Abstract
With the advent of computational genomics, an intensive search is underway for unique biomarkers for Homo sapiens that could be used to differentiate taxa within the Hominoidea, in particular to distinguish Homo from the apes (Pan, Gorilla, Pongo, and Hylobates) and species or subspecies within the genus Homo (H. sapiens, H. heidelbergensis, H. neanderthalensis, H. erectus, and the Denisovans). Here, we suggest that the |-FAM72–SRGAP2-| (family with sequence similarity 72/SLIT-ROBO Rho GTPase activating protein 2) gene pair is a unique molecular biomarker for the genus Homo that could also help to place Australopithecus at its most appropriate place within the phylogenetic tree and may explain the distinctive higher brain cognitive functions of humans.
