2. The fossil record suggests that the major transitions in human evolution occurred in Africa:
The first hominins, the first members of the genus Homo, and the first members of our
subspecies (Homo sapiens sapiens) all are found there.
A. Please assign approximate dates to these three transitions.
B. There were at least three major dispersals of hominins from Africa: some early members of
the genus Homo (probably H. ergaster) about 1.75 million years ago, H. heidelbergensis roughly
one million years later and, most recently, Homo sapiens sapiens about 70 thousand years ago.
Did the entire population of Homo sapiens sapiens leave Africa at that time? If not, are there
identifiable lineages that stayed in Africa?
C. What happened when Homo sapiens sapiens left Africa, and what is the evidence that
supports that interpretation..
