Abstract: The long evolutionary way for human can be traced back to about 5 million years ago, in which two “missing links”,  Ardipithecus ramidus and Australopithecus sediba, have been validated. There are two conflicted hypotheses, “out of Africa” and multiregional origins. At present, the mixture of both hypotheses seems to be more valuable according to Neanderthal and Denisovan genome draft and other data. The ultimate explanation for being human is focused on the culturemaking brain, especially in the cerebral hemisphere asymmetry, that bolsters the framework for 4 graded languages and 3 types of world.

Key words: human, evolution, brain, culture, language
