人类起源之谜是科学史上的六大悬案之一。早在19世纪,第一个提出人类起源问题的英国博物学家赫胥黎,根据达尔文的进化论发现人类的进化过程有缺环,即人类不可能直接从猿进化而来。之后日本科学家则明确指出:在猿与人之间应有一种“类猿人”。但这一理论一直未得到证实,原因是从未发现过类猿 The mystery of human origin is one of the six unsolved cases in the history of science. As early as the 19th century, the first British naturalist who proposed the issue of human origin, Huxley, discovered that there was a gap in the evolutionary process of human beings based on Darwin’s theory of evolution, that is, humans could not have evolved directly from the skeleton. Later, Japanese scientists clearly pointed out that there should be a kind of “kind of people” between the people. However, this theory has not been confirmed because the class has never been found.
