Is Buffalo’s natural fear of humans caused by shared generational trauma/ evolution?

My husband and I live near Prairie State Park in Missouri (you should totally go if you can, it’s really a gem in the middle of nowhere). I told him we need to go camping out there next summer, and added (as a joke) “I wanna get high and pet a buffalo” (DO NOT attempt to pet the Buffalo. Not a joke- do not approach the buffalo if you do go out there). My husband said I could try but it would end badly. Which lead to a conversation about Buffalo’s distrust of humans. Which leads me to my question:

Do you think Buffalo/ Bison are so terrified of humans because we over hunted them and almost caused them to go extinct? Is this some kind of shared generational trauma bison suffer due to over hunting?
