He finds near kinsmen for them in the Ainus of Japan, the Khmers and Chams of Cambodia and among some of the Micronesian islanders who, in spite of much crossing, still exhibit marked Caucasic types.
In the Micronesian Islands, while animism and tabu were strong, there was not the cannibalism of the southern islands.
The Micronesian islanders form in the main a branch of the Polynesian race, but distinguished from it by well-marked differences in appearance, language and institutions.
The natives, who are Micronesian hybrids of finer physique than their kinsmen of the Pelew Islands, have a comparatively high mental standard, being careful agriculturists, and peculiarly clever boatbuilders and navigators.
The general Micronesian type is a well-proportioned rather slightly built figure, with small and regular features; head high and well proportioned, but forehead rather retreating and narrow at the temples; cheek bones and chin slightly prominent; straight black hair, lanker than that of the Polynesians, colour somewhat darker than the Polynesians, the Marshalls being darker and more vigorous than the Carolines, while the Gilbert type, though smaller than the latter, is still darker and coarser.
The latest theory, however, is that there is a great linguistic group (which may or may not prove to correspond to an ethnic unity) comprising the Munda, Monkhmer, Malay, Polynesian and Micronesian languages, and that the stream of immigration which distributed them started from the extreme west.
