Yakalo
Yaks can also mate with American bison to produce yakalos as their offspring. These two species do not interact with each other in the wild, therefore it is clear that yakalos do not occur naturally. In fact, these animals were produced by scientists in the 1920s as a part of an experimental project regarding hybridization.
These animals were produced using either pure bison or, for the most part, using beefalos (which we learned about earlier!). The heads of these animals resemble those of bison while their remaining body has a mix of bison and yak appearance. Unfortunately, the experiments surrounding these hybrids were not very successful and were abandoned.
