It seems like you might be asking about the relationship between American bison and European bison (also called wisent). While they are both members of the same genus, *Bison*, they are different species.
Here's a breakdown:
* American bison (Bison bison): Found in North America, it's the larger of the two species and is known for its humped back and shaggy coat.
* European bison (Bison bonasus): Native to Europe, it's smaller than the American bison and has a more rounded back.
So, while related, American bison and European bison are distinct species.
