Most animals have tails. Why don’t humans? Just look at the walking posture!

There are many kinds of animals in nature, such as flying in the sky, running on the ground and swimming in the sea. They have more or less a long history on the earth. They can be regarded as the elder creatures on the earth. They are often distinguished according to the physiological characteristics of these animals. For example, birds have wings to fly in the sky, and mammals live on land to better forage.

Scientists have found that since 500 million years ago, there has been an obvious evolution of body characteristics, that is, the tail. The tail plays different roles in many animals. Take the gecko for example, if it accidentally touches the tail of the gecko, it will directly break off, and soon grow a new tail, mainly to store fat. Birds use their wings to fly more stably in the air, which is very important to birds In most mammals, the tail appears to maintain balance. Since the role of the tail is so great, why do humans stand at the top of the food chain and not grow a tail? It’s not just humans that don’t have tails, it’s even chimpanzees that are close relatives of humans. What’s the matter? Most animals have tails. Why don’t humans? Just look at the walking posture!

The real reason why humans can’t grow tails

First of all, we need to start from the walking posture of human beings. Unlike other animals, human beings walk on their feet. Compared with the animal’s limbs, the feet walk more smoothly and consume much less energy. The most important thing is that the upright walking area does not need the tail to maintain balance. The weight of the upper body is above the lower limbs, which has no direct connection with the tail. Even if the tail grows, its function is very weak, and it will gradually disappear after a long time.

In real life, some babies are born with their own “tail”. This kind of tail is extremely rare. The scientific community calls it atavism. It is actually a kind of pathological tissue, which is a natural defect. Doctors will choose to remove it without harming the baby. Although human beings don’t have tails, they are still obsessed with tails.

Should humans have tails?

Scientists have invented a kind of robot tail, which can swing left and right. Its main function is to maintain the balance of the body, and effectively help the elderly people not fall down easily in the process of walking. The effect is still great. Should humans re install the tail? This topic is highly controversial in the scientific community. Many people think it is unnecessary, but it has become a big burden on the body. Some people think that it will be more interesting to put on the tail. You can imagine that if the tail is relocated, there will be obvious changes in many aspects of life.

While choosing the other half, the length and thickness of the tail should become a big standard. Human beings can control the mobile phone without holding the mobile phone in their hands. They don’t have to hold hands when they go out to play with friends. It’s funny to pull the tail directly. It is undeniable that the existence of the tail has made a tremendous change in human life. Whether this change is good or bad is unknown. After all, everyone has the right to choose. What do you think of the tail? If you are given a chance, do you choose to install it or not?
