Are humans also mammals, are humans mammals

Humans are mammals. Humans belong to the primate order of mammals, and primate mammals include apes, lemurs, and humans, among others.

In addition to humans, it is mostly found in warm regions outside Oceania. In general, according to the degree of evolution, it can be divided into primitive protomonkeys, moderately advanced monkeys, and advanced apes and humans.

People know how to use languages, have a variety of complex mutualistic social organizations, and like to develop complex technologies. These behavioral differences also give rise to different beliefs, legends, rituals, values, and social norms in different cultures. In cultural anthropology, human beings are defined as those who are able to use language, have complex social organizations and technological developments, and above all are able to establish groups and institutions to support and assist each other.

Biologically, humans are mammals.

Human beings are species of the animal kingdom, chordates, vertebrate subphylum, mammals, euzoa, primates, apes, hominidae, hominidae, hominus, hominus, and homo sapiens. It has been scientifically proven that humans originated in East Africa about 5 million years ago. It is a primate belonging to the same family as chimpanzees, gorillas, orangutans, gibbons, and hinged apes.

Mammals are a class of vertebrate subphylum and are commonly known as mammals. Most mammals are vertebrates with a whole body coat, rapid movement, constant temperature viviparity, and diaphragm in the body, and are a group of animals with body structure in vertebrates, so named because they can lactate their larvae through the mammary glands. Mammals can be divided into protozoan subclasses, euzozon subclasses, and posterior zonal subclasses.

Mammals are found all over the world and live a variety of lifestyles on land, underground, in the water and in the air. There are two types of nutrition: grass-fed and meat-fed.

Characteristics of mammals: mammals have a complex body structure, a brain structure, a homeothermic system and a circulatory system that distinguish them from other groups, and have the common external characteristics of breastfeeding offspring, most of them are viviparous, and have common external characteristics such as hair follicles and sweat glands. They range in size from a 30-millimetre-long concave-faced bat with wings to a 33-metre-long fish-like blue whale.

They are well adapted to the environment and are found in a wide range of areas, from the oceans to the mountains, from the tropics to the polar regions.

1. Have a highly developed nervous system and senses, be able to coordinate complex skill activities and adapt to changing environmental conditions, and far surpass other groups in intelligence and response to the environment;

2. Constant temperature (about 25 37), perfect blood circulation system, excellent thermal insulation performance of the body surface hair quilt and other body temperature regulation mechanisms, providing a stable internal environment, reducing dependence on the external environment, different from cold-blooded animals;

3. Viviparous lactation, except for the most primitive monopore oviparous, are viviparous. The higher species form the tissue of mother-child nutrient exchange (i.e., the placenta) between the embryo and the uterine wall. The mother animal breastfeeds and raises the baby for a long time, so that the offspring have a higher survival rate, and the baby animal can also learn to obtain adaptation skills;

4. Oral chewing and digestion greatly improve the intake of energy;

5. Have the ability to move quickly on land.

Of course, as long as there is no shell at birth, not hatching is viviparous breastfeeding. Humans evolved from the forest ape, which is similar to the current chimpanzee, please refer to Animal World for details.

Why humans are not oviparous, but mammals, do you know?

Man is a mammal, mammalian is characterized by viviparity, lactation, and man has the characteristics of viviparity, lactation, and belongs to mammals.

The most important characteristics are: the further development of intellectual and sensory abilities; Maintain a constant temperature; improvement in reproductive efficiency; increased access to and handling of food; There is hair on the surface of the body, viviparity, and hair on the surface of the breastfeeding body, which is generally divided into five parts: head, neck, trunk, limbs and tail.

breathe with your lungs; has a constant body temperature and is a homeothermic animal; The brain is large and well developed. Mammalism and viviparity are the most distinctive features of mammals. The embryo develops in the mother's body, and the mother animal directly produces the fetus.

Sensory

Mammals rely on their highly developed senses to find food, avoid predators, and find suitable habitats, and are also inseparable organs for interspecies communication and a series of behavioral responses. Of course, not all taxonomic senses have reached a highly developed level, and some species are degraded in many ways and highly specialized in one aspect.

For example, some species of mammals with vision deterioration have also developed special high-frequency and low-frequency sound wave pulse systems when they move quickly, and use auditory and sound wave echoes to locate them, such as bats with high-frequency sound wave echolocation, and dolphins with high-frequency and low-frequency underwater sound wave echolocation. This is of great significance in biomimetic research.

Vertebrates are divided into fish, birds, reptiles, amphibians, and mammals. The most basic characteristic of mammals is that mammals are animals with a body coat, viviparous lactation, and internal fertilization, but with the exception of platypus, which is oviparous but is still treated as a mammal after some controversy.

None of the eggs are mammals, mammals are viviparous animals.

All kinds of animal models or toys made by people are not animals.

However, they do show animals!
