科学史有时会跟科学家开玩笑,因为科学假说被新的论证否定后,有时会出现理论危机。1912年有两个西方学者,摩尔根(J.Morga n)和劳弗尔(B.Laufex)坚持说中国无史前时代,但是1920年发现甘肃庆阳旧石器;1921年发现仰韶遗址;1922年发现辽宁沙锅屯遗址;1928年发现龙山遗址。继1927年发现北京人臼齿之后,1929年发现北京人头骨。不上二十年,把权威人士如摩尔根等的谬说否定了。中国的史前文化尽管得到承认,但它是从什么地方来的呢?这一来又见仁见智了。虽然 The history of science sometimes jokes with scientists because, after the scientific hypothesis is denied by new arguments, there is sometimes a theoretical crisis. In 1912 two Western scholars, J. Morgan and B. Laufex, insisted that China had no prehistoric age, but that the paleolith was discovered in Gansu in 1920; the Yangshao site was discovered in 1921; the 1922 Found Liaoning Shapotun site; found in 1928 Yongsan site. Following the discovery of Peking molar in 1927, the Beijing human skull was discovered in 1929. Within twenty years, the fallacies of authoritarians such as Morgan have been negated. Despite its recognition, China’s prehistoric culture came from a different perspective. although
