3.6 mn-yr-old early human footprints found in Tanzania
Footprints of five ancestors of humans who lived more than 3.6 million years ago have been discovered preserved in volcanic ash in Tanzania. They are believed to have belonged to three females, a male and a child from the Australopithecus species of walking apes. Analysis of the footprints have led scientists to infer that the male had multiple female mates.
