@Victor_Emmanuel @nugger @JSDorn @Tripp @matrix @nerdman i dont actually think this is the case at all - they domesticated horses, why not bison? because it was really fucking difficult if you were motivated to begin with, and they werent motivated. Humans all over the planet domesticated whatever animals they practically could, when they could. The point you brought up about wolves actually is very cogent - wolves are domesticated because (like horses) they have a family and hierarchical structure. Replace the top animal with yourself and you're well on your way to taming and then domestication generations down the line. This is not the case with either cows or bison, you never would hear the phrase "alpha bull" for a reason. heres a study from the american journal of dairy science (for whatever quality you give that) on cow family structure - namely the lack thereof.
journalofdairyscience.org/article/S0022-0302(68)86977-2/pdfAs for bison they are the same, but much larger - see pic related. Slower technological development, nomadic lifestyle, possibly religion, and lack of outside pressures on top of that are why the bison wasnt domesticated. If you REALLY want to push this for whatever reason, presumably to say that bison were domesticatable before, just that the indians were too inferior to actually do it, by all means continue. I dont think that's an accurate assessment though
And to be fair, most of the deaths caused by yuropooreans in the americas was because of viruses and bacteria, which they had no fucking clue of at the time.
Well at least not like in 1500s time. I think that by the time USA gave small pox blankets to indians they kinda knew.
