How do the new fossils change our understanding of human evolution?
The fossils from Morocco show a blend of primitive and modern features, indicating a complex evolution of early humans. They suggest that Homo erectus was more diverse than previously thought and may have been closer to the last common ancestor of modern humans, Neanderthals, and Denisovans.

Why is the age of 773,000 years important?
This age places the fossils at a critical point in human evolution, helping scientists refine timelines of when different human species emerged and diverged. It also provides evidence that early Homo erectus was present in North Africa during this period, influencing theories about migration and adaptation.

What does this discovery tell us about early human migration?
The Moroccan fossils suggest that early humans were already spreading across Africa over 770,000 years ago. This supports the idea that Africa was a key hub for human evolution and migration, with populations moving and evolving in different regions.
-
How do these fossils connect to other ancient human sites?
The fossils are similar in age to other important sites like Jebel Irhoud in Morocco and Gran Dolina in Spain. Together, these sites help build a more complete picture of human evolution, showing how different populations may have interacted or evolved separately across Africa and Eurasia.

What techniques did scientists use to analyze these fossils?
Researchers used advanced imaging techniques like micro-CT scans and geometric morphometry to study the fossils in detail. These methods allow scientists to examine tiny features and compare them with other ancient remains, providing insights into the physical traits and evolutionary relationships of early humans.
