Fossils discovered in Morocco, dating back more than 773,000 years, provide new evidence supporting the theory that Homo sapiens originated in Africa. These ancient remains, including a slender lower jawbone, fill a crucial gap in the African fossil record and help clarify the timeline of human evolution. By precisely dating the fossils to a period when Earth's magnetic field reversed, scientists have strengthened the case that the last common ancestor of modern humans and their cousins lived in Africa. The findings also suggest that the evolutionary divergence of our lineage may have begun earlier than previously thought, and hint at possible ancient connections between North Africa and Europe.
