2024年11月13日 · A recent study has challenged previous assumptions about early human tool use by examining the hand structure of ancient hominins, specifically the Australopithecus genus. Model of a female Australopithecus afarensis at Natural History Museum, Vienna.

2010年8月11日 · Two fossilized bones with cut marks and percussion marks were unearthed in Ethiopia. The bones are about 3.4 million years old and provide the first evidence that Australopithecus afarensis used...

2024年1月3日 · Fossils of Australopithecus garhi are associated with some of the oldest known stone tools, along with animal bones that were cut and broken open with stone tools. It is possible, then, that this species was among the first to make the transition to stone toolmaking and to eating meat and bone marrow from large animals.

A. garhi was associated with large mammal bones bearing evidence of processing by stone tools, which may indicate australopithecine tool production. [ 63 ] [ 64 ] [ 65 ] [ 66 ] Stone tools dating to roughly the same time as A. garhi (about 2.6 mya) were later discovered at the nearby Gona and Ledi-Geraru sites, but the appearance of Homo at ...

Australopithecus is the given group or genus name. It stems from the Latin word Australo, meaning “southern,” and the Greek word pithecus, meaning “ape.” Within this section, we will outline these differing species’ geological and temporal distributions across Africa, unique derived and/or shared traits, and importance in the fossil record.

2024年11月13日 · A recent study 1 into the hand bones of Australopithecus afarensis — the species that includes the famous "Lucy" — suggests that early hominins may have been adept at using tools more than 3 million years ago. Researchers from the University of Tübingen have found that australopithecine hands exhibited the necessary muscle attachments for ...

2015年1月23日 · A team of scientists led by Dr Tracy Kivell of the University of Kent and University College London has found strong evidence for stone tool use among Australopithecus africanus (3 to 2 million years ago) and several Pleistocene hominins, traditionally considered not to have engaged in habitual tool manufacture.

2017年8月1日 · Was Australopithecus afarensis able to make the Lomekwian stone tools? Towards a realistic biomechanical simulation of hand force capability in fossil hominins and new insights on the role of the fifth digit Australopithecus afarensis était-il capable de fabriquer les outils du Lomekwien ?

2010年8月12日 · The bones date to roughly 3.4 million years ago and provide the first evidence that Lucy’s species, Australopithecus afarensis, used stone tools and consumed meat. The research is reported in the August 12th issue of the journal Nature. The two bones found in Dikika, Ethiopia, clearly show traces of cuts and blows.

The skeletal remains were found associated with antelope bones bearing cut marks, apparently from stone tools. Stone tools were not found at this site, but at the nearby, contemporaneous site Gona. These are the earliest dated stone tools that have been found, but may have been left by another species.
