Some New Facts on Early Human Evo-Devo

Standard
  • Modern humans and Neanderthals diverged 550,000-765,000 years ago.

  • Neanderthals and Denisovans diverged 381,000-473,000 years ago.
  • Modern humans mated with Neanderthals in Asia around 100,000 years ago, during our first failed wave of migration, leaving our genes in their DNA.
  • Modern humans mated with Neanderthals in the middle East around 50,000 years ago, during the second successful wave of migration. We got some of their DNA, which has been linked with a number of characteristics.
  • Modern humans mated with Denisovans in Central and Eastern Asia, and got some cool genes from them, including one that enables Tibetans to live at high altitude.
  • Denisovans mated with an unknown form (NB we don’t know what the Denisovans looked like, beyond the fact that they had whopping teeth), perhaps a relict Homo erectus, the product of the very first wave of Homo migration from Africa
