All these fossils were a little older and a little more primitive than Au. afarensis, but judging from a shinbone found in Kenya and a thighbone from Asa Issie, Au. anamensis was also a biped. Indeed, there is general agreement—a rarity in paleoanthropology—that the chief difference between the two species is merely the passage of time. In other words, the names represent two arbitrary points in a single evolving lineage, with no clear dividing line between them.None of the researchers had dared to think it at first, but it was clear they had found the skeleton of a single individual as complete as Lucy but unlike her or anything else that had ever been seen. While most of the other bones at the site showed signs of being ravaged by hyenas after death, the hominid skeleton was miraculously untouched. After the female died, her remains apparently were trampled down into mud by passing hippos or other herbivores and protected from scavengers. After being buried for 4.4 million years, another year or two on the surface would have turned them all to dust.But he has also drawn accusations of ducking other elite runners and undermining the spirit of head-to-head competition.
