Kennewick Man's teeth reportedly match a dental pattern found today in South Asia.

Notes on verification

Wikipedia's Sinodonty/Sundadonty article provides solid academic grounding, but other cited sources (crystalinks, ancient-origins, forum post) are low-quality or popular-press. The core claim about Sundadont dental traits linking Kennewick Man to Southeast/South Asian populations is consistent with published anthropological research, though 'South Asia' is a loose simplification of the more precise 'Sundadont' classification tied to Southeast Asia/Pacific populations.
