The golden monkey of the monkey family is the most precious monkey of the monkey family. IUCN listed them as the research objects of Asian primates, and China government also listed them as national first-class protected animals, which is the "second national treasure" after giant pandas.
Yunnan golden monkey is one of the most hardy monkeys. Their habitat is in the coniferous forest belt above 3000 meters above sea level. The environment here is harsh, but they live extremely comfortably. He has a pink face, red lips are wide and thick, almond eyes are deeply embedded in the eye sockets, and his nose is slightly upturned.
Macaque is the monkey that has made the greatest contribution to human medicine. They are similar to humans in tissue structure, physiology and metabolic function. Some human diseases can only be discovered by experiments with macaques, and the corresponding treatment mechanism can be established. Because they have many similar biological and behavioral characteristics with humans. So she is the most common experimental monkey in human medicine and an ideal animal model to solve human diseases.
According to Xinhua News Agency, scientists in the United States and Tanzania recently reported that a monkey found in Tanzania last year belongs to a new genus of primates. This is the first time that scientists have identified a new genus among primates in more than 80 years.
This rare monkey was first discovered in Tanzania plateau in 2005. At that time, scientists initially judged that it belonged to the known genus Macaca based on a limited number of photos. However, not long after, one of the monkeys broke into the local farmland and died in a trap. Scientists examined its physical and genetic information for the first time and found that its DNA information is special and should be counted as a new genus. Scientists from research institutions such as the International Wildlife Conservation Society published a paper in the latest online edition of Science magazine, saying that since this monkey was first discovered in the mountainous area of Rowen, Tanzania, it should be counted as Rowen monkey.
The biological classification is in turn realm, phylum, class, order, family, genus and species. Scientists believe that the macaque found in Tanzania belongs to the animal kingdom, chordates, mammals, primates, monkeys and macaques. At present, there is only one species of Ardisia. Scientists estimate that there are only more than 500 Longwei monkeys in the world, all living in the mountainous areas of Tanzania.
The macaque is medium-sized and has a long tail. Except the abdomen and tail are white, the rest of the body is covered with taupe hair. Adult macaques have strange calls, similar to those of geese, and most of them live in the mountains at an altitude of about 2500 meters. Genetic information also shows that the closest "relative" to Rowen is Baboon. Although their living habits are very different, the former lives in the forest and the latter lives in the grassland, and their looks are also very different, but researchers believe that this is the result of adaptive evolution of animals. Scientists call for strengthening the protection of this rare animal, otherwise human beings may "lose it as soon as they find it".
In addition, add a Baidu netizen (100W) about knowledge introduction:
Monkey is a common name. Many animals in primates are called monkeys. Primates are 1 order mammals. The highest group in the animal kingdom, with developed brains; The track faces forward and the track spacing is narrow; The toes (fingers) of hands and feet are separated, and the thumb is flexible, and most of them can hold hands with other toes (fingers). Including prosimia and simian suborder. Protomonkey suborder has a fox-like face; No cheek pouch and buttock callus; The forelimb is shorter than the hind limb, and the thumb and big toe are developed, which can be opposite to other fingers (toes); The tail should not be curled or missing. Ape suborder has a human face; Most of them have cheek pouches and hip calluses; Most forelimbs are longer than hind limbs, and some big toes degenerate; Tails are long, some can be curled, and some have no tails. According to the geographical distribution or nostril structure, the suborder simian is divided into wide-nosed monkeys, also known as new world monkeys; Narrow-nosed monkeys, also known as old world monkeys. This order includes 1 1 family, about 5 1 genus, 180 species, mainly distributed in warm areas of Asia, Africa and America. Most of them live in forest areas. The largest primate is a gorilla, weighing 275 kilograms, and the smallest is a bonobo, weighing only 70 grams.
