Not exactly. Northeast tiger is bigger than South China tiger, and polar bear is bigger than black bear. There are not many other comparable species, some north and some south, some in the opposite direction. Some are influenced by human domestication and lose comparability. But generally speaking, latitude or temperature is the main factor affecting the difference between north and south. Generally, the higher the latitude, the lower the temperature. Animals need bigger bodies to adapt to the cold and accumulate energy. However, the farther north it is, the bigger it is. This means the northern hemisphere. In the southern hemisphere, in turn, the farther south Leng Yue needs the ability to store fat and energy. But there are more oceans and less land in the southern hemisphere. Therefore, there is no Guang Kun and coherent land for biological reproduction like the northern hemisphere. So the farther south the southern hemisphere is, the less it supports the survival of large terrestrial animals. The living environment near the equator is better. It can't reflect the influence of temperature on biological body shape.
The human body is taller in cold places. This is due to two factors. It's not just the cold that needs to get higher. At the same time, it is also the need for short stature at high temperature. Better adaptability to the environment. This feature is accumulated in the continuation of generations. It can also be reflected in the same generation. It's just that samples need a long time to grow, so it's difficult to control variables for scientific comparison, and the cost is very high. But in fact, the northeast people are relatively taller than Guangdong and Guangxi. And the environment in the northeast can make people grow taller than Guangdong and Guangxi. This is also a comparative feature between Neanderthals in the early morning cold zone and primitive people in Southeast Asia.
Is determined by food factors. For example, most mountainous areas in the north are basically empty, and most of the local surviving animals do not have enough food because of the shortage of food chain, while animal food in the southern mountainous areas is relatively rich. At least giant pandas will learn to eat bamboo, and human survival is just the opposite. The people in the north live in a vast area, and the staple food is mainly grain, while northerners are not picky about food crops. With the extinction of all kinds of animals, human beings naturally become more and more moist. The staple food of southerners is limited to rice, deep mountains and old forests, high temperature and rainy weather, and many animal factors. People who live relatively unstretched naturally look poor and look poor. People who live well will grow more beautiful. This is also evolution. This has a lot to do with climate and food, just as the children born in the north by southern couples are much taller.
In cold regions, organisms have slow metabolism, long growth period and large size, while in hot regions, organisms mature quickly, the growth period is short, sexual maturity is early, the growth period ends early, and the growth will stop soon. But the body has stopped growing, but the sex is very strong, so the biological sexual desire in the hot areas in the south is very strong, which is also a lively feature of the plants and animals in the south.
However, due to the manipulation of natural maturity, wild animals are rich and human nature is lacking, so it is impossible to step into a higher class of human nature and lag behind cold regions.
Because of the strong animality and weak human genes, we can see that human beings in warm areas lack creativity and higher culture.
Only in a difficult environment can human beings be forced to overcome all difficulties and struggle for life. The pressure of this environment will enable human beings to create a life and step into a higher level.
We also see huge animals in the tropics, such as elephants, giraffes and hippos. These animals are not found in cold areas. Isn't it?
There used to be these huge animals in ancient cold areas, with long-haired elephants. However, plants in cold areas grow slowly, and these animals starve to death because of lack of food, while plants in tropical areas are rich and can provide these huge animals with survival, and these animals survived.
Cold regions can only adapt to animals with creative life. They can use fire to keep warm, or make clothes to keep warm. This is human.
But animals will evolve according to the change of environment, and grow long hair to resist the cold, but even the perfect evolution can't escape the killing of human beings, because human beings need a lot of meat to improve their lives.
Today we see the creation of nature, and human beings are created by nature, becoming gods on the earth and ruling the whole world.
