How many years ago do the Australopithecus live and where?
Found between 3.85 and 2.95 million years ago in Eastern Africa (Ethiopia, Kenya, Tanzania), this species survived for more than 900,000 years, which is over four times as long as our own species has been around.
In which time period did Australopithecus afarensis exist?
Australopithecus afarensis is an extinct species of australopithecine which lived from about 3.9–2.9 million years ago (mya) in the Pliocene of East Africa. The first fossils were discovered in the 1930s, but major fossil finds would not take place until the 1970s.
How old is the Australopithecus afarensis fossil?
3.5 to 3.3 million years old
The fossils date to 3.5 to 3.3 million years old and were discovered in Woranso-Mille in Ethiopia, close to sites of a similar age that produced A. afarensis specimens.
How long ago did Lucy the hominid live?
about 3.2 million years ago
The Lucy specimen is an early australopithecine and is dated to about 3.2 million years ago….Lucy (Australopithecus)

How tall was Australopithecus afarensis?
The body height of Australopithecus afarensis A.L. 288-1 (“Lucy”) has recently been estimated and calculated as between 1 m to 1.06 m; other estimates give ca. 1.20 m. In addition, it is often stated that her relative leg length was shorter than that of modern humans.
What year did Australopithecus live?
The various species of Australopithecus lived 4.4 million to 1.4 million years ago (mya), during the Pliocene and Pleistocene epochs (which lasted from 5.3 million to 11,700 years ago). The genus name, meaning “southern ape,” refers to the first fossils found, which were discovered in South Africa.
What era did Australopithecus live in?
How old was Lucy when she died Australopithecus?
Therefore, scientists have suggested that Lucy was between 12 and 18 years old when she died. Evidence from Lucy’s skeleton, specifically features of her left os coxa (hip bone) and her limb bones, also support the conclusion that she was a fully mature adult individual (Johanson, Taieb, et al.).
How old was Lucy Australopithecus when she died?
How tall was the Australopithecus afarensis when it lived?
This individual stood about 1.6 metres tall (30% larger than ‘Lucy’) and lived about 3.6 million years ago. These fossil footprints were discovered in Tanzania, East Africa and date to 3.6 million years ago. Fossil bones from A. afarensis have been found nearby so it is presumed that they left the tracks.
How did au.afarensis differ from modern humans?
Similar to chimpanzees, Au. afarensis children grew rapidly after birth and reached adulthood earlier than modern humans. This meant Au. afarensis had a shorter period of growing up than modern humans have today, leaving them less time for parental guidance and socialization during childhood.
Is the Australopithecus afarensis part of the genus Paranthropus?
It is also considered to be a direct ancestor of later species of Australopithecus and all species in the Paranthropus genus. The names Praeanthropus africanus and Praeanthropus afarensis have been suggested as alternatives by researchers who believe this species does not belong in the genus Australopithecus.
Is the Australopithecus a direct ancestor of humans?
Australopithecus afarensis is usually considered to be a direct ancestor of humans. It is also considered to be a direct ancestor of later species of Australopithecus and all species in the Paranthropus genus.
