USA HISTORY

Detailed explanation-1: -Despite the massive amount of known Indigenous history and its being integral to the history of the US, most K-12 public schools relegate it to only a small portion of social studies; current educational standards place little importance on promoting understanding of Native Americans.

Detailed explanation-2: -These include the Arapaho, Assiniboine, Blackfoot, Cheyenne, Comanche, Crow, Gros Ventre, Kiowa, Lakota, Lipan, Plains Apache (or Kiowa Apache), Plains Cree, Plains Ojibwe, Sarsi, Nakoda (Stoney), and Tonkawa.

Detailed explanation-3: -The ACS codes 381 distinct non-English languages, and 169 of these are Native North American languages. Although Native North American languages make up most of the languages coded, the speakers of these languages number less than half a million.

Detailed explanation-4: -The linguistic diversity of native North Americans suggests, indeed, that the area was populated as a result of at least three, possibly several, separate waves of migration from Asia. The languages they brought with them, however, have no discernible relatives in Asia.
