Hominin: A human or extinct species more closely related to humans than to chimpanzees. Penghu 1 is a fossil of an archaic member of the human evolutionary lineage.
Molar: A broad, rear tooth specialized for grinding food. The size and shape of Penghu 1’s molars are central to its anatomical distinctiveness.
Homo floresiensis: An extinct small-bodied human species known from fossils on the Indonesian island of Flores. Its discovery helped renew debate about unexpected archaic human lineages in Southeast Asia.
Homo erectus: An extinct human species that lived across Africa and Asia for much of the Pleistocene. Some researchers have considered whether Penghu 1 belongs within this widespread species.
Mandible: The lower jawbone, which holds the lower teeth and forms the movable part of the jaw. The fossil’s identity and classification rest on features of this bone.
Dental morphology: The study of tooth form, including cusp patterns, size, and wear. Tooth traits help compare the fossil with other extinct Homo populations.
Homo luzonensis: An extinct human species identified from fossils in Callao Cave on the Philippine island of Luzon. It provides another case of a distinctive archaic human population in Island Southeast Asia.
Homo heidelbergensis: An extinct human species or species group associated with the Middle Pleistocene. Its broad and contested use highlights the taxonomic uncertainty surrounding archaic fossils.
Homo: A genus of hominins that includes modern humans and several extinct human species. Penghu 1 has been attributed to an archaic lineage within this genus.
Comparative anatomy: The analysis of anatomical similarities and differences among organisms. Researchers assess Penghu 1 by comparing its jaw and teeth with other fossils.
