Australopithecus afarensis

Australopithecus afarensis is an early human species have paleoanthropologists longest running and most famous discovered remains of more than 300 people! Today it was between 3.85 and 2.95 million years in East Africa (Ethiopia, Kenya, Tanzania), this species survived for more than 900,000 years, which is more than four times longer than our species has existed. There are sites of Hadar, Ethiopia better known (‘Lucy’, AL 288-1 and the “first family”, AL 333); Dikika, Ethiopia (Dikika skeleton “child”); and Laetoli (fossils of this species along the paths of the oldest biped footprint documented).

As in chimpanzees, Au. afarensis children grew rapidly after birth and reached adulthood earlier than modern humans. This meant Au. afarensis had a shorter period of growth that today’s modern man, leaving them less time for parental guidance and socialization in childhood.

Australopithecus afarensis

Au. afarensis had both monkey and human traits: the members of this species had faced apelike proportions (flat nose, projecting lower jaw hard) and brain (with a little brain, usually less than 500 cubic centimeters – about a third the size of a modern human brains), and a long and strong arms with curved fingers adapted to climbing trees. They also had small canines of a body, which stood on two legs and teeth regularly walked upright, like other early humans, and. Their adaptations for living in trees and soil helped them survive for nearly a million years as climate change and the environment.
