Breakthrough in Human's Evolutionary History
Science has published a 17-year study of the oldest known skeleton of a putative human ancestor, widening the evolutionary gap between humans and chimps.
40+ researchers from 11 countries studied Ardipithecus ramidus, and discovered it had a brain and body like a chimpanzee, had hands much more like a human than a chimp or ape, and walked upright. The find is incredible as scientists had anticipated the ancestors of humans to be an intermediary between a chimp (man's closest genetic cousin) and man. This means that as of now, science believes man and chimps common ancestor was neither human, nor chimpanzee, but a distinct, separate species from which apes, chimps, and humans evolved.
