The characteristics of each part of various animals, and the characteristics of which animals are po

The question of the characteristics of biological organs is too general, but when it comes to living things, it is basically necessary to mention Darwin.

The Theory of Evolution. Although the biological organs are in different positions, they all play a certain role, following the characteristics of "use in and waste out" in the theory of advancement.

Organs that are used regularly lead to evolution, and organs that are not used regularly will slowly degenerate and lose their original function.

Organs are structures (e.g., hearts, kidneys, leaves, flowers) composed of different cells and tissues of animals or plants, which are used to perform certain functions and form various systems together with other structures that share common functions. The organs of the plant are relatively simple, the highest angiosperms.

There are six organs: roots, stems, leaves, flowers, fruits, and seeds, and other plants do not have these six organs. The organs of animals are so complex and so numerous that it is difficult to list them specifically.

Each organ of an animal or plant has different characteristics, such as the animal's foot, which is characterized by the fact that the contact part between the bottom and the ground varies depending on the environment, upholstery, hardening, etc., and the foot itself has a certain balancing effect, and must have a strong Achilles tendon.

and foot bones.

For typical anatomical knowledge, go to the veterinarian's anatomy books. I know about animal anatomy, small animal anatomy, poultry, etc. Give points, such a big problem is difficult. It seems that veterinarians also have local anatomy, histology, etc. that may be helpful to you.

1. Fish.

Characteristics: Aquatic animals (can only live in water). **Covered with scales, it is an ectothermic.

An ectotherm animal that has fins (can swim in water) and breathes with gills. In vitro fertilization, mainly oviparous, partly viviparous and ovoviviparous.

The larvae breathe with gills, while the adults breathe with **, the inner wall of the mouth and the lungs.

3. Reptiles.

Characteristics: Terrestrial animals. **Covered with scales or shields, with a waterproof outer skin, water loss, ectotherm (dependent on outside temperature or heat sources to change its body temperature).

It is mainly found in warmer parts of the earth. In vivo fertilization, oviparous or ovoviviparous. The eggs are laid on land, and the eggs are covered with a waterproof outer package.

4. Birds. Characteristics: The whole body is covered with feathers, the body is streamlined, and there is a beak. The eyes are on both sides of the head, and the neck is long and flexible and can be turned 270 degrees.

The forelimbs are specialized into wings, and the hindlimbs have a scaly outer skin with four toes. Homeotherms (they can generate heat through their own physiological processes, and they can maintain a high and constant body temperature even when the outside temperature is low). The average body temperature is about 10 degrees higher than that of mammals (42 degrees on average) and is oviparous.

5. Mammals.

Characteristics: There is a spine in the body that is made up of many vertebrae connected by it; The body is covered with hair, and there is oral chewing and digestion, which can improve energy and nutrient intake; viviparous (except platypus, except echidna), lactating; Constant temperature. The body temperature can also be kept relatively constant when the ambient temperature changes, which reduces the dependence on the external environment and expands the distribution range.

The brain is enlarged, the brain is quite developed, and it surpasses other animals in intelligence and adaptation to the environment; The inner limbs are strong and sensitive, with rapid mobility; The left and right chambers of the heart are completely separated; Teeth are divided into incisors, canines, and buccal teeth.

The Chinese dragon is a kind of sacred object produced by the ancient people's vague collection of fish, crocodiles, snakes, pigs, horses, cows, deer and other animals, as well as natural celestial phenomena such as clouds, thunder and lightning, rainbows, and tornadoes. The fuzzy assembly process of dragons originated from the development and prosperity of primitive society, that is, the transition from the gathering economy to the production economy and the widespread worship of gods in the early Neolithic period, and has a history of about 8,000 years.

The formation process of the Chinese dragon is the same as the process of the pluralistic integration of the Chinese nation. In ancient Chinese myths and legends, the dragon may be the creation god who opened the world, and is as famous as Pangu; or actively participated in the marriage of Fuxi Nuwa, thus reproducing human beings; or helped the Yellow Emperor win the war of unification; Or assist Xia Yu in controlling the flood and benefit future generations. Therefore, in view of the inseparable relationship between myths and legends and the origin of the nation, it can be said that all the descendants of Yan and Huang and the sons and daughters of China have received the blessings of the dragon and can be called "descendants of the dragon".

The spirit of the dragon is the spirit of unity and cohesion, the spirit of benefiting mankind, the spirit of striving for pioneering and the spirit of harmony with the sky.

