Homo naledi, a new species of the genus Homo from the Dinaledi Chamber, South Africa

Homo naledi is a previously-unknown species of extinct hominin discovered within the Dinaledi Chamber of the Rising Star cave system, Cradle of Humankind, South Africa. This species is characterized by body mass and stature similar to small-bodied human populations but a small endocranial volume similar to australopiths. Cranial morphology of H. naledi is unique, but most similar to early Homo species including Homo erectus, Homo habilis or Homo rudolfensis. While primitive, the dentition is generally small and simple in occlusal morphology. H. naledi has humanlike manipulatory adaptations of the hand and wrist. It also exhibits a humanlike foot and lower limb. These humanlike aspects are contrasted in the postcrania with a more primitive or australopith-like trunk, shoulder, pelvis and proximal femur. Representing at least 15 individuals with most skeletal elements repeated multiple times, this is the largest assemblage of a single species of hominins yet discovered in Africa.

根据遗骨的形态和复原图,我们认为 这种人类应属于 平脸人的一个支系。 真人属要到距今 230万年之前才会诞生。而所谓的“Homo naledi”生活于约 300万年前,不应该是真人属的一个分支。

220万年以前倭黑猩猩和黑猩猩还是共祖没有分化出来。版主有没有尼安德特人和现代人类共祖的五十万年前平脸人的线粒体进化分支图。
