Thereafter, due to a large number of ancient human fossils found in the material, some people think that the human and ape in the new Middle and Late Miocene Tertiary (180-600 million years ago) started to divide the community a few years Dryopithecus health of various species are the ancestors of monkeys, a species which evolved into the first person Branch representatives - Ramapithecus later evolved from the Ramapithecus dating back 200 million years ago, Australopithecus, and then through the Homo erectus, early Homo sapiens, late Homo sapiens (M. Krume farmer) and evolved into modern man.
此后，由于大量古人类化石材料的发现，部分人认为人和猿是在新第三纪的中新世中晚期（距今180—600万年间）开始分化的，森林古猿里的几个种是各种现生猿的祖先，其中有一个种进化成最早的人科代表——腊玛古猿，以后由腊玛古猿进化成距今200万年前的南方古猿，再经过直立人、早期智人、晚期智人而进化成现代人。
Some scholars, according to Kenyan fossils found in Ramapithecus the canine fossa be able to contribute a fixed exercise the muscles of the lips when they talk, suggesting it may have the ability to speak after mid-century, some scholars.20 After a Ramapithecus differences between the age of fossils and ape research, raise objections that Ramapithecus not human ancestors, but the ancestors of apes and advocated dividing line between ape was 500 years ago.
有的学者据肯尼亚发现的腊玛古猿化石的犬齿窝能固定一块有助于说话时嘴唇运动的肌肉，推测其可能具有说话能力。20世纪中叶后一些学者经过对腊玛古猿化石和人猿分野年代的研究，提出异议，认为腊玛古猿不是人类的祖先，而是猩猩的祖先，主张人猿分野是在500万年前。
