bovid
American bison, or plains buffalo (Bison bison).
During the Pleistocene Epoch, several bovid groups evolved specific adaptations to survive in cold northern climates. These groups include:
- Caprinae: This subfamily includes goats, sheep, goat antelopes, and musk oxen.1
- Bovines: This group includes the yak, bison, and the extinct aurochs, which was the ancestor of domestic cattle.1
- Gazelle tribe (Antilopini): Certain members of this tribe, such as the Mongolian gazelle, also adapted to these cooler environments.1
These bovids developed various physiological and behavioral traits to thrive in harsh, cold conditions, often utilizing their ability to efficiently extract nutrients from fibrous diets to survive in ecosystems with limited resources. For example, the musk ox is particularly well-equipped for extreme cold due to its exceptionally thick coat.12
