Did the tail disappear abruptly or gradually during human evolution?

This is an interesting question. First of all, I think the human tail disappeared in the process of evolution. Why?

Let's discuss it together. Human evolution has always been fraught with controversy about human evolution, because among the fossils found now, there are no fossils of various stages of human beings, that is, no fossils have been found that have played a key role in human evolution. This has become one of the reasons why many people doubt the theory of evolution.

It seems to me that as science develops, many mysteries will eventually be solved, and many plausible claims may be overturned. But until there is a more plausible explanation, the theory of evolution remains a scientific argument for the origin and development of species.

From an evolutionary point of view, humans evolved from apes, and apes evolved from ancient primates. According to the fossils found now, the earliest primates appeared in the early Paleocene 56 million years ago, that is, after the extinction of the dinosaurs, ancient primates appeared. This primate is considered to be the common ancestor of all primates.

From the point of view of the stone, this early primate eye structure was still located on the sides of the face, rather than facing forward as in today's primates. Based on the bone structure, scientists deduced that it was not as good at jumping as the primates of today. But it has a long tail.

To put it simply, the process of moving from ape to man is a change in walking posture and form on the surface.

From crawling to walking upright, from ape to man. Most animals in nature have tails, such as cows, squirrels, leopards, scorpions, and many more. Then let's take a brief look at what these animal tails do.

Oxtail is used to repel mosquitoes and protect the anus. The squirrel's tail not only helps it balance in the tree, but also acts as a cushion when jumping from a height and landing. The tail of a leopard is mainly used to maintain the balance of the body, and the tail of a scorpion is mainly used as a defense and attack.

After a person stands and walks, the well-developed cerebellum has a good effect on maintaining body balance, liberating the forelimbs when standing, which can not only play a cushioning role when the person falls to the ground, but also grasp objects for defense and attack. The tail is very chicken for people.

In fact, the process of purchasing goods is to disappear slowly, not suddenly, and then finally it is the process of forming a tail without a tail, so it has also experienced this change in the previous year.

Due to the continuous changes in the environment on the earth, in order to adapt to this change, human beings change to a state suitable for human development, and in this process, the round tail gradually becomes shorter, and the later disappears, just like the evolution process of frogs, frogs are still in the tadpole period, there is a tail, and when the limbs gradually grow, the tail gradually becomes shorter, until there is no more, and the evolution of human beings is the same, the tail is gradually disappearing, not suddenly disappearing.

There has never been a tail, and there is nothing that disappears or does not disappear, because it does not necessarily evolve from monkeys with tails.

It is gradually disappearing, because of the process of human evolution, many changes are carried out step by step.

In the process of human evolution, the tail has lost its useful function to the human body, so it is degenerate, the main function of the tail for animals, mainly has the role of balancing the body, repelling mosquitoes, **, etc., such as the tail of birds in addition to helping the body balance when flying, ungulates are mainly to repel mosquitoes, almost no balancing effect; Tiger and crocodile tails can also be used as attacks**. The leopard's tail is mainly used to help steer while running. The human tail has degenerated.

There are not many mammalian species that do not have tails. However, the species most closely related to humans do not have tails. Therefore, evolution has long lost its tail long before we are born.

There are also short-tailed bears, so animals that walk more on their feet than on all fours are less dependent on their tails, and their functions gradually deteriorate. Humans, orangutans, and bears, in particular, often sit. So the tail is of low use, and it is degraded.

Humans are one of the few animals that do not have a tail, of course, you can also say that humans have a tailbone, and there are very few cases, babies will have tails, in fact, that is not a tail, that is just the remains of an embryo, a false tail, is covered with a false tail containing muscles and blood vessels, as well as connective tissue, but he has no bones and cartilage, so it cannot be connected to our spine and is usually removed. So what other animals don't have tails?

If you pause for a moment, it may be difficult for you to think of any animals that do not have tails, of course there are many, like many insects, snails, spiders, snakes, in fact, they all have no tails, praying mantises, starfish, butterflies, gorillas, chimpanzees, ants, dragonflies, bees, mosquitoes, koalas, etc., but no tail only constitutes a small part of animal biology. As you might expect, there are very few animals that don't have tails. Why is that?

