Partial Skeletons Found in South African May Represent New Hominid

From Science Times:

Nearly two million years ago, an adult and a child walking through the South African landscape somehow fell through openings in a partly eroded, underground cave and died. Today, that fatal plunge has led to their identification as representatives of a new hominid species — and a contentious debate among paleoanthropologists over the pair’s evolutionary relationship to modern humans.

In the April 9 Science, anthropologist Lee Berger of the University of the Witwatersrand in Johannesburg and his colleagues assign newly discovered fossils from these ancient individuals to the species Australopithecus sediba. They propose that the species served as an evolutionary bridge from apelike members of Australopithecus to the Homo genus, which includes living people. In a local African tongue, sediba means fountain or wellspring, a reference to this species as a candidate ancestor of the Homo line.“Australopithecus sediba could be a Rosetta Stone for anatomically defining the Homo genus,” Berger says.
