Dec. 5, 2013 — A human ancestor characterized by "robust" jaw and skull bones was a muscular creature with a gorilla-like upper body and more adaptive to its environment than previously thought, scientists have discovered.
Researchers found a partial skeleton -- including arm, hand, leg and foot fragments -- dated to 1.34 million years old and belonging to Paranthropus boisei at the Olduvai Gorge World Heritage fossil site in Tanzania. The find, published in the latest edition of the scientific journal PLOS ONE, represents one of the most recent occurrences of P. boisei before its extinction in East Africa.
