Early hominin auditory capacities.
Studies of sensory capacities in past life forms have offered new insights into their adaptations and lifeways. Audition is particularly amenable to study in fossils because it is strongly related to physical properties that can be approached through their skeletal structures. We have studied the anatomy of the outer and middle ear in the early hominin taxa Australopithecus africanus and Parant...
متن کاملEarly hominin auditory ossicles from South Africa.
The middle ear ossicles are only rarely preserved in fossil hominins. Here, we report the discovery of a complete ossicular chain (malleus, incus, and stapes) of Paranthropus robustus as well as additional ear ossicles from Australopithecus africanus. The malleus in both early hominin taxa is clearly human-like in the proportions of the manubrium and corpus, whereas the incus and stapes resembl...
متن کاملEarly hominin biogeography in Island Southeast Asia.
Island Southeast Asia covers Eurasia's tropical expanse of continental shelf and active subduction zones. Cutting between island landmasses, Wallace's Line separates Sunda and the Eastern Island Arc (the Arc) into distinct tectonic and faunal provinces. West of the line, on Sunda, Java Island yields many fossils of Homo erectus. East of the line, on the Arc, Flores Island provides one skeleton ...

متن کاملEvolution of the Early Hominin Hand
The hand is among the most primitive anatomical regions in the human body. The basic fi ve-digit pattern of our manus, including the number of bones in each ray and the retention of many extrinsic and intrinsic muscles (see Chap. 7 ), is likely retained from the ancestral condition for all mammals. While primate hands are generally characterized by two major novelties, namely, nails instead of ...
