Australopithecus Afarensis

Afarensis A. afarensis is the most famous Southern ape, the number of samples for this kind. Based on speculation of their immediate family, gorillas and chimpanzees, we can infer the possible social structure of A. afarensis. This species was named by Johanson and Taieb in 1973. The discovery of this skeleton caused intense debate about the effectiveness of the species. Seeds are eventually accepted by most researchers as a new species of A. amurensis and may be candidates for human ancestry.

The famous fossil of "aucalyche" Lucy "belongs to this species. They are said to live in the continent of Africa. And they are shorter than Australopithecus ramidus and have small skulls without flat nose and chin. They can walk with two legs, but their feet are slightly bent, so walk like a squat. Curved legs, fingers and toes allow them to climb trees and live there. Their teeth and jaws are big. Hom habilis - His face is like his ancestor. The size of the skull and brain shows that he can talk. The earliest tools came from this age. Homo habilis is known as "hands-on" because it is the person who first created and used the tool. He is about 5 feet tall and standing upright

Our ancient ancestor Lucy, an ancient Aachen famous fossil, lives 3 million to 4 million years ago and has a body between contemporary humans and animals. The southern pelvis and leg bones are similar to ours, and the Afghan gyros may be upright like us. But they are very different in very important respects: their brains are relatively small - nearly a third of today's Homo sapiens. "If you want to know the mechanism of a car, reading designer notes saves a lot of resources," says Forero, the lead author of natural research. "If you want to understand how the brain works, you can save a lot of resources by understanding your brain design." In the case of the brain, this is to understand the power of natural selection It means.

Eventually the South African species evolved at last and two new strains were born. The genus Paranthropus, which appeared 3 million years ago, is morphologically different from the southern ape and has very specialized properties based on its regionally restricted diet. As an incredibly strong man, the members of this group represent a unique development of the entire human family. Among them, Paranthropus aethiopicus lives in a mixed area of ​​savanna and forest areas, and monkeys will live over time. This animal shows a somewhat primitive feature and shares many features with the astroprophex aphlenesis. This kind of face is similar to prediction, and their brains are close to 400 cubic centimeters. Aethiopicus also has large sagittal and cheekbone arches for heavy chewing
