Its front legs are longer than its back legs, giving the hyena a profile somewhat like that of a wildebeest or bison.

[6], Hyenas originated in the jungles of Miocene Eurasia 22million years ago, when most early feliform species were still largely arboreal. Adult females give birth to cubs in isolated dens and later move their cubs to kindergarten in communal dens, which are holes previously dug by other wildlife such as aardvarks. As fossil striped hyenas are absent from the Mediterranean region, it is likely that the species is a relatively late invader to Eurasia, having likely spread outside Africa only after the extinction of spotted hyenas in Asia at the end of the Ice Age.
