Genetic and other evidence for human origins within Africa. Left panel: Y-chromosomal branches are those analyzed by Cruciani et al. [1]; also shown is a simplified version of the mitochondrial DNA tree [3]. In each case, 'Out of Africa' branches are in pale blue. Autosomal evidence is from Tishkoff et al. [5] and Henn et al. [6]. Right panel: approximate locations are shown for the earliest non-genetic evidence of modern humans within Africa (see text for references).
