According to anthropology, Australopithecus Afarensis did have opposable thumbs. This construct, it is thought, gave it the ability to form tools and hunt for food more efficiently.
Australopithecus afarensis is unique for their combination of both ape-like and human-like features, such as a small brain size, human-like teeth, and ape-like arms and legs. They were bipedal, meaning they could walk on two feet, which was a key step in human evolution. Lucy, a famous Australopithecus afarensis fossil, provided valuable evidence of their bipedal locomotion.
Fossils of the knee joint and pelvis of Australopithecus anamensis and Australopithecus afarensis show adaptations for bipedal locomotion, such as a valgus knee angle and a broader, shorter pelvis. Also, the position of the foramen magnum at the base of the skull suggests an upright posture. Lastly, footprints in volcanic ash at Laetoli in Tanzania show bipedal walking by Australopithecus afarensis.
The fossilized remains of Australopithecus afarensis were given the nickname "Lucy," after the Beatles song "Lucy in the Sky with Diamonds."
The exact reasons for the extinction of Australopithecus afarensis are unknown, but possible factors could include changes in climate, competition from other species, or inability to adapt to environmental changes.
Siamangs have an opposable thumb on their hands, which allows them to grasp objects firmly, similar to humans. They also have an opposable big toe on their feet, which enhances their ability to grip branches and move through the trees with agility.
Australopithecus afarensis was created in 1978.

Australopithecus afarensis is one of the earliest known bipedal species, but it is not definitively the first one. Other species before Australopithecus afarensis also showed some bipedal characteristics. However, Australopithecus afarensis is a well-known example of an early hominin that exhibited consistent bipedalism.

Archaeologists have no way of determining whether the Australopithecus afarensis had leaders or not. The only thing they can say for certain is that it was a partially quadrupedal species that had hominid features.
By Caleb Australopithecus Afaerensis. I do not think that this species of early humans had shelters.
The dental formula for Australopithecus afarensis is 2.1.3.3. Their dental formula indicates the number and arrangement of different types of teeth in one half of the mouth.
