ELI5: What's the difference between Bulls, Bison, Buffalos, and Oxen? Are they all related to "normal" black and white cows?
gpt
A bull is a male cow.

A bison is a species related to cows that is native to North America.

A buffalo is one of many species related to cows native to Africa or Asia.

And unlike *every other post here, get it together people,* an ox is a job description, not a species. They are the same species as the "normal" cow or bull, just trained to do labor instead of be meat or milk suppliers. Not to be confused with a musk ox, which is not that closely related.
