Skull Fossil Challenges Out of Africa Theory

An exquisitely preserved skull of a tiny-brained human ancestor has been recovered from excavations beneath the ruins of a medieval castle in the republic of Georgia. The skull is about 1.8 million years old and belongs to the first group of humans to migrate out of Africa, reports an international team of archaeologists.

The find calls into question a widely held hypothesis that the evolution of big brains propelled the exodus of early humans out of Africa.
