there are no races, race doesnt exist. but by us standards on race; there are the following: black(origins from sub sahara africa),white(origins from europe,north africa,saudi arabia,north indian),asian(east asians, indians,some pacific islanders),native(native americans,pacific islanders like hawaiian), and hispanic(not a race but us counts it as a culture or ethnicity .a mix of spanish people and native people and also some white and black. mexicans,peurtoricans,etc.)
of course indians are different from east asians, but the U.S. says different. the U.S. lumps tons of asian ethnicitys together.and every population has a distinct look thats why those negroid,mongoloid,etc terms dont exist anymore, thats why we dont classify rqce by a distinct look but rather by similarities because people are far distinct from another and it would be far more racial categories.....probably a few thousand