Primates' skulls are mostly large and spherical, which is caused by the shortening of jaws and the flattening of faces. The posterior orbital process develops to form a bony eye ring or a closed eye socket; Most species have short noses, and their sense of smell is not as good as sight, touch and hearing. Some lower species have highly developed olfactory centers in their brains, and they rely heavily on the sense of smell. Some lemurs have long noses. The nasal bones of snub-nosed monkeys and dolphin-tailed langurs degenerate, forming upturned nostrils. The nose of a proboscis bird is big and long. These special types are formed by the development of muscle or cartilage. The big toe of the foot can abut against the other toe, making the hands and feet become grasping organs. The five fingers of primitive monkeys can only be flexed and extended at the same time, and cannot be used alone. Palmar surface and □ surface are exposed, with finger and toe lines and different patterns. The foot pads are soft or wide, and all of them are flexible except the black apes. Most fingers and toes have flat nails. Generally speaking, there is little difference in the length of forelimbs and hind limbs, but the forelimbs of Red Tide Insects and Scarabaeidae are much longer than the hind limbs. Apes and humans have no tails. In species with tails, the tail length varies greatly, from only one protrusion to exceeding the body length. The tail of most species in the family Cephalaenidae has the function of grasping and is called the "fifth hand". Some old world monkeys (such as baboons) have brightly colored faces, buttocks or breasts, especially during the breeding season. The buttock has a hard lump composed of hard skin, which is called the buttock callus.
1 nipple in most species is located in the chest or armpit, while 1 nipple in monkeys is located in the abdomen. Male penises droop, most of which have penile bones, but tarsiers, marmosets, humans and some species do not. The testicles are wrapped in a bag. The female body has a double horn uterus or a single horn uterus. Body coat, some soft and thin, some thick and hard, or local long, or hair with different colors of links. Some hair on the top of the head is very long, forming a tufted crown, or short, flat-topped, or bald and hairless. Some people have long hair on their cheeks or chin, which is shaped like a beard. Some shoulders, backs and hips are covered with long hair. Some body hair is gorgeous.
Most primates live in different forms of arboreal or semi-arboreal life, and only ring-tailed lemurs, baboons and marmosets live in land or rock areas. Usually small groups, but also large groups. Most people can walk upright, but not for long. Most of them are active during the day, and at night they are refers to monkeys, some big lemurs and night monkeys. Japanese lemurs and Japanese lemurs are in dry and hot season in summer.
Sleep for a few days to weeks.
Most of them are omnivores, eating plant or animal food. There are different ways to choose food and feed. For example, monkeys are good at picking bugs in tree holes or crevices. Orangutans eat a lot and spend most of their time foraging. The stomach of colobus monkeys has a special structure, and most species eat plant food containing a lot of crude fiber.
Breeding 1 ~ 2 times a year, each fetus 1 offspring, and a few can have up to 3 offspring. Larvae grow slowly. Crawling on the mother's chest and abdomen or riding on her back during lactation, carried by her mother. Sexually mature females have menstruation, and males can mate at any time. Only lower monkeys, such as lemurs, sloths and lynxes, have a certain mating and breeding season.
The skull features of Dendrolimidae are very similar to those of some very primitive monkeys. Many anatomists and paleontologists have listed it as a primate, but its external morphology and ecological habits are very different from those of primates. Therefore, modern taxonomists have classified it as Dendrolimidae independently.
Primate fossils are found in Paleocene to Oligocene strata in North America and Europe, Miocene strata in Asia, Africa and Europe, and Pleistocene strata in South America, Africa and Madagascar. Primates have evolved for 60 million years. Early primate fossils found all over the world belong to primitive monkeys, of which more than 60 genera are now extinct. There are no primitive monkeys in America now, but there are a few species very similar to the primitive monkeys 50 million years ago on some islands in Africa and Asia, Madagascar and the Indian Ocean. The history of apes can be traced back to 30-50 million years ago. About 65,438+0,500-20 million years ago, the ancestors of apes had spread all over Europe, Asia and Africa, but today they only remain in tropical Asia and Africa.
