Humans survived off rodents in the mountains during the last ice age, study says

edition.cnn.com
  • 45,000 years ago, during the Paleoithic era, some humans settled in the Bale Mountains (~4,000 meters) to survive the last ice age.
  • This shows that humans started living at high altitudes much earlier than previously believed.
  • Melting glaciers gave them water, and they hunted giant mole rats with obsidian tools.
  • The discovery might be an explanation for why some people living in Ethiopia today are able to prosper in low oxygen levels.
