We review the fossil and genetic evidence that relate to evolution in the genus Homo. We focus on the origin of Homo and on the evidence for taxonomic diversity at the beginning of the evolutionary history of Homo and in the last 200,000 years. We set out the arguments for recognizing a second early Homo taxon, Homo rudolfensis, and the arguments for and against including Homo habilis sensu stricto and Homo rudolfensis within Homo. We end by reviewing recent genomic evolution within Homo. The challenge of the upcoming decades is to meld innovations in molecular genetic methods and technology with evidence from the fossil record to generate hypotheses about the developmental bases of the phenotypic and behavioral developments we see within the genus Homo.
