[QUOTE="inyati13, post: 1015378, member: 17767"] Thanks for that. You mentioned your theory that Bison and cattle are the same species or were the same species until they developed different traits. That is likely, as most Bovidae all have a common ancestor in their evolutionary history. That is how species originate. For example, if a population of animals are separated by a physical barrier into two separate populations that cannot reproduce with each other, they eventually become two separate species due to the isolation of their genetic pools. The Bison on Rocky Mtn Arsenal are [i]Bison bison[/i]; domestic cattle are [i]Bos premigenius[/i]. PS BTW, those Bison that were introduced on the Rocky Mtn Arsenal near Denver (Commerce City, to be exact) were put there with the idea in mind to provide another population of the pure Bison should a disease hit the herd on the National Bison Refuge. I also saw above that someone mentioned the bison being pure at Yellowstone. There may be some that are pure but many are contaminated due to mixing with the cattle herds that graze near the park. In fact, Montana at one time would allow you to kill bison in a seasonal hunt that ranged off the park. There was a concern among ranchers that the bison would carry brucellosis to their cattle. The hunt was ended because of the bad press it was getting from animal groups. [/QUOTE]
