Why Blue Eyes Come From One Ancestor
Blue eyes are one of the rarest and most instantly recognizable traits in the world. Yet scientists now believe that every person with blue eyes can be traced back to a single ancient ancestor. In this documentary style episode, we explore the genetic mutation that first created blue eyes, how it spread across Europe, and why it survived.
Using ancient DNA, anthropology, and evolutionary biology, this video uncovers the surprising history behind one of humanity’s most iconic traits.
If you love genetics, ancestry, and the story of human evolution, this deep dive reveals how one change in our DNA shaped millions of people today.
