非洲,由于最早发现早期人类化石,从2千万年前的埃及古猿到非洲最早的直立人,前后相继,没有缺环,形成一个发展序列,所以从60年代起人们就公认人类起源在非洲。然而到了80年代,人类学家又在金沙江边的攀西古裂谷发现了1900万年前的江苏古猿化石,此后又相继发现了1 400万年前的开远古猿、800万年前的禄丰古猿、400万年前的元谋人猿超种以及距今400万至350万年的蝴蝶猿人化石。后来又挖掘出距今250万年的东方直立人 In Africa, since the earliest human fossils were discovered, from the Egyptian apes about 20 million years ago to the earliest erectus in Africa, one after another, without lacking a ring and forming a sequence of development, since the 1960s people have recognized human origins in Africa .
