They also had small canine teeth like all other early humans, and a body that stood on two legs and regularly walked upright. Their adaptations for living both in the trees and on the ground helped them survive for almost a million years as climate and environments changed.
How did Australopithecus defend themselves?
Australopithecus afarensis didn’t have tools, didn’t have big teeth and was three feet tall. He was using his brain, his agility and his social skills to get away from these predators. “One of the main defenses against predators by animals without physical defenses is living in groups,” says Sussman.

Is the Australopithecus the first species to walk upright?
The Australopithecus anamensis tibia indicates bipedalism. It is the first species to walk upright! The cranial capacity of the Australopithecus anamensis is unknown. Male height is around 5 feet, while the females are around 4’3”.
Why was the Australopithecus still active in trees?
Many scientists believe Australopithecus afarensis was still active in trees because the fingers and toe bones of the species were curved and longer than the ones of the modern human. Also, its upper torso is stronger than ours and its arm and leg lengths are similar which also indicates the species was adapted to tree climbing.
How long did Australopithecus afarensis live on Earth?
According to the fossils recovered to date, Au. afarensis lived between 3.7 and three million years ago. This means the species survived for at least 700,000 years, more than twice as long as our own species, Homo sapiens, has been around. Where did Australopithecus afarensis live?
