Why is it that the higher the organisms, the less likely they are to develop genetic mutations?

Higher animals are better adapted to nature, and according to Darwin's theory of evolution, the principle of survival of the fittest, genes will develop in a direction that is more suitable for the environment.

Because he has removed many genes in the course of biological evolution.

Because the higher the level of the creature, the better its genes.

Because the totipotency is already low, the differentiation is already good.

Because in the continuous evolution, there is a constant selection of bad genes.

Genes will evolve in a direction that is more suitable for the environment.

The genes of higher organisms are relatively perfect.

Because it's hard for her to change anymore.

Higher animals are better adapted to nature.

This is because they evolved perfectly.

How exactly does evolution work? In fact, many of the evolutionary metaphors we often use are incorrect. For example, it is the entire species, not the individual organisms, that is able to adapt to the environment and evolve. Genes don't want to be passed on to their offspring, genes don't want anything!

1 All hehe, because only genetic mutation can produce change, and only change can determine what advantages or disadvantages the individual has before the change, if that change is more adaptable to the environment, it will be stronger than the original same kind in the competition, and that advantage will be retained and passed on to the offspring, so that the offspring have a more reasonable appearance (and ability) than the ancestors, which is called "evolution".

Sounds a bit like a logic problem, if you find it confusing, you can send me a message and try to explain further.

A gene is a characteristic of an organism, and a gene mutation is a mutation that occurs from time to time, which refers to the change in the genes of an organism, which is different from the previous genes, so why do genes mutate? How does a genetic mutation work? I believe that many friends don't know much about it, so let's find out with me.

Genetic mutation is a "contingency", can it be **? Regardless of whether it is a spontaneous or induced mutation, the mutation is random. It is impossible to predict what kind of mutations will occur in genes and which genes will mutate.

Moreover, any genetic mutation can occur at any time in an organism's life, but the time period during which the mutation occurs has a very different effect on the organism. If there is a mutation in the gene in the zygote, then the mutation in the gene is present in all cells of the organism from which the zygote develops; If there is a mutation in the gene in a cell, then when the cell dies, the mutation disappears.

What causes genetic mutations? Genetic mutations rarely occur in the normal living environment of organisms, but many rays, such as rays, rays, rays, x-rays, etc., will greatly increase the probability of gene mutations. In addition, many chemicals can increase genetic mutations a hundredfold and can also cause chromosomal aberrations.

For organisms, genetic mutations can do more harm than good. For example, some human diseases: color blindness, hemophilia, etc., are the result of genetic mutations.

However, humans also make use of genetic mutations in other organisms for a certain need. For example, the blister-eyed goldfish is the result of a genetic mutation, and the big blister in the eye is useless for the goldfish, which is definitely a burden, but the blister-eyed goldfish meets people's viewing needs, so this species of goldfish can reproduce in large numbers. For example, short-legged sheep are also the result of genetic mutations, short-legged sheep in the grassland because they can't outrun long-legged sheep, often because they can't eat grass and hungry, but for shepherds, short-legged sheep have a smaller range of activity than long-legged sheep, which is easier to manage, so short-legged sheep are also retained by humans.

Causes of gene mutations include the possibility of substitution of base pairs or the addition or decrease of one or more bases; May be caused by radiation; Letterdigging can also be caused by certain slippery nuclear-resistant chemicals. The effect of a genetic mutation is that it causes a change in the order of the bases, that is, a change in the genetic information. The gene is mutated'Causes include the possibility of displacement of base pairs or the addition or decrease of one or more bases; May be caused by radiation; It can also be caused by certain chemicals.
