查了一下，有關係。至少缺一個智齒：非裔11%，歐裔10-25%，亞裔40%，因紐特人45% 。

"Perhaps 10 to 25 percent of Americans of European ancestry are missing at least one third molar, Mann said. For African Americans and Asian Americans, the figure is 11 percent and 40 percent, respectively, he said. But the Inuit, a group of people who live in the Arctic regions of Canada, Greenland and Alaska, have the fewest wisdom teeth; about 45 percent of them lack one or more third molar, he said."

• 與蒙古人關係較近，與北方人也不遠。他們的祖先是從西伯利亞穿越白令海橋，追著猛獁象過去的。。。 -吃與活- ♂ (0 bytes) () 05/23/2016 postreply 11:30:52