The tail plays a balancing role in many animals.

Because humans have always lived on the ground, if they have a tail, it will be very troublesome to do anything, which will affect the normal life of human beings, and humans have no natural enemies, and the tail has no effect, so the tail will disappear slowly.

It's because it's often not used, so it gradually degenerates, and gradually disappears, because the tail has no effect, so it will degenerate.

It is in the process of development that the tail does not play its due role, affects people's actions, and then degenerates.

Because the tail is for humans,It doesn't work at all, so it slowly degenerates, for example, among animals, fish need to use their tails to swim, and monkeys and squirrelsThey mainly live in trees, so the tail is mainly used to maintain the balance of the body so that they will not fall, but after humans evolved from monkeys, they basically moved on land, and they did not need to use the tail to maintain balance, and the tail was just a burden for humans.

Everyone knows that human beings are a relatively advanced animal in evolutionCompared to most animals, human beings have much better IQ and hands-on ability than other animalsAnd in addition to humans, it is the most advanced in the evolution of mammalsBut most mammals still have tails, while humans don'tMany people wonder why humans have taken their tails back in the process of evolution, because monkeys sometimes have long tails, and the reason why humans don't keep their tails is because tails don't have any role for humans.

First of all, the tail of most animalsIt is not an ornament, but has a meaning of existence, for example, the tail of a tiger can be used as an attackIn the case of monkeys, the tail can maintain balance in its movementsso that they do not fall, but humans generally walk and run, not crawlTherefore, the tail is used for human beings, there are very few places, as for the use of the tail as **, this is more common in felines, humans themselves do not rely on predation for a living, even if it is a hunting animal, it is also relying on tools, so it is even more impossible to use the tail as **.

And humans don't live in trees anymoreLike monkeys and squirrels, they live in trees and need their tails to maintain balance or immobilize their bodiesBut humans now live on the ground, and tails have become a burden for humansSo the tail of human beings slowly disappeared in the process of evolution, just like many fish evolved to live on the shoreThe gills will gradually disappear and be replaced by respiratory breathing in the lungs.

According to Darwin's theory of evolution, natural selection is dead. Use the rules of the game to encircle all the creatures. After humans are able to walk upright, they do not need their tails to maintain the balance of their bodies, and they gradually degenerate and shrink. This is the result of the survival of the fittest.

Because humans have learned to use their hands and walk upright in the process of evolution, the tail has become less important. According to natural selection, the law of survival of the fittest, things that are not so important will naturally be eliminated, so human beings have no tail.

In fact, this phenomenon is also very easy to explain, that is to say, the organs that human beings use in the process of planning will become more and more developed, such as the organs of our hands and feet that have not been used, then they will slowly degenerate.

The tail is mainly to fix the body, maintain balance, and occasionally do the ** of attack, however, after humans come to live underground from the tree, they do not need the tail to fix the body and the balance effect of the arms is far more than the tail, and humans have learned to use tools, and do not need to use the tail as **. To put it bluntly, this is a phenomenon of "abolition".

The sand on the planet is running out, why is there so much demand for sand! Knowledge.

Humans belong to a group called apes. Chimpanzees and gorillas do not have tails, and other small apes like gibbons do not have tails either. By observing these primates, scientists have discovered how the absence of a tail is an advantage

In the treetops of Southeast Asian forests, gibbons can use their long arms to swing from branch to branch. As they swing forward, the torso and legs hang underneath to keep the body upright. At this point, the tail only gets in the way of things and movements.

In addition, gibbons without tails do not lose their balance. They can walk on branches with their arms and feet. The upright posture without a tail is also great for climbing tree trunks.

The function of ape's tail is the focus of balanced limb running or tree survival activities, which is conducive to ape's flexible survival activities. Since the establishment of the upright walking survival activity model, ape tails have become a redundant waste of the upright walking survival activity of apes because they are not used. Over time, their tails will gradually decline until they disappear completely.

