Recently, I looked up a lot of information about primates and bought zoological research on Taobao specifically for this problem. Personally, I think I have learned and mastered this knowledge in detail. Although I'm not a science major and my major is not life science and technology, it may be a personal hobby, and I'm allergic to primates and anthropology recently. Hehe ~)
Xu Hankui, an archaeologist in Nanjing, claimed that the ancestors of human beings were primates (which Baidu found unintentionally when searching). Zoology The earliest human beings appeared in the late Oligocene to the early Miocene, and they were also the earliest primates to walk upright. After a long time, those Australopithecus that adapted to environmental changes gradually evolved into Homo erectus (the most unique species excavated in modern archaeology).
The status of modern people in the animal kingdom is primate, hominid, subfamily and Homo sapiens.
Brain science is brain science. You can find some primate courseware. Including Apeoidea and Human Brain. The existing members of the Human Brain Family include Silver Apes, Gorillaceae and Human Brain Family.
Anthropocene is a unit between Anthropocene and Anthropocene. According to modern taxonomy, Humaninae belongs to Humanoidea, Humanoidea and Catasuborder. In the early days, the definition of hominid (that is, the symbol that distinguishes it from other humanoid superfamily species) was mainly about whether tools could be made, and it was believed that making tools was a unique ability of human beings. Mao * * in his "He Xinlang. Reading history ",there is a saying that" apes are different. Only a few stones have been ground. This word was written in 1964, but this view was challenged at this time. In 1960s, jane goodall, a young woman who graduated from a high school in Britain, went deep into the African jungle to observe the life behavior of chimpanzees. She found that chimpanzees like to eat ants, but ants are hidden in ant graves and are not easy to get, so chimpanzees will break the branches of grass and turn them into a straw stick, and use this straw stick to catch ants to eat. Jane Goodall thinks that chimpanzees can process grass sticks in this way, which means that animals can also make tools. Her discovery was recognized by anthropologists. Since the ability to make tools is not unique to human beings, nature cannot be used as a boundary sign between the oldest human beings and their ancestors-apes.
Hominidae are now generally divided into two subfamilies (Australopithecus and Hominidae) and three unidentified genera. But Australopithecus generally includes two genera, namely Australopithecus and Paranthropus. It is worth mentioning that the genus Paranthropus was cancelled and later restored. Three species of this genus are now recognized as Australopithecus. I guess the reason for restoring this genus is to show that members of this genus can be sure that they have no inheritance relationship with modern people. Hominini now includes a definite genus -Homo and a controversial genus -Kenyanthropus. The other three unidentified genera of Anthropoceae are Ardisia, Aurelian and Sahelanthropus. The existence time of members of these three genera is close to the time predicted by molecular biology that human ancestors and chimpanzee ancestors separated (5-7 million years ago). Whether these three genera are closer to humans or chimpanzees is still inconclusive. On the other hand, it can be said that there is no conclusion because they are transitional, and transitional types often show the characteristics of both.
However, this brings a new problem. If one of these three genera is proved to be the same ancestor of humans and chimpanzees, then chimpanzees should be divided from the cappella family and belong to the Anthropoceae family according to taxonomic principles (in fact, some people do claim this now), but chimpanzees obviously do not meet the definition of Anthropoceae. There is still a heated debate in the scientific community.
Finally, although humans and other non-human primates belong to the same primate, they belong to different families, namely, Anthropoceae and Scarabaeidae. They belong to different families, or they belong to different families. Therefore, there is reproductive isolation between the two species. Humans and orangutans can't have offspring.
