Morotopithecus bishopi is a species of fossil ape discovered in Moroto, Uganda.[1] According to Molecular data, the split between apes and Old World monkeys occurred around 23 million years ago at the start of the Miocene. The first true hominoids occurred during the early Miocene around 20 million years ago in East Africa. This includes the genus Morotopithecus. Morotopithecus were arboreal forms living in primarily forested habitats, had bunodont molars suggesting a frugivorous diet, and were more derived than the generalized ape-like forms of the Fayum Formation (such as Aegyptopithecus): for example, like all apes, they lacked a tail. Morotopithecus was the size of a small human and is the first hominoid to have derived features of skeletal anatomy showing capacity for suspensory locomotion. These features include a highly mobile shoulder joint, a short stiff back resisting lumbar flexion, and a moderately mobile hip joint.[2]
For a variety of reasons, the term “human” has been applied to a clade of hominoids commencing at the split from the Chimpanzee lineage about six million years ago. The basis for this distinction has been upright bipedalism exclusively in the human lineage. However, when the evidence from serial axial structures and homeotic events are considered, the anatomical basis for upright posture and bipedalism appears to have arisen far earlier–it is the axial anatomy first seen in Morotopithecus. Upright bipedalism plays a significant role in all the species of a clade that share the morphogenetic transformation with Morotopithecus.[3]
