We can thus hypothesize that the more developed anterior fascicle of the UCL in humans may be related to a more pronounced carrying angle in the upper limb and to the valgus forces acting on the elbow during manual tasks. In contrast, the larger LUCL in chimpanzees may help stabilize the elbow during arboreal locomotion and during the support phase of knuckle\u2010walking.<\/jats:p>\n
