Figure 2.
The paleobiological context for the evolution of modern humans. This diagram shows the general pattern for the evolution of Homo.Time is on the vertical axis, and the horizontal dimension is a representation of space, with Africa (middle), Europe (left), and Asia (right). The width of each band (very roughly) represents population size. The major population divergences (speciation events) are shown, with their associated technological systems. Generally speaking, the estimated coalescence points of genes will predate the actual population divergences shown in the paleontologically based estimates here.
