#D アイヌを含む北東アジア地域22集団の頭蓋について計測を行い、多変量解析を用いて形態の変異を調べた。その結果、アイヌは他の北東アジア集団と大きく異なる形態を持つ一方で、北東アジア集団内にもいくつかのグループが見られた。今回は、すでに報告した頭蓋形態小変異の分析結果ならびに遺伝学の成果を合わせながら、頭蓋計測の結果について、その意味や有用性を考察する。

#T The affinities of Northeast Asian populations were investigated using new
craniometric data. The three major groups of recent eastern Siberian
populations were analyzed. The Aleut show a close affinity with not only the
other Arctic peoples but also the Ainu. The Central Asian group consisting of
the Buryat, Mongolian and Yakut form a cluster, though the Yakut have some
unique characteristics. The Kazakh from Central Asia show similarities to the
other Central Asian peoples. The Baikal peoples form a loose cluster. The
Neolithic Baikalian cluster with the Evenki and Yukagir confirms the
continuity from the Neolithic Baikalian to the Baikal peoples. On the other
hand, the Troitskoe of the Mo-ho culture from the Amur basin show more
affinities with the inland peoples. The Ekven, the Iron age ancestors of the
Arctic peoples, are separated statistically from the recent Arctic populations
due to their hyperdolichocrany. In the multivariate analysis, the Hokkaido
Ainu differ from both Europeans and Northeast Asians, or ``classic
Mongoloids''. The Sakhalin Ainu have intermediate characteristics between the
Hokkaido Ainu and Northern Mongoloids.
