females grew to only a little over one metre in height (105 – 110 centimetres) and males were much larger at about 150 centimetres in height, rib cage was cone-shaped like those of apes, brain was small, averaging approximately 430 cubic centimetres and comprised about 1.3% of their body weight, reorganisation of the brain may have begun with some enlargement to parts of the cerebral cortex. This species may be a direct descendant of Au. Au. These Lomekwian tools were made from volcanic rock and crafted into cores, flakes and potential anvils. The unfortunate stereotype of these people as dim-witted and brutish cavemen still lingers in popular ideology but research has revealed a more nuanced picture. It was found in 1924, but it took over 20 years after that before scientists accepted the importance of Africa as a major source of human evolution. Her small skull, long arms and conical rib cage are like an ape's, but she has a more human-like spine, pelvis and knee due to walking upright. We don’t know everything about our early ancestors—but we keep learning more! This early human's spine had the same curve. This fossil is the type specimen’or official representative of this species. In 2010, fossil bones bearing cut marks were found in Dikika in Ethiopia, dating to about 3.4 million years old. afarensis may have foraged in the tree canopy as well as on the ground, and probably retreated to the trees at night to avoid predators and for a good night's sleep. They were attributed to Au. If correct, A. afarensis was not the only hominin around in east Africa at this time. This is the genus or group name and several closely related species now share this name. Image credit: gadigal yilimung (shield) made by Uncle Charles Chicka Madden. These were made by two individuals, one of whom was much taller and heavier, walking in the same direction as the original group. A new species of the genus Australopithecus (Primates: Hominidae) from the Pliocene of Eastern Africa. The one on the left was much smaller than the other and may have been a child. As mentioned, it is categorized as a gracile form of australopith. jaws and teeth were intermediate between those of humans and apes: jaws were relatively long and narrow. Want to know how we know how old Taung Child is and how the child died? The skeleton’s name was inspired from The Beatles’ song with the title “Lucy in the Sky with Diamonds”.

En 1978, Donald Johanson, Tim White et Yves Coppens définissent l'espèce Australopithecus afarensis. | Photo by Jim Linwood, used with permission. This is a broad range, pointing to high sexual dimorphism - the difference in size and shape between males and females. If they withstand scrutiny, this would be the earliest evidence of meat-eating behaviour by a hominin. africanus was anatomically similar to Au. anamensis and Kenyanthropus platyops - probably gave rise to two more recent hominin groups, Homo and Paranthropus, before 2.5 million years ago. ‘Lucy’ AL 288-1 – a partial skeleton discovered in 1974 by Donald Johanson in Hadar, Ethiopia. afarensis ate from looking at the remains of their teeth.

It is best known from the sites of Hadar, Ethiopia (‘Lucy’, AL 288-1 and the 'First Family', AL 333); Dikika, Ethiopia (Dikika ‘child’ skeleton); and Laetoli (fossils of this species plus the oldest documented bipedal footprint trails).
