This would represent a level of care and concern rarely seen in other apes and monkeys although occasional reports of animal midwifery have been received. But in no animal species is midwifery as widespread as it is in humans. But there is another aspect of human birthing which sets us apart. That is the relation between mother and infant. The origin of bipedalism altered the way infants were cared for.
Chimpanzees have hands and feet which are capable of grasping objects.
The opposability of the chimpanzee big toe is great enough that the chimpanzee infant can hold onto the fur of its mother by means of four attachment points-both hands and both feet. The carrier of the infant chimp has no need to use her own hands and can walk around in a normal chimpanzee fashion. But this may have been different with Australopithecus . Australopithecus possessed a foot which was evolved for bipedal locomotion. While it was not exactly identical with modern human feet, it did not have an opposable big toe.
