New Homo floresiensis remains have been found, making the claim of microcephaly even more unlikely than before. But the new species may not be part of the genus Homo; it´s more likely a remnant of the Australopithecines. More.
The Australopithecine hominid lineage rose at least 4,2 million years ago, most likely from the Ardipithecus lineage. About 3 million years ago it split into two branches, the first leading most likely to the genus Homo around 2,3 million years ago, the second leading to the genus Paranthropus, which is though to have become extinct 1,1-1,2 million years ago. The new hominid species from the island of Flores is then a descendant of either the Paranthropus lineage or some earlier Australopithecine species.
