The Australopithecus Afarensis

This type of primate lived 2.3 million years ago.

 It mainly fed on the food that was found in the trees of that time, until they came down from those trees (their old habitat) they came to live in the ground, so they had to evolve to adapt and thus be able to see more above the plants and thus be able to better see the environment to alert themselves to prey and similarly to nearby predators.

Australopithecus afarensis is an extinct hominid of the Hominin subtribe that lived between 3.9 and 3 million years. It was of slim and graceful build, and is believed to have inhabited only East Africa (Ethiopia, Tanzania, and Kenya). Most of the scientific community accepted that it may be one of the ancestors of the Homo genus.



Australopithecines had stout, long arms, similar to those of apes, indicating that they combined their movement on the lower extremities with the climbing of trees or climbing between branches.




They were small and thin, with a size of between 1.20 and 1.40 meters high. Sexual dimorphism in its species was quite pronounced, with the male being able to reach 50% more size than the female.
 

They probably lived in the oases of the African savannah, where there were still trees and more abundance of food, but not too much, otherwise the need to descend from the trees and learn to walk upright is not explained.


It is possible that the latter gave them the definitive advantage to be able to migrate, access other less populated food niches, or foresee predators in African grasslands, by being able to look up.
