Researchers have recently uncovered the bones of a new human species from the Callao Caves in the Philippines. On unearthing the cave, they have uncovered more bones and seven teeth of humans dated 50,000 years. Researchers have classified their features as an unusual combination of ancient and modern human species and labeled them as Homo Luzonensis. The new human species have made the family tree of human evolution even more complicated and forced the researchers to analyze the role of southeast asia in human evolution.
