What is a bioadaptation strategy

As for the adaptation strategy, Darwin's theory of natural selection explains the diversity and adaptability of organisms relatively systematically.

Natural selection is the process of environmental conditions to select for the mutation of organisms, resulting in the survival of the fittest and the elimination of the unfit. In the process of evolution, the number of organisms that are more adapted to the environment will increase if they are more able to survive and leave more offspring and individuals, while the number of organisms that are not adapted will decrease.

Darwin believed that in the struggle for survival, individuals with favorable variation are more likely to win and survive in the struggle for survival. On the other hand, individuals with unfavorable mutations are prone to defeat and die in the struggle for survival. That is to say, all the organisms that survive are adapted to the environment, and the organisms that are eliminated are not adapted to the environment, which is the survival of the fittest.

Introduction to Biological Examples]:

There is a species of birch moth in England, which was of the grey type until 1850. In 1850 a black mutant was discovered in Manchester. In the second half of the 19th century, with the development of industrialization, the HS in the exhaust gases killed the gray lichen on the bark of the tree, and the soot smoked the trunk black.

As a result, the gray type, which was previously protected from resting on lichens, is now vulnerable to bird predation on black trunks; The black type, on the other hand, survives and thrives because of the cover of soot and protection from bird predation. As a result, the number of black types is rapidly increasing, while the number of gray types is decreasing. By the end of the 19th century, the former had risen from less than 1 to more than 90; The latter dropped from over 90 to less than 5.

The results showed that natural selection had developed a black mutant type of birch moth adapted to the new environment by retaining the beneficial gene individuals and eliminating the unfavorable gene individuals.

Starting from biological adaptation, from the perspective of ecological adaptation, this paper discusses the significance of biological adaptation and the choice of survival strategiesEcological adaptation always refers to the combination of adaptation to a certain set of environmental conditions, that is, the beneficial results obtained by an organism in the interaction with the changed environmental factorsIf a species adapts well to its environment, it can survive in that environment and reproduce effectively; As far as evolution is concerned, reproductive success is the main measure of how well an organism adapts

Organisms' adaptation to the environment is not perfect, and there is a cost of adaptation; Since the physical and biological environment is always volatile, adaptation is constantly subject to the fine-tuning of natural selectionIn nature, the adaptation changes of organisms are mainly quantitative changes; Under changing environmental conditions, it is often manifested by changes in the intensity and speed of physiological processes and in terms of individual morphological quantity and traitsAdaptation to the external environment is the basis of internal variation in species, and under the condition of the participation of new environmental factors in metabolism and the semi-lethal selection of environmental factors, the quantitative change of biological adaptation can develop into qualitative change, change the attributes of the species and produce new adaptations that are completely different in nature

Biological evolution inevitably follows the thread of ecological adaptation; The adaptation of organisms is to maximize the benefits of the survival and reproduction of organismsHope.

Start with biological adaptation.

From the perspective of ecological adaptation.

Discuss the significance of adaptation and the choice of survival strategies in organisms.

Ecological adaptation always refers to the combination of adaptations to a certain set of environmental conditions.

That is, the beneficial results obtained by an individual organism in the event of interaction with a changed environmental factor for that species.

If the species is well adapted to its environment.

It will be able to survive in that environment.

And it can reproduce effectively.

As far as evolution is concerned.

Reproductive success is the main criterion for measuring the quality of adaptation.

The adaptation of living beings to their environment is not flawless.

There is a cost to adaptation.

Because the physical and biological environment is always fluid.

So adaptation is constantly subject to the fine tuning of natural selection.

In nature. The adaptation changes of organisms are mainly quantitative changes.

under changing environmental conditions.

It is often manifested by changes in the intensity and speed of physiological processes and in the morphological number and traits of individuals.

Adaptation to the external environment is the basis for variation within species.

Novel environmental factors involved in metabolism and environmental factors are semi-lethal under the conditions of selection.

Only quantitative change in biological adaptation can develop into qualitative change.

in order to change the properties of the species and produce new adaptations that are completely different in nature.

Biological evolution inevitably follows the thread of ecological adaptation;

The adaptation of organisms is to maximize the benefits of the survival and reproduction of organismsHope.
