We have all heard about human diversity and also that evolution happened during years, but according to new findings the diversity of hominin species could be still bigger. Some Chinese and Spanish researchers have found a new piece for the complex human
evolution puzzle. The remains found in Xujiayao (China) are composed of an infant maxilar and some teeth of a still unclassifiable human species. This species would have inhabited in Asia about 60.000 and 120.000 years ago according to the American Journal of Physical Anthropology.

The dental morphology of the still not described hominid s
hows that the species shared features with Neanderthals (Homo neanderthalensis) and with the most primitive Asiatic Homo erectus, but they do not have any relationship with our species, the Homo sapiens. Taking this into account, researches proposed that this hominid would have coexisted with Neanderthals and modern humans in the late Pleistocene.

María Martinón-Torres, the coauthor of the study, has noticed that the taxonomy of many of the fossils found in the Asiatic continent should be reconsidered because those could be related with the newly found remains.
