Ethiopian rock shelter earliest evidence of high-altitude prehistoric life

Archaeologists have discovered a rock shelter in Ethiopia dating back over 30,000 years, providing the earliest evidence of human habitation at high altitudes. The site, Fincha Habera, shows signs of Middle Stone Age foragers living and feasting on giant mole-rats at an elevation of over 11,000 feet.
