Pinza-Abu remains dated 30,000 years ago. Occipital squama shows larger sagittal arcs than modern Japanese. Parietal sagittal dimensions much smaller than modern Japanese like Minatogawa skulls. Vertebra smaller than recent Japanese vertebrae but matches Minatogawa Man. Shares archaic physical features with Minatogawa Man from Ryukyu Islands. Suggests close biological relationship between Pinza-Abu and Minatogawa people. Possible origin from Malaysia due to Wadjak Man similarities. Speculated as descendant of Java Man. Java Man fire-making implies Pinza-Abu had similar skills. Charcoal found with remains confirms possible fire use. Stone tools found indicating tool-making adeptness. Hunted deer and boar in small familial groups. Lacked large mammals forcing individual or small-group hunting. Fauna from Late Pleistocene now extinct on Miyako Island. No evidence linking Pinza-Abu as ancestors of modern Miyako Islanders.
