Continued work in this region by scientists from the Max Planck Institute for Evolutionary Anthropology, and an international team of collaborators, has revealed
a hominin trace fossil discovery of unprecedented scale for this time period — five distinct sites that preserve a total of 97 tracks created by at least 20 different presumed Homo erectus individuals.
«It's possible we'll one day find three groups of
hominin fossils — those with Gc - CS before the human lineage branched off, those without Gc - CS in our direct lineage, and then more recent
fossils in which
trace amounts of Gc - CS began to reappear when our ancestors began eating red meat,» Varki said.
