Question

What is the role of selection and adaptation in the process of evolution?

Answer 1

Evolution is the process of change in characteristic of the species over the generation. It is connected with the natural selection process. During the evolution process, population affects the physical characteristics of the species. Natural selection is the mechanism caused by the evolution process. Adaptation is the physical or behavioral characteristics that make an organism to live in a particular environment comfortably or adapt to live in that place.

Complete answer:
The process of evolution is variation, selection and adaptation. Mutation and recombination of genes may cause the variation in population. If the necessary changes like new survival and reproduction take place then it will accept. Adaptation has two types. One is making a living environment as comfort or because of the selection process it will change their native and accept a new environment. Darwin brings the theory for natural selection. He proposed that some of the variation will cause a good advantage in reproduction and survival for organisms. So this variation is acceptable. So evolution occurs only at the development of new species from the existing species.
Evolution process is based on the four principles. They are variation, inheritance, selection and time. It is called as the components of the evolutionary mechanism of natural selection. Evolution has four factors. There is potential for species to increase in number, genetic variations of individual species because of the mutation and reproduction, competition for the limited resources and ability to reproduce and survive in the environment. Evolution is the process of modern organisms. Natural selection is contrasted with artificial selection.

Note:
Due to the environment change the species that lives in that place will die because of the less adaptation. So the animal that survives in that environment will undergo the reproduction process and produce new species. These new species have different characteristics because they get adapted in the new environment with change in behavior. Natural selection is used to explain the diversity of life on earth. Organisms get the ability to suit their habitat by the adaptation process.
