H. Luzonensis: A Polemic Finding (at Least 67,000 Years Ago)

In 2019, researchers visited a small cave on an island in northern Indonesia. Inspired by the discovery of H. floresiensis, the scientists wondered whether other islands also had human dwellers. The researchers struck gold — kind of. Though they found human remains, they only unearthed seven teeth, three foot bones, two finger bones, and a fragment of a thighbone. Still, due to its geographic isolation and small size, the scientists felt confident in declaring that this species was unknown to science. They named it luzonensis after Luzon, the island on which it was found.
