773,000-Year-Old Moroccan Fossils Illuminate Early Human Evolution
Newly analyzed fossils from Morocco, dated to 773,000 years ago, provide insights into the early divergence of human lineages.
Fossils unearthed at Thomas Quarry I near Casablanca, Morocco, have been precisely dated to approximately 773,000 years ago, offering valuable insights into early human evolution. The remains, including partial mandibles, teeth, and vertebrae, exhibit a combination of archaic and more modern traits, suggesting they belong to a population near the divergence point of Homo sapiens, Neanderthals, and Denisovans.
The dating was achieved through high-resolution magnetostratigraphic analysis, capturing the Matuyama–Brunhes geomagnetic reversal, a global event that occurred around 773,000 years ago. This precise dating places the Moroccan fossils contemporaneously with Homo antecessor remains found in Spain, yet morphological differences indicate regional differentiation between North Africa and Europe during the late Early Pleistocene.
The discovery underscores the significance of North Africa in early human evolution, reinforcing the view of an African origin for Homo sapiens. The findings have been published in the journal Nature.
