Differences Between Australopithecus Afarensis and Homo Sapiens Sapiens (modern) The Australopithecus Afarensis was dated back 3.9-3 mya. The characteristics were still far from human. It had an apelike face, with a low forehead, and a bony ridge over the eyes. It had a flat nose, and barely had a chin. The Australopithecus Afarensis had a protruding jaw with large back teeth. The cranial capacity varied from about 375cc to 550 cc. It's skull was similar to a chimpanzee, except it's human like teeth. The pelvis and legs closely resembled those of a modern man. The females were smaller than males, and their average height was from 107cm, to 152cm. Their hands curved, but similar to humans. The Australopithecus Afarensis was first located in Ethiopia, in 1974.

The modern Homo Sapiens Sapiens date back 120, 000 years ago and to this present day. The brain size is about 1350cc, which is smaller than the Australopithecus Afarensis. The forehead rises sharply, and the eyebrow ridges are very small, and usually absent. The chin is prominent, and the skeleton is very gracile. The face, jaw and teeth are more robust. Modern Homo Sapiens started to use a variety of tools, materials, and wore clothing. Musical instruments, art, religions and cave paintings were developed at the beginning of this era. To this day, new and more modern technologies are being developed. The first discovery of the earliest Modern Homo Sapiens date back in 1868, found in Africa.