Thank you, the question asked by the subject is not objective! That people and animals are different? This is a bit unscientific! However, the growth of plants is different from the height of the north and south! To be clear, people and animals are vertebrates, with similar physiological structures and genes, belonging to the same class of animals, both of which belong to the same class! Unless there are cold-blooded animals and coelenterates! It's just that people have evolved into higher animals! As we all know, all living animals, in high latitude and cold geographical location, their own physiological systems and cell metabolism are relatively slow compared with heat, and in view of the inherent genes of animals themselves, as well as the external temperature determines the size and length of life! Therefore, the colder the geographical location, the less kinetic energy animals pay. In order to resist the cold, your subcutaneous fat storage is thicker! So the bigger the body, the longer the relative life! This determines the size of the animal! So it's not surprising that northerners are taller than southerners! In fact, the same is true of animals, such as tigers, polar bears, yaks and so on. But the subject has not carefully observed it!
When it comes to animals living in the north (high latitude) are bigger than those living in the south (low latitude), people will think of Begemann's law.
According to Bergman's law, under the same environmental conditions, all warm-blooded animals's heat per unit surface area is equal. The straightforward expression is that larger animals have smaller body surface area and volume, so it is easier to keep their body temperature in cold places and prevent the loss of body temperature.
Legend: The Northeast Tiger lives in the northern region, and the picture comes from the Internet.
Logically speaking, Bergman's law is correct. In practical examples, there are also many examples that conform to this law. For example, the northerners in China are bigger than the southerners, and the Northeast Tiger is bigger than the South China Tiger and Bengal Tiger. However, not all species conform to Bergman's law, and the size difference of the same species in different dimensions is not only affected by temperature, but also by many factors.
Are all animals in the south bigger than those in the north? The Siberian tiger is bigger than the South China tiger, and the grey wolf in northern North America is much bigger than the grey wolf in Arabia. These examples obviously don't accord with the fact that animals in the south are bigger than those in the north.
Legend: Compared with the gray wolves living in the north and south, the picture comes from the Internet.
Are the animals in the north necessarily bigger than those in the south? Both African grassland elephants and African forest elephants live in Africa, and the forest elephants living near the equator are obviously much smaller than those living in the plains south of the equator. Among the extinct blade-toothed tigers, the destructive blade-toothed tiger living in South America is bigger than the fate blade-toothed tiger living in North America, and its living area is closer to the equator.
Legend: A tall African grassland elephant, the picture comes from the Internet.
Legend: African forest elephants are small in size, and the pictures come from the Internet.
There are too many examples mentioned above. In fact, although the body shape of animals will be affected by the temperature difference caused by latitude changes, it will also be affected by many factors such as environment and food, thus affecting the size of the body shape. Nature itself is diverse, rich and diverse, and a single law or phenomenon cannot be applied to all living things.
The air in the north is rich in oxygen, and the same plants and animals in the north become shorter in the south, such as koi fish and Taos. We have a couple who came to Wenzhou, Zhangjiakou for a haircut in the 1980s. The male is about 1.7 meters and the female is about 1.5 meters. Eldest brother was born and raised in his hometown in the late 1980s, and now he is one meter seven. Born and raised in Zhangjiakou in 294, he is now one meter eight.
Warm-blooded animals are big in the north and cold-blooded in the south. I finally found out.
Hehe, when you say north, you mean there is a Shandong in Heijiliao. All this was occupied by Russians and Han Chinese a hundred years ago. Don't you find that these four provinces have been shorter than southerners since the founding of the People's Republic of China? This is also related to the previous occupiers.
But in the south, especially in Yunnan, Guizhou, Sichuan, Chongqing and Guizhou, where no one lives, it is much more stable. Even Shaanxi, which belongs to the north, has not been occupied, and the native people are not necessarily much taller than the Sichuanese nicknamed Sichuan Rat. Although Hubei, Jiangsu, Zhejiang, Guangdong and other southern provinces and cities have been occupied, they are different from Heiji Liaolu, so their height is also classified as short.
In modern society, southern China is the frontier of reform and opening-up, and it has introduced many advanced things, such as genetically modified foods and hormones, including animals that eat too much grow naturally.
