得益于新化石的不断发现,人们对于人类进化历史的认识日益深入。中上新世是古人类极度繁盛的一个时期,至今已命名的就有羚羊河南方古猿(Australopithecus bahrelghazali)、平脸肯尼亚人(Kenyanthropus platyops)和阿尔法南方古猿(A.afarensis)。进一步的分析令研究者们相信,当时应该存在更多的古人类。近期,研究者在埃塞俄比亚330万-350万年前的地层中又发现了一种新古人类,并将之命名为近 Thanks to the continuous discovery of new fossils, people’s understanding of the evolutionary history of human beings has deepened. The Mid-Pliocene is an extremely ancient period of mankind, has so far been named antelope Australopithecus Australopithecus bahrelghazali, Kenyanthropus platyops and Alpha Australopithecus (A.afarensis). Further analysis convinced the researchers that there should be more ancient humans at that time. Recently, researchers discovered another Neoprogan in the strata of Ethiopia 3.3 million to 3.5 million years ago, and named it near
