The article is about the discovery of fossils of a new species found in a cave in South Africa, known as Australopithecus sediba. Lee Berger, the person who discovered the fossils, says that the species is “the most plausible known ancestor of archaic and modern humans.” Some paleanthropologists disagreee, but if Berger’s claim is accepted, this discovery could change the present version of the human family tree. This is significant because the fossils of Australopithecus sediba could clear up uncertainties regarding exactly when the human lineage emerged.

I agree how Australopithecus sediba could clear up uncertainties about the human lineage. The fossils are old. This can lead to knowing more about another bipedal that lived. Research on this fossil can help us know about the fossils' past. With the fossils, scientists may find out about how they walk. These could connect with primates.
I think this is super interesting because even the smallest fossils we find help us put the pieces together. This discovery had a big impact on the human family tree and could possibly change it.
