sacrificial victims were in their early 20s, he said.

POPSNeanderthals 'may have been killed off by modern humans' Steven Churchill, Associate Professor of Evolutionary Anthropology at Duke University in America, said the skeleton's rib injury had been a subject of intense speculation among anthropologists and paleontologists ever since he was discovered. "Some said it was interpersonal violence. Others said it could have been an accident," he said. "Did it involve only Neanderthals? Now we, for the first time, have brought some experimental evidence to bear on these questions." He said the Neanderthals' thrust spear produced a much more untidy wound than a projectile spear used by Homo Sapiens, which left a solitary rib puncture. "When a pig carcass was stabbed with a thrust spear its ribs were busted to hell. The high kinetic energy had caused a lot of damage in the area," he said. "However, whatever created that puncture was carrying fairly low kinetic energy at a low momentum. That's consistent with a spear-thrower delivered spear.

POPS"The oldest, most spectacular and rare work of art in the Americas" more: Kennedy found the brown and tan bone two years ago and put it under his sink. About two months ago, he took it out for cleaning and spotted unusual lines. He had been considering selling it at a flea market. Instead, he showed it to a fellow collector, William Roddenberry of Vero Beach, who was amazed. They took it to the Florida Museum of Natural History in Gainesville for examination. When Kennedy learned it was so historically valuable, he said, "It blew me away. I was absolutely baffled." The etched bone is being kept in a vault. The site where it was found isn't being disclosed.
