If Bison were in contact with humans that had the cognitive ability to attempt domestication then yes they would have been.
Can you show the recorded attempts of the Native Americans to domesticate the Bison?
Considering it took until the latter half of the 20th Century for the American Bison to be widely domesticated and the fact that European settlers didn't domesticate the bison because they already had cattle and other livestock already brought over from Europe, so it wasn't really necessary.
The only reason why anyone even tried to domesticate bison was largely because of conservation efforts and trying to keep the species from going completely extinct.
Native Americans did domesticate the turkey, which is one of only three major domesticated animals originally from the Americas, the others being llamas and alpacas.
Things like advanced agriculture, the right kinds of livestock, and easier access to surface minerals such as iron, copper, and tin are crucial in the development of any worthwhile civilization. That's the primary reason why Europe, the Middle East, and East Asia succeeded while Sub-Saharan Africa largely floundered in terms of widespread technological and societal development.
Tellingly, the most developed and advanced parts of Sub-Saharan Africa prior to colonization were all near major trade routes, such as the Gold Coast or the Gulf of Aden.
Most of the problems with the African-American community are cultural due to a mix of poverty, political manipulation by major political parties, and the fact that mainstream society on both sides have deemed it completely verboten for anyone to actually question the toxic elements of Black culture (lest they be branded a racist or an Uncle Tom)
Tellingly, most Africans and Caribbean blacks (Jamaicans, Haitians, etc.) outright hate inner-city black Americans due to their uniquely toxic culture. And it's not just the "evil privileged whites" and East Asians (who are practically Honorary Whites in the eyes of SJW's) who have problems with the black community, a lot of Hispanics despise them and even many Native Americans tend to look down on blacks.
Seriously, I've visited a few reservations when I was on the road with my Dad, and apparently the locals hate black tourists a lot, but are fairly chill with white tourists (particularly older white tourists) since they tend to listen and be more respectful and actually spend money on the reservations, even if it's just to buy tacky souvenirs.
Race realism is utter bunk and anyone who actually believes in it is retarded. Culture is the real problem at hand and you can't judge entire countries and continents based on what their descendants in the United States are like.
Judging Africa because of what hood rats do is as dumb as judging Northern Ireland because of what hillbillies do.
