e/Pan prior

Information
has gloss	eng: Pan prior is the nomenclature suggested by British biological anthropologist Richard Wrangham for the common ancestor of humans (Homo sapiens) and chimpanzees (Pan troglodytes). This species is supposed, on the basis of DNA reconstruction (no fossil remains have been found), to have existed prior to six million years ago, when the human and chimpanzee lines are thought to have diverged. Pan prior lived an arboreal existence in the forests of Africa. When an Ice Age, around seven million years ago, caused the forests to shrink, some members of the species left the forests and ventured into the savannah, becoming the ancestors of humanity.
