Anthropologist Joseph Powell of the University of New Mexico was also allowed to examine the remains. Powell used craniometric data obtained by anthropologist William White Howells of Harvard University and anthropologist Tsunehiko Hanihara of Saga University; this had the advantage of including data drawn from Asian and North American populations. Powell said that Kennewick Man was not European but most resembled the Ainu and Polynesians. Powell said that the Ainu descend from the Jōmon people, an East Asian population with "closest biological affinity with south-east Asians rather than western Eurasian peoples". Powell said that dental analysis showed the skull to have a 94-percent consistency with being of a Sundadont group like the Ainu and Polynesians and only a 48-percent consistency with being of a Sinodont group like that of North Asia. Powell said analysis of the skull showed it to be "unlike American Indians and Europeans". Powell concluded that the remains were "clearly not a Caucasoid unless Ainu and Polynesians are considered Caucasoid".
