But the focus of the current debate is that "modern man, that is, late Homo sapiens, is a new species different from Homo erectus and early Homo sapiens, which originated in Africa between 200,000 and 654.38 million+years." This theory holds that Africa is the only origin of modern people, that is, late Homo sapiens. It went out of Africa 60,000 to 70,000 years ago and gradually replaced the primitive ancients in East Asia and other regions, including "Beijingers".
Early Homo sapiens used to be called the ancients, living 250,000 ~ 40,000 years ago. Its main feature is large brain capacity, 1, more than 300 ml. The brow ridge is developed, the forehead is inclined, the occipital bone is prominent, the nose is wide and flat, and the jaw is prominent. It is generally believed that it evolved from Homo erectus. Late Homo sapiens used to be called a new human, and he was a modern man in anatomical structure.
It began to appear about 40 thousand to 50 thousand years ago. The main morphological differences between them are that the front teeth and face shape are reduced, the brow ridge is weakened and the skull height is increased, which is more obvious to modern people. In the late stage of Homo sapiens, race formation. Walking upright, arms below the knee, body hair degeneration, division of labor between hands and feet, shallow and thick mandible, extremely developed brain, language and labor, sociality and class nature.