Loving water, being good at flying, reaching the sky, fickle, Zhengrui, omen, and demonstrative, are the basic divinities of the dragon. After entering the class society, the dragon added to the body the divinity that symbolized the imperial power. The changes of the times, the transmutation of civilization, and the impact of modernization have weakened the divinity of the dragon symbolizing the emperor's power and the divinity of the omen and demonstratives.

The land of China is the homeland of the dragon and the home of the dragon. Dragon culture has penetrated widely into all aspects of social life. Whether it is arts and crafts, architectural attractions, singing, dancing, film and television, or the season, wedding and funeral etiquette, clothing and crown shoes, the dragon as an important part, in the form of hovering, leaping, flying, etc., occupies a striking position, reflecting the indispensable cultural implications.

The dragon is a mythical animal in ancient myths and legends in China and other East Asian regions, and it is the chief of scale insects. It is often used to symbolize auspiciousness, and is one of the most representative traditional cultures of East Asian peoples such as the Han nationality, and the legend of the dragon and other dragon cultures are very rich.

In Chinese myths and legends, it is a supernatural animal with a snake body, lizard legs, eagle claws, snake tail, antlers, fish scales, whiskers at the corners of the mouth, and beads under the forehead. "On Balance" says: "The image of a dragon, the head of a horse and the tail of a snake."

Others say that the shape of the dragon is the antlers of a deer, the ears of a cow, the head of a camel, the eyes of a rabbit, the neck of a snake, the belly of a mirage, the scales of a fish, the soles of the feet of a deer, and the claws of an eagle.

On some ancient buildings, we can often see the image of the dragon: on the Huabiao in front of the Forbidden City, the cloud dragon stepping stone behind the Baohe Palace, there are dragons with teeth and claws, especially the nine dragon walls in Beihai Park in Beijing, made of stained glass bricks, 5 meters high, thick meters, 27 meters long, there are nine dragons on each side, playing with pearls in the waves and clouds, it is a fine product in the ancient building. In some myths about dragons, it is said that it can overturn rivers and seas, soar clouds and fog, call for wind and rain, control droughts and floods in the world, and act as a blessing ...... willIn feudal society, the emperor compared himself to the embodiment of the dragon, that is, the "true dragon son of heaven", and even embroidered the clothes worn by the emperor with a dragon, called "dragon robe".

There are also folk customs ...... of "dragon lantern dance" and "dragon boat racing".Are there any dragons? If it does not exist, how is it "created"? Around 1940, Mr. Wen Yiduo clearly pointed out:

In fact, there are only snakes and chickens in the biological world, so how can there be dragons and phoenixes? "It is now generally believed that the dragon is a supernatural animal with scales and mustaches that can make clouds and rain in ancient legends.

However, although the "dragon" is a product of the imagination of the ancients. But it must have been based on the imagination of one or more animals in the first place. The word "dragon" in the oracle bone inscription has a large head, a large mouth, a long and curved body, and tattoos on the body.

These traits have in common with snakes, crocodiles, lizards, etc. Therefore, it is believed that the dragon referred to at that time was the serpent; Some people think it's the Chinese alligator; Others believe that people may not have understood the characteristics of animals at that time, and called several uncommon reptiles dragons. Later, the mythological color of the "dragon" became stronger and stronger, and the more it was said, the more mysterious it became, but it still used reptiles as the basic image.

"The dragon was born in the water and was swam by the five colors, so the gods. If you want to be small, you are like a silkworm, and if you want to be big, you can't hide it in the world; If you want to go up, you will be above the clouds, and if you want to go down, you will go into the abyss.

It is also said in the essay (written by Xu Shen of the Eastern Han Dynasty): "The dragon can be dark and bright, small and huge, short and long." The spring equinox ascends to the sky, and the autumn equinox dives into the abyss.

Although these statements are all mythological renderings, they may be analyzed with the knowledge of modern zoology: "dragons" have scales on their bodies, and sometimes they shine; It may be a matter of breathing, and the body seems to be thick or thin; Because of the winding crawling, it makes people feel the length of the look; Not coming out in winter, maybe hibernation - these phenomena are all ecological characteristics of reptiles such as snakes, lizards, crocodiles, etc. Later, the mythical color of the dragon became more and more intense, and the body structure became more and more complex, so that the image of the dragon we usually see today is a monster made up of antlers, hump heads, rabbit eyes, bull ears, snake bodies, mirages, fish scales, eagle claws, and tiger paws.
