Primates: The oldest lived about 70 million years ago. These small mammals inhabited the forest trees and fed on eyes and insects.
Hominoids: They are primates that lived approximately 22 to 14 million years ago. O proconsul, which was the size of a small gorilla, lived in trees, but also descended to the ground; it was quadrupedal, that is, it moved on all fours. Descendant of the proconsul, the kenyapiteco sometimes he straightened and moved on his hind legs.
Hominids: Family that includes the australopithecine gender and also the human race. O Afanese australopithecus, which lived about 3 million years ago, was a little taller than the chimpanzee. He was already walking on both feet and had long arms hanging from the trees. Taller and heavier, the african australian lived between 3 million and 1 million years. He walked upright and used his hands to gather fruit and throw stones to slaughter animals.
Homo habilis: First hominid of the genus Homo. It lived around 2.2 million to 780,000 years ago. He made simple stone instruments, built huts, and probably developed a rudimentary language. Its traces were only found in Africa.
Homo erectus: Descended from Homo habilis, lived between 1.8 million years and 300 thousand years ago. It left Africa, reaching Europe, Asia and Oceania. He made more complex stone instruments and covered his body with animal skins. He lived in groups of twenty to thirty members and used more sophisticated language. It was the discoverer of fire.
Neanderthal Man: Probably a descendant of Homo erectus, it lived about 200,000 to 30,000 years ago. Skilled, he created many tools and made weapons and shelters with animal bones. He buried the dead in the caves with flowers and objects. He lived with the first modern men and disappeared for reasons unknown to this day.
Homo sapiens: Descended from Homo erectus, it appeared between 100,000 and 50,000 years ago. It is the modern man. It spread throughout the earth, leaving various instruments of stone, bone and ivory. He developed painting and sculpture.
Keep in mind, however, that this listing is not complete. It only summarizes what was possible to conclude from the fossils studied until today.
There are still many pieces left in the puzzle of human evolution, for example, the much sought after "missing link," that primate and human-like specimen that would explain an important step for humanity in its fascinating adventure on Earth.
