Homo luzonensis at Callao Cave

Record summary

Researchers described Homo luzonensis from teeth and foot, hand and thigh bones found at Callao Cave. Its combination of small-bodied and unusual anatomical traits provides a major comparison point for island evolution, dispersal across Southeast Asia and the diversity of late Pleistocene hominins. The species is represented by fragmentary material, and its precise evolutionary relationship to Homo floresiensis, Homo erectus and modern humans remains debated. Direct evidence for how it reached Luzon is absent because no secure land bridge connected the island to mainland Asia during the relevant period.
