The finding is a real blow to the idea that bipedalism equals ‘ape-man’. I.e., if apes/primates in Europe (and there are now several, e.g. Danuvius guggenmosi, Rudapithecus hungaricus and Oreopithecus bambolii) were built for some form of bipedalism, yet are not regarded as ape-men, then why would bipedal features in the australopiths from Africa mean they were ape-men?
On the locomotion of D. guggenmosi, Kivell wrote that the authors interpreted the shape of the “fossils as indicating a type of previously unknown movement that they term extended limb clambering, which combines adaptations of both suspension in the trees and bipedal locomotion.” Today’s orangutans can also move bipedally in trees, though not habitually. Thus, the ability to walk bipedally (though not necessarily in the same way as humans) appears to have been a useful designed method of movement for some extinct tree-dwelling primates." CMI
