Scientifically Acceptable Fossil Footprints
Mary Leakey has announced the discovery of fossil footprints made by prehuman ancestors more than 3.5 million years ago at Laetolil, 25 miles southwest of Olduvai Gorge in Tanzania. The hominoid had apparently walked across slightly moist sand, and the prints were soon filled with volcanic ash. The prints were made by feet shorter and wider than those of modern humans; but the big toe definitely points forward and is not splayed as in apes.
