Origins of the Ainu
by Gary Crawford
The ringing telephone broke the evening silence. It was the fall of 1983, and my research partner, Professor Masakazu Yoshizaki, was calling from Japan.
"Gary, I have some news," Yoshi said. "We have a few grains of barley from a site on the Hokkaido University campus. I think you should come and look at them."
The Japanese language is notorious for its ambiguity, so I wasn't quite sure of the full meaning of what I had just heard. But I didn't need to know much more. Though it may sound like a trivial piece of news to you, I knew something was up, and it deserved closer scrutiny. My teaching schedule at the University of Toronto kept me from hopping on a plane for several months, but when I finally got to the lab on Hokkaido, the northernmost island of Japan, I realized the full import of Yoshi's news - namely, that the history of Hokkaido's indigenous people, the Ainu, was about to be rewritten.
Since the mid-1970s I had been investigating the relationship between plants and people in prehistoric northeastern Japan, particularly Hokkaido, using an archeological tool called flotation. The widespread use of this technique beginning in the 1960s sparked a quiet revolution in archeology. Flotation facilitates the collection of plant remains, mainly seeds and charcoal, preserved by burning in oxygen-poor environments such as the depths of a fireplace. Under these circumstances, seeds don't oxidize to ashy dust. One can recover the resulting carbonized seeds by sampling soil from ancient hearths, floors, pits, garbage dumps, and the like. One places the soil gently in water, stirs it so the carbonized material floats to the surface, and then decants the water and its floating contents through a fine mesh, which traps the floating plant material while allowing the water to pass through.

Findings by American anthropologist C. Loring Brace, University of Michigan, will surely be controversial in race conscious Japan. The eye of the predicted storm will be the Ainu, a "racially different" group of some 18,000 people now living on the northern island of Hokkaido. Pure-blooded Ainu are easy to spot: they have lighter skin, more body hair, and higher-bridged noses than most Japanese. Most Japanese tend to look down on the Ainu.
Brace has studied the skeletons of about 1,100 Japanese, Ainu, and other Asian ethnic groups and has concluded that the revered samurai of Japan are actually descendants of the Ainu, not of the Yayoi from whom most modern Japanese are descended. In fact, Brace threw more fuel on the fire with:
"Dr. Brace said this interpretation also explains why the facial features of the Japanese ruling class are so often unlike those of typical modern Japanese. The Ainu-related samurai achieved such power and prestige in medieval Japan that they intermarried with royality and nobility, passing on Jomon-Ainu blood in the upper classes, while other Japanese were primarily descended from the Yoyoi." The reactions of Japanese scientists have been muted so. One Japanese anthropologist did say to Brace," I hope you are wrong."
The Ainu and their origin have always been rather mysterious, with some people claiming that the Ainu are really Caucasian or proto-Caucasian - in other words, "white." At present, Brace's study denies this interpretation.
