When did hyaena brunnea first appear in the African grassland? Did European immigrants bring it to Africa or did it exist a long time ago?

Hyenas were originally distributed in Asia and Africa tens of thousands of years ago. At present, scientific research cannot determine the specific age.

Hyaena brunnea is mainly distributed in the open areas of sub-Saharan Africa, except tropical rain forest areas.

In fact, the hyena once spread all over China, but it became extinct in China and even Eurasia ten thousand years ago. At present, many Africans keep spotted hyenas as pets.
