umans will not occur in the distant future. Scientists dismiss the idea that the species is “going somewhere” under natural selection and then describe how most successful species are stable through their geological lifetimes. Furthermore, given the relative pace of cultural change and lack of isolation of human populations, there is little chance for a new different human species. Modern understanding of human evolution rests on known fossils, but the picture is far from complete. Only future fossil discoveries will enable scientists to fill many of the blanks in the present picture of human evolution. Employing sophisticated technological devices as well as the accumulated knowledge of the patterns of geological deposition, anthropologists are now able to pinpoint the most promising locations for fossil hunting more accurately. In the years ahead this will result in an enormous increase in the understanding of human biological history....
