所有美洲大陆的原住土著居民,也就是各支印第安人都属黄种人。黄种人分为五大分支,即分为五大亚人种,印第安人属其中一支:美洲亚人种。印第安人的祖先大约是在近20000年前,跨过白令海峡从亚洲迁徙到北美,然后散布整个南北美洲大陆。
All the original inhabitants of the American continent, that is, the various branches of Indians, belong to the yellow race. The yellow race is divided into five major branches, that is, five major sub-races, and Indians belong to one of them: the American sub-race. The ancestors of the Indians migrated from Asia to North America across the Bering Strait about 20,000 years ago, and then spread throughout the North and South American continents.
