The evolution of living things, what is the evolution of living things?

Simply and scientifically, it is the island environment (sea breeze) that selects insects (natural selection), and insect individuals with traits that are favorable to adaptation to this environment (residual wings or no wings) are able to survive (adaptation to the environment) and reproduce genetically; Individuals with unfavorable traits (winged) are eliminated. As a result of the struggle for survival (against the sea breeze), the gene frequencies of insect populations change, and the frequencies of genes that determine the trait of residual wings or wingless are increased, leading to biological evolution (the essence of evolution is the change in the gene frequencies of the population).

Natural selection determines the evolutionary direction of organisms, long-winged insects can fly, but they are easily blown into the sea and drowned on windy islands, while stump-winged insects survive precisely because they cannot fly (survival of the fittest), causing changes in the gene frequency of the population (the essence of evolution is the change in the gene frequency of the population), which eventually leads to this phenomenon.

First of all, the mutation of species is innate, has been going on, and is not caused by natural selection, which should not be confused.

Stump wings or winged, in the end, who is a favorable mutation, who is not a mutation, one is measured according to its survival environment, the island is very windy, so the winged insects are easily injured and not easy to survive. On the other hand, stump-winged insects survive because they can't fly. Eventually, it leads to a directional change in the gene frequency of the population.

It is not surprising that most of the insects on the island are stump or wingless.

The evolution of living things is a very complex process, all of which have gone through a long evolutionary process from simple to complex, from aquatic to terrestrial, from low to high. But this evolutionary process is not smooth sailing, straight up, but zigzag and spiraling, and each of its cycles is a leap forward in the history of biology.

Over the course of history, all animals have changed over time, and this change is a very slow and gradual process, which is called evolution in biology.

Nowadays, many animals no longer exist, because their offspring often mutate under the influence of natural conditions, animals that adapt to natural conditions can survive and develop, while animals that are not suitable for natural conditions are eliminated, this process of survival of the fittest is called natural selection. The remains of those eliminated animals are preserved in the form of stones under the action of the natural environment, and fossils are formed. Fossils are now the main basis for scientists to study paleontology.
