Modern human brain originated in Africa around 1.7 million years ago


Sumary of Modern human brain originated in Africa around 1.7 million years ago:

  • These earliest Homo populations in Africa had primitive ape-like brains — just like their extinct ancestors, the australopithecines..
  • An international team led by Christoph Zollikofer and Marcia Ponce de León from the Department of Anthropology at the University of Zurich (UZH) has now succeeded in answering these questions..
  • “Our analyses suggest that modern human brain structures emerged only 1.5 to 1.7 million years ago in African Homo populations,”.
  • Apart from the size, the human brain differs from that of the great apes particularly in the location and organization of individual brain regions..
  • “The features typical to humans are primarily those regions in the frontal lobe that are responsible for planning and executing complex patterns of thought and action, and ultimately also for language,”.
  • Since these areas are significantly larger in the human brain, the adjacent brain regions shifted further back..
  • The first Homo populations outside Africa — in Dmanisi in what is now Georgia — had brains that were just as primitive as their African relatives..
  • It follows, therefore, that the brains of early humans did not become particularly large or particularly modern until around 1.7 million years ago..
  • However, these early humans were quite capable of making numerous tools, adapting to the new environmental conditions of Eurasia, developing animal food sources, and caring for group members in need of help….
