Recently, a very strange fawn in a deer farm in Jilin is on the hot search, we all know that the deer is four legs, but this fawn also grew a leg on the top of the head.
According to the owner of the fawn, this deer farm has been open for many years, but the fawn with one leg on its head is very rare, but now the fawn, although it is 5 months old, is still very healthy, and there is nothing unusual about it compared with other large deer.
Logically, in nature, deformed animals are not rare in fact, but animals with a leg on the top of their heads are very rare, which also makes this fawn deformed very special, so what is the cause?
Why do deformed animals appear?
Speaking of which, whether it is an animal or a human, there will be deformities, but now, with the development of human medicine, because of obstetric examinations, the probability of deformed fetuses has also been greatly reduced. So why do deformed children or deformed animals appear? Let's take human beings as an example.
The first is genetic factors, in general, the human body will have recessive genes, and there will be some bad genes in these recessive genes, which will easily accompany heredity and then appear in the offspring.
What is this concept? To take a simple example, for example, some people will suffer from genetic diseases, but strangely, the family does not seem to have a genetic history, which is actually the same as their parents actually carrying some kind of hereditary bad genes, but because these genes are recessive genes, they do not appear, and in the next generation, this recessive gene becomes a dominant gene, and naturally there are genetic diseases.
The second situation is environmental factors, for example, if affected by the surrounding environmental factors, for example, there is pollution in the environment, etc., it will lead to some infection or poisoning of the mother in the process of conception, thus making the fetus deformed.
Speaking of animals, the same is true of animals, in general, malformations in animals are also caused by genetic mutations, and they are also related to the external environment.
For example, in some high-radiation places, there will be some mutated animals, which look very different from their populations, which is actually the result of receiving environmental influences that lead to genetic mutations.
However, this deformed fawn is not in the environment where it is located, and it is the only fawn in the deer farm that has this situation, so there is also a more bizarre view: this fawn may have absorbed one of its own compatriots.
Was this fawn once twin?
Again, taking humans as an example, there is a very rare case in which some people who are pregnant with twins are stunted because of one of the twins in the mother's body, or because of some other reason, one that causes the stunted one to be absorbed by the other, that is, they are obviously pregnant with twins, but they are born as singles.
In foreign countries, there have been similar situations, there is a couple who gave birth to a child, found that the child's blood type and the two couples are different, of course, this also means that there may be some problems.
Therefore, after investigation, it was finally found that the husband of the couple was originally twins, but when he was in the mother's body, he absorbed another, and as a result, the genetic material of the other was transferred to his body, and by chance, the genetic material of the other was transferred to his child.
Therefore, there is a view that it may be that this 5-legged fawn is due to the absorption of another fawn embryo in the mother, resulting in an extra leg. In simple terms, this fawn should be one of the twins, but the other fawn is not so lucky, but is absorbed by it.
However, at this stage, experts have not given a clear answer as to why this fawn has a leg on its head, so everything is just speculation.
Of course, in nature, in addition to this fawn, there are many animals with 5 legs, or 3 legs, which are also the product of deformity.
It is worth mentioning that with the development of human beings today, the pollution of the earth's environment by human beings is becoming more and more serious, which seems to have led to an increasing number of deformities in animals.
Especially now many people are worried that if Japan really discharges nuclear wastewater into the sea, it may lead to more deformed animals in the future, and even the rate of human deformity will increase, after all, once the genes are destroyed, then, for the earth's organisms, the impact will be very far-reaching, may make the earth's life to a road of no return. What do you think about that?
