New Species of Hominin Found in Phillipines

From a story in UPI:

At the completion of excavations on the island of Luzon, scientists had unearthed several teeth, part of a thigh bone, and a few hand and foot bones. The fossils comprise the “the earliest direct evidence of a human presence in the Philippines,” according to the latest study.

The fossilized bones, dated to between 67,000 and 50,000 years ago, feature a mix of anatomical characteristics, some that recall more primitive hominins and others similar to those of more modern human species.

Callao Cave is toward the northern tip of Luzon. The corresponding article from Nature seems to indicate that the fossil remains from this cave are “all over the map.”  The premolars indicate size and shape affinities to later Homo, while some of the characteristics are australopithecine (!).  This is also true of the hand elements. 

Although we have found human fossil remains in East Asia for some time (1896 on), there are large gaps in our knowledge, especially from the first appearance of Homo erectus to the advent of modern humans.  These fossils, while giving us more  information than we had, muddy the waters a bit.  Once upon a time, Grover Kranz (RIP) tried to convince me that australopithecines could be found in East Asia, but his evidence was based on a badly crushed occipital bone. 

It is clear from the presence of H. floresiensis and the current evidence that primitive traits were being retained in some groups but, as the authors point out, we need quite a bit more fossil material to make any definitive assessments.
