Fossil fragments which were unearthed in Kenya a few years ago are thought to belong to two additional pre-human species living in Africa.
According to the study published in the Nature
journal, the findings suggest that at least three distinct species coexisted in Africa.
A team of anthropologists led by Meave Leakey found facial and jaw bones of three different creatures, believed to be about two million years old, at Koobi Fora, east of Lake Turkana, Kenya between 2007 and 2009.
“The three different species could have been living at the same time at the same place, but probably did not interact much,” said the study co-author Fred Spoor of the Max Planck Institute in Germany.
