Hypothesis

What are the morphological affinities and chronological age of the Iwo Eleru calvaria?

Conclusion

The Iwo Eleru cranium shows a mix of archaic and modern human features and dates to the terminal Pleistocene.

Supporting Evidence

  • The Iwo Eleru burial is one of the few human skeletal remains associated with Later Stone Age artifacts in West Africa.
  • Uranium-series dating suggests a terminal Pleistocene age for the Iwo Eleru burial.
  • The morphological analysis indicates a similarity with late archaic African specimens.

Takeaway

Scientists studied an ancient skull from Nigeria and found it has features of both early humans and modern humans, suggesting a complex history of human evolution.

Methodology

A 3-D geometric morphometric analysis and Uranium-series dating were conducted on the Iwo Eleru calvaria.

Limitations

The study is limited by the scarcity of human skeletal remains from the Later Stone Age in Africa.
