Is Natural Death an Evolutionary Necessity?

Natural death is not an evolutionary choice, but an inevitable consequence of life. Adaptive change is the ability of organisms to continuously adapt to changes in the environment, and nature will select various mutated individuals, and those who are not selected will die.

Not an evolutionary necessity, but a natural consequence, no matter what happens, there will be a day of death.

Yes. Because the resources in nature are finite and cannot be infinitely the survival of ** creatures, natural death is an inevitable choice for evolution.

Natural selection is the selection of environmental conditions or other organisms for a certain organism, and the altered environment is a selection factor, not a mutagenic factor of biological variation.

Before the environment changes, there are variations in organisms, some variations are beneficial to the survival of organisms, and some variations are not conducive to the survival of organisms, that is, variations are not directional. The role of natural selection is to preserve and pass on the mutated genes that are beneficial to the survival of organisms to their offspring, and some of the mutated genes that are unfavorable to survival are gradually eliminated, which leads to directional changes in the gene frequency of the population, so that the organisms evolve in the direction that is beneficial to survival.

I think so. Nature follows the principle of survival of the fittest, and through death it is possible to eliminate those who cannot adapt to nature.

The higher the animal, the lower the ability to regenerate and immortalize, like the turtle has a long lifespan, and death is a prerequisite for evolution.

It's just a law of nature, anyway, I haven't heard of getting younger and younger.

If there are creatures that can exist forever, then the earth will become more and more crowded.

Nothing can be immortalized, and death is not the result of evolution, but the result of having to be experienced.

Birth, old age, sickness and death, this is the natural law of nature, and this cannot be resisted.

If all living things could live forever, the earth would not be able to withstand the pressure.

Because there are always new species emerging, and if they keep surviving, the earth will not be able to load.

New species emerge, and if they keep alive, the Earth will not be able to load.

Because this is a law of the world's existence. Over time. Survival of the fittest has evolved.

If human beings don't die, then the world will be chaotic and will always be ruled by one person, so what's the point, the survival of the fittest.

Today, let's talk about why life evolved the function of death?

The meaning of natural selection is: the phenomenon of survival of the fittest and the elimination of the unfit in the struggle for survival.

Darwin's theory of natural selection has four main points: overbreeding, the struggle for survival (also called survival competition), heredity and variation, and survival of the fittest.

Biological evolution to the point that human beings will not stop evolving, and those who cannot be fittest societies will also be eliminated, so human beings are also constantly evolving.

It will not stop, people are constantly evolving, survival of the fittest.

The meaning of natural selection is natural selection, and the evolution of organisms to humans is only one part of it.

The theory of evolution is the second major scientific breakthrough in human history. For the first time, heliocentrism replaced geocentrism, which denied the arrogance complex of human beings at the center of the universe; The second is the theory of evolution, which pulls human beings to the same level as ordinary creatures. All the creatures of the earth have a distant or close blood relationship with human beings, completely breaking the ignorant self-esteem of human beings who are arrogant and arrogant, under one god and above all beings.

The theory of evolution is a systematic scientific theory that takes history as a mirror to find out the laws of life and the direction of development, and is a hypothesis about the origin and development of life. In the ancient Greek period, there were some sporadic evolutionary ideas, including the current "evolutionist" evolutionary theory that has no direction and is reasonable, and it is not a systematic scientific theory.

Most of the evolution of the 21st century is based on molecular phylogeny and evolutionary dynamics "based on molecular clocks, evidenced by the protein pam matrix and the amino acid matrix of blosum", guided by Darwin's theory of evolution. With Erwin Schrödinger's "What is Life" as the main direction, near-neutral mutation as the framework, it has become one of the core ideas of contemporary biology, explaining genetic changes such as chromosomal equilibrium translocation. Whereas, Darwinian evolution mainly refers specifically to the view of evolution in Darwin's time.

The theory of natural selection mainly includes the following three harmonious and unified contents: (1) the theory of survival struggle. The contradiction between excess reproduction and limited living conditions is one of the external reasons for the elimination of species on Earth.

2) The theory of hereditary variation. Although the mechanism of variation is not clear, the fact that variation is widespread is undeniable, and Darwin used it to explain the intrinsic reasons for the evolution of species. (3) The theory of survival of the fittest.

The conditions of existence are always changing, and if the variation of the species is adapted to the changing environment, then it will develop victoriously in the struggle for survival; If the species is not adapted to the conditions in which it is alive at that time, then it tends to decay or perish.