This is to follow the principle of "use in and waste out" in animal evolution, that is, the functional cell tissues that animals often need to use will continue to proliferate and develop, and continue to evolve and improve; "Waste" means that the animal loses the function of the original cell tissue (tail) due to ecological changes. If they are not used, they form excess waste products in the body and gradually degenerate until they disappear completely.

In fact, most mammals have tails that are used to keep their balances, and apes are no exception, but note that they need to keep their tails balanced, and humans don't need to walk on their feet。This still needs to be analysed from an evolutionary point of view. The tail is a part of the body.

It needs exercise, so it needs energy expenditure. You know that there is a lot of natural selection in the evolution of human beings. Thus, some people who do not have tails gain an advantage in natural evolution because they consume less energy, so people who do not have tails today.

The tail is gradually degraded in the process of human evolution, because the tail has less and less effect on humans. Because humans have been adapting to their environment during evolution, they disappear.

Exactly how humans degenerate their tails has always been one of the questions of great interest to scientists. Recently, scientists have discovered a skipping gene associated with tail growth, which they believe may have entered other parts of the primate genome millions of years ago, and that the mutation in the gene produced by this change directly led to the disappearance of the human tail.

What many people don't know is that when we were only in our mother's womb for a few weeks, we also had a tail for a short time. The tail is actually one of the characteristics of the first vertebrates on earth, when we were still embryos, we had tails and vertebrae like all vertebrates, but after eight weeks, the tail disappeared.

In 2008, scientists explained this phenomenon in the journal Nature, believing that it is a loss of apoptosis, a kind of programmed cell death in the development of multicellular life.

Mainly in the process of evolution, the tail loses its effect on humans so it slowly disappears, whether it is a human or an animal, there will be some unwanted organs degenerate during the conversation.

It is because the tail of man is becoming less and less used in the process of evolution, because he lives on land and does not need to use his tail to swim, so it will slowly disappear.

Class tails, such as degeneration, have always been one of the topics of scientific interest. Science has recently discovered a skipping gene associated with tail growth, which is thought to have been transferred to the genome of primate species millions of years ago.

If we look at it according to the theory of evolution, why did the tail disappear when humans evolved? People evolved into monkeys, and monkeys are the ancestors of our humans. This seems to be an understanding of the average person.

But many people have an opinion, saying that monkeys have tails, we don't have tails. We will not evolve by monkeys, we will evolve by orangutans. It's time, what are the ancestors of orangutans?

Some experts say that we are closest relatives of orangutans and that our common ancestors were ancient monks. The question is what were the ancestors of the ancient monks? I think it's finally around the bend.

This is our ancestor, and I am just beginning to tail. I don't know how to lose it. Our ancestors turned into the ancient Bakai.

Haha, run, and then we'll start with our tail, "a monkey, of course." An evolutionary-based view of genetic variability survival. It should have been a long time ago, due to a genetic mutation, there was a monkey, a monster:

There is no tail, but the monkeys are very strong and have a high IQ and have many offspring without tails. However, no tail was discriminated against tails, and then they formed a population without tails, which are now the ancestors of humans and comrades. Later, it evolved into humans.

The theory of "use in and out" shit did not pass, what tail does not need to degenerate, I wonder when there is no tail there is a tail ratio, and the power is: you can be ashamed, you can keep your body balanced, you can catch flies, you are bored when you play on your own, why do you downgrade? Due to a genetic mutation, the tail is lowered, and it is a natural disaster!

There is no need to connect with an evolutionary adult without a tail, and a gorilla without a tail? The monkey turned into a genetic mutation that coincided after countless chances and eventually evolved to a human with a very low probability.

So everyone should cherish their time as a human being, learn every day, and constantly strive for our genetic strengths. Finally, to return to the topic, if humanity now had a tail would be: we would be happier, many of humanity's sports records would be broken, humanity would be more flirtatious, and humanity's clothing design would change the earth's shaking changes.
