One of the most contentious topics in the study of human evolution is
that of the time, place and mode of origin of Homo sapiens(1-3). The d
iscovery in the Northern Danakil (Afar) Depression, Eritrea, of a well
-preserved Homo cranium with a mixture of characters typical of H. ere
ctus and H. sapiens contributes significantly to this debate. The cran
ium was found in a succession of fluvio-deltaic and lacustrine deposit
s and is associated with a rich mammalian fauna of early to early-midd
le Pleistocene age. A magnetostratigraphic survey indicates two revers
ed and two normal magnetozones. The layer in which the cranium was fou
nd is near the top of the lower normal magnetozone, which is identifie
d as the Jaramillo subchron. Consequently, the human remains can be da
ted at similar to 1 million years before present.
