The Human Origin Story Is Being Radically Revised Our understanding of human history is undergoing a significant transformation as recent archaeological discoveries challenge long held assumptions about the development of complex tools, early migrations, and even our own identity.
Research published in Science suggests that other hominins may have played a more significant role than previously thought in tool development.
The study points to two "ghost" ancestors: one that mated with humans before they left Africa and another linked to Homo erectus , which wandered out of Africa nearly 2 million years ago.
