Scientists Discover the Oldest Human Fossils Outside Africa

Archaeologists in Israel have discovered the oldest fossil of a modern human outside Africa, suggesting that humans first migrated out of the content much earlier than previously believed. NPR reports: The scientists were digging in a cave called Misliya, on the slopes of Mount Carmel on the northern coast of Israel. "The cave is one of a series of prehistoric caves," says Mina Weinstein-Evron of the Zinman Institute of Archaeology at the University of Haifa, who led the team. "It's a collapsed cave, but people lived there before it collapsed." The cave had been occupied for several hundred thousand years, she says. All the archaeological evidence suggested that the ancient people who lived in the cave were hunter-gatherers. "They were hunting animals, mainly ungulates, like fallow dear, gazelle, aurochs [an extinct species of wild cattle] and other small animals," says Weinstein-Evron. "They built fireplaces throughout the length of the cave, again and again, in the same place, in the same sort of defined arrangement." Weinstein-Evron says she and her team wanted to find out which species of ancient humans lived in the cave. So, she says, they kept digging. "And among the animal bones and flint tools we found a jawbone, an upper jawbone of an individual," she says. A detailed analysis of the jawbone and the teeth confirmed that it indeed belonged to someone of our species, Homo sapiens. And when they dated the fossil, it turned out to be between 177,000 and 194,000 years old, making it the oldest known such fossil outside the African continent.
