Overview: Au. History of Discovery: The Taung child, found in , was the first to establish that early fossil humans occurred in Africa. How They Survived: The hunter or the hunted? How do we know what they ate? Evolutionary Tree Information: Many scientists consider either this species or Au. Where did it come from? Was it a descendent of Au.
Is Au. In , scientist Ron Clarke found four left early human foot bones while searching through boxes of fossils at Sterkfontein, a site in South Africa where most Au. He dubbed this fossil "Little Foot", and has since found that it comes from a 3. When this fossil is completely excavated, it will shed light on several questions about this species if it is designated as an Au.
What did its post-cranial skeleton look like? How does it compare to STS 14 , another partial skeleton of Au. References: First paper: Dart, R. Other recommended readings: Berger, L. Taung Child This 3-year-old child's skull is the first early human skull ever discovered in Africa. Chickens, chimpanzees, and you - what do they have in common?
Grandparents are unique to humans How strong are we? Whilst its possible that there are older specimens we have yet to find, this also raises the intriguing possibility that stone tools were first manufactured by an earlier species. Further, since Homo habilis is the oldest member of Homo this means that stone tools may have been manufactured by the Australopithecines.
Despite this connection to later stone tool capable species nobody really believed that Australopithecus was capable of creating such technology. This is because they are markedly similar to apes in many aspects, with long arms, long curved fingers, short legs, small brains and they spent a lot of time in the trees to name but a few similarities.
Given that no modern ape is capable of manufacturing tools as sophisticated as even the earliest, most primitive Oldowan it was believed the ape-like Australopiths could not either. Modern primates do use stones to extract resources from their environment, but these exploit rocks as they occur naturally.
Although this behaviour is quite sophisticated — the Capuchins have learnt to dry nuts out in the sun first to soften them up — they carry out no alteration to these raw materials like Oldowan cores , nor produce new tools from them like Oldowan flakes.
Whilst chimps in captivity can be trained to carry out these tasks the results are still markedly different from Oldowan technology being much smaller and less refined. This difference stems from the fact that chimpanzees are quadrupeds and thus have to sacrifice some dexterity in their hands for weight bearing adaptatio ns.
Since Australopithecus was never a quadruped then they likely lacked these limitations, so tool use amongst that genus is not as implausible as once thought. These wider fingertips increase the stability of small items you hold in a precision, pincer grip such as stone tools. The chronological relationship of hominin taxa.
Distance between them roughly correlates to anatomical similarity. However, this anatomical evidence is merely circumstantial. Are there any more definitive associations between Australopiths and stone tools?
Australopithecus garhi is one of the last Australopiths, appearing just before the emergence of Homo habilis. This close temporal association has led some to suggest that it is the ancestor of our genus, although the lack of distinct Homo -like traits make this far from certain.
Nonetheless it seems to be closely related to Homo somehow although most likely as an extinct sister lineage. Australopithecus garhi was found at Bouri, Ethiopia, a mere 96 km from Hadar were the earliest Oldowan tools were found. Oldowan tools were also found at Bouri but they were located on the surface of the site. Not being associated with any sediments they could not be dated, thus we do not know whether they are contemporary with Au. Some of the bones with tool marks from Bouri.
These bones had cut marks on them which, when analysed under a microscope, are consistent with stone tools. There were also percussion scars, consistent with the bones being hit with hammer stones. A femur from a horse species was found nearby that also had similar stone tool damage, consistent with hominins dismembering and filleting the leg. As such these bones provide conclusive evidence of hominins at Bouri using stone tools 2. And the only hominins we know of living at Bouri at this time is Australopithecus garhi.
Evolutionary anthropologists may find an older Homo habilis tomorrow, or even older examples of the Oldowan may be found that associate it with an early Australopith; we simply cannot know. However this association provides significant evidence of Australopithecus making stone tools and so I have no problem saying that Australopiths most likely made the first stone tools.
