  1. 1

    As recently as 50,000 years ago, humans shared the planet with at least three other human species, including Denisovans and Neanderthals.

  2. 2

    Neanderthals were adapted to cold northern climates, and evidence suggests they were caring and social, even burying their dead and caring for the sick.

  3. 3

    Modern humans share 1 to 4 percent of their genes with Neanderthals, indicating that the two species interbred after humans left Africa.
