Anthropoids include humans, Australopithecus, Homo sapiens, Homo erectus, etc. All species of human beings are commonly referred to as the superfamily of the suborder Primates. Distributed on all continents of the world, the early type is found only in the warm regions of Asia, Africa, and Europe.
Walking upright, arms not exceeding knees, degeneration of body hair, division of hands and feet, mandible.
Shallow and stout, degenerated canines and lower first premolars, enamel.
The wear of the thick, 3 molars varies greatly. <

Upright walking, arms not exceeding the knees, degeneration of body hair, division of hands and feet, shallow and stout mandibles, degeneration of canines and lower first premolars, thick enamel, and abrasion of the three molars vary widely. The brain is extremely developed, with language, labor, sociality, and class.

There are four genera and eight species of hominids, the genus of orangutans: Sumatran orangutans, Bornean orangutans.
Dabanuli orangutan. Gorilla genus.
Mountain gorillas, lowland gorillas. Chimpanzee genus: Chimpanzee, bonobos.
Homo: Homo sapiens. In the past, all kinds of orangutans were classified into the orangutan family, and humans were classified as a separate family.
Later, phylogenetic spectrum analysis of various orangutans and humans showed that the orangutan family is actually a paraphyletic group, not a rigorous biological classification, if humans are added, then all orangutans and humans form a monophyletic group, that is, all the descendants of a common ancestor. So the original orangutan family was merged with the hominidae family to form a new hominidae.

Humans belong to the mammals of the order Primate. The mammals of the primate feast include apes, lemurs and humans, and in addition to humans, they are mostly found in the warm regions of Oceania to build on the silver. In general, according to the degree of evolution, it can be divided into primitive protomonkeys, moderately advanced monkeys, and advanced apes and humans.
Humans are the most widespread species of terrestrial mammals, inhabiting every continent on Earth (although there are no permanent settlements in Antarctica). Humans are able to reproduce throughout the year. Dioecious, in vivo fertilization, viviparous, gestation period is 4 weeks on average.
There is usually a single offspring produced, and although twins are occasional, multiple births are rare. Birth intervals, birth weight, weaning time, independence, and sexual maturity all vary greatly with the nutritional status of mothers and young people, and are influenced by cultural practices.
Humans are opportunistic omnivores that show remarkable ingenuity in extracting, producing, processing, and preserving food. is the only species that can be controlled or **, and all known extant populations of Homo sapiens are cooking. Regional differences in diet are influenced by availability in specific contexts, cultural traditions such as food preferences and avoidance, and genetic factors.

"Man" is an animal of the primate family Homo genus. It is a primate belonging to the same family as chimpanzees, gorillas, orangutans, gibbons, and hinged apes.
Homogeneidae, refers to apes. There are some other species of Homo members in prehistory, which can generally be divided into two subfamilies, namely the early Australopithecus subfamily and the later Homo subfamily.
Homo sapiens (scientific name: homo) is a genus under the subfamily Homo, a total of 14 species, of which 13 species have become extinct, and only one remains, namely homo sapiens, with more advanced morphological characteristics than Homo erectus.

Humans belong to the animal kingdom, the phylum Minsofa, the subphylum vertebrates, the class of mammals, the order primates, the suborder of simonoids (suborder apes), the general family of apes, the family Homo, the genus Homo, the species of Homo.
Human Profile:
Homo sapiens (scientific name: Homo sapiens) is the only living species of the genus Homo sapiens. The morphological characteristics are more advanced than those of Homo erectus. It is divided into early Homo sapiens and late Homo sapiens.
Early Homo sapiens used to be called homin, lived 250,000 40,000 years ago, and was mainly characterized by a large brain volume, more than 1,300 ml; The brow crest is well developed, the forehead is sloping, the occipital region is prominent, the nose is wide and flattened, and the jaw is protruding. It is generally believed that Homo erectus evolved from Homo erectus, but it is disputed that Homo erectus became extinct after the rise of Homo sapiens (modern humans) from blinding Africa, or before that.
Late Homo sapiens (new humans) are anatomically modern humans. It began to appear about 450,000 years ago. The main morphological differences between the two are the reduction of the anterior teeth and face, the weakening of the brow ridge, and the increase in skull height, which is more pronounced in modern humans.
Late Homo sapiens arms were no more than knees, body hair was degenerated, there was language and labor, and there was a social and class character.
With more than 500 species, the muridae is the second largest family of mammals, and its members are very diverse and can be divided into several subfamilies, most of which belong to the murine subfamily murinae. The black mus rat rattus, the brown rat rattus norvegicus and the mus musculus of the mouse genus have arrived all over the world with humans and are the most successful and common mammals, generally regarded as pests, and albino varieties have also been cultivated for medical experiments. In addition to human-dispersed species, the natural distribution of rodents is confined to the Old World, with many species being limited and some endangered or extinct. >>>More
