As for the origin of human beings, it was not until the 19th century that they embarked on the path of science. Darwin's theory of evolution is one of the three major scientific discoveries in the 19th century. However, scientific exploration has not stopped. With the development of human archaeology, many ancient human fossils have been found and many painstaking theories about the origin of human beings have emerged. For example, paleoanthropologists believe that the evolution from ape to man can be divided into four stages: Australopithecus, Homo habilis, Homo erectus and Homo sapiens. There are obvious differences in physical characteristics and cultural relics among the four kinds of ancient human fossils in different periods, which fully reflect the four stages of human evolution. What's more: the sea ape theory, the sea land double ancestor compound theory, the alien theory and so on. These theories all discuss the origin of human beings from different angles.
无论是“海猿说”“海陆双祖复合说”还是“外星人说”,都在有力地向传统的“从猿到人”的进化论学说发出挑战,但要形成公认的科学结论,还证据不足。科学在发展,研究在深入,人类将用自己的智慧,来解开自身的谜团。
No matter the "sea ape theory", "sea land double ancestor compound theory" or "alien theory", they are all effectively challenging the traditional evolutionism theory of "from ape to man", but there is insufficient evidence to form a generally accepted scientific conclusion. Science is developing and research is deepening. Human beings will use their own wisdom to solve their own mysteries.
