An article published in the journal “Nature” reports the recognition of a new species of primitive humans that was named Homo luzonensis. A team of researchers studied a number of fossils discovered between 2007 and 2015 in Callao Cave, on the island of Luzon, Philippines, concluding that these are the remains of individuals belonging to a species of hominins different from those hitherto known who lived on the island between 50,000 and 67,000 years ago.
