Ice Age people lived high in the Andes 12,400 years ago
Ice Age people were able to survive at high elevations in the Peruvian Andes 12,400 years ago, almost a millennium earlier than previously thought, researchers have said.

Ice Age people were able to survive at high elevations in the Peruvian Andes 12,400 years ago, almost a millennium earlier than previously thought, researchers have said.
Hunter-gatherers made their homes at an elevation of 4,500 metres above sea level despite low oxygen, frigid weather and high solar radiation.
The discovery of tools, a rock shelter and human and animal bones at the Pucuncho archaeological site suggests that these people climbed high to settle down within 2,000 years of humans' arrival in South America.
"The Pucuncho Basin sites suggest that Pleistocene humans lived successfully at extreme high altitude," said the study in the US journal .
Experts still do not know if the people came to the area already well-equipped to handle extreme high altitudes, or if they evolved the traits necessary to survive and thrive.
