3.6-Million-Year-Old Preserved Hominid Footprints at Risk of Obliteration by Climate Change
Human history stretches back millions of years to Africa, where early species of hominids roamed and eventually evolved into modern-day Homo sapiens. Our family tree includes many species now long extinct which formed steps or branches of the evolutionary tree descending into modernity. One very early ancestor of mankind was Australopithecus afarensis, who roamed eastern Africa about 2.95 to 3.85 million years ago.
