It may be the opposite, maybe the front ones lengthened to raise their heads even higher than their already long necks do. Striped hyenas are almost extinct in Central Asia, but animals have been spotted in Turkmenistan. Aardwolves resemble striped hyenas, with similar fur texture and color. Bones that show cut marks from early stone tools mixed with tooth marks of hyenas suggest hyenas were laughing at humans and stealing our dinner for as much as 2.5 million years. Spotted hyenas are the largest of the three. She is a passionate conservationist and founder of the Sloth Appreciation Society (www.slothville.com).

The list follows McKenna and Bell's Classification of Mammals for prehistoric genera (1997)[12] and Wozencraft (2005) in Wilson and Reeders Mammal Species of the World for extant genera. But survival is an unsentimental sport, and the hyenas hunting strategy is based on endurance. What they hunt depends on numbers. Aristocratic French naturalist Georges-Louis Leclerc, Comte deBuffon, dismissed the hyenas calls as simply sounding like the sobs or reachings of a man in a violent fit of vomiting.

The Protelinae (aardwolves) are not treated as a separate subfamily, but included in the Hyaeninae. [3], Although phylogenetically closer to felines and viverrids, as part of suborder Feliformia, hyenas are behaviourally and morphologically similar to canids in several elements due to convergent evolution: both hyenas and canines are non-arboreal, cursorial hunters that catch prey with their teeth rather than claws. The relative length of the limbs means almost nothing functionally, it is the relative length of the gait, or the distance the limbs can swing that is important, a longer less flexible limb may swing the same distance as a shorter but more flexible limb.
