australopithecus garhi
Stone tools were not found at this site, but at the nearby, contemporaneous site Gona. The species name, garhi, means ‘surprise’ in the Afar language. If the antelope bones found at the site were butchered by this species, then they must have included significant amounts of meat and marrow in their diet.
The first identifiable Australopithecus fossils–an adult ulna (BOU-VP-11/1)–were found on 17 November 1996 by T. Assebework. The associated fragmentary skeleton indicates a longer femur (compared to other Australopithecus specimens, like ‘Lucy’) even though long, powerful arms were maintained. Relatively, the postcanine teeth, the molars and premolars, are massive (post-canine megadontia), similar to or greater than those of other australopithecines and of the large-toothed Paranthropus robustus. Reconstructing the physical environment in which our ancestors lived allows us to gain a greater understanding of their day-to-day lives. A. garhi possibly produced the Oldowan industry which was previously considered to have been invented by the later H. habilis, though this may have instead been produced by contemporary Homo. Although similar to other australopithecines, it displayed some surprising features. This is a primitive feature. [5], Like other australopithecines, A. garhi had a brain volume of about 450 cc (27 cu in), a sagittal crest running along the midline of the skull, and a prognathic jaw (the jaw jutted out).
This could mean that A. garhi, compared to other Australopithecus, either had a slower overall growth rate, or a more rapid leg growth rate. The fossils are significant as they help fill the period between 2 and 3 million years ago; a time with a poor human fossil record. ‘Environment and behavior of 2.5-million-year-old Bouri hominids’. The genus or group name Australopithecus is derived from the Latin word ‘australo’ meaning ‘southern’ and the Greek word ‘pithecus’ meaning ‘ape’.
This opinion changed when new evidence showed this species had many features intermediate between apes and humans. There are some interesting connections between the four major trends. It most likely ate plant material and possibly some meat. [7], Mammalian bones associated with the A. garhi remains exhibit cut and percussion marks made from stone tools: the left mandible of an alcelaphine bovid with three successive, unambiguous cut marks presumably made while removing the tongue; a bovid tibia with cut marks, chop marks, and impact scars from a hammerstone, possibly inflicted to harvest the bone marrow; and a Hipparion (a horse) femur with cut marks consistent with dismemberment and filleting. Paleoanthropologists are constantly in the field, excavating new areas with groundbreaking technology, and continually filling in some of the gaps about our understanding of human evolution.
