Question

What is the law of natural selection?

Answer 1

Darwin was the first person to employ natural selection. He discussed the species' commonalities as well as their differences. Variation is the term for these differences. Natural selection refers to the process through which nature chooses the most suited and fit organisms for evolution. The organisms in nature face some difficulties. Climate change, food scarcity, and natural disasters such as floods, lightning, and earthquakes are examples of these difficulties. Features are present in all species, and these characteristics can be game-changers for some creatures during evolution.

Complete answer:
The law of natural selection explains how plants and animals adapt to changes in their environment so that they can live and reproduce.
The two reasons for evolution, according to Darwin's Theory of Evolution, are branching descent and natural selection. Climate, temperature, resource availability, and other environmental factors all played a role in the evolution process.
Inheritance is another aspect that can contribute to natural selection. For the same resource, two creatures compete. They will dominate the other if one can multiply significantly quicker than the other. As a result, the hereditary gene in organisms aids selection and evolution. To put it another way, the more you adapt to the changing environment, the better your chances of being chosen by nature.
Inadequate climatic variations, natural resources, predators, competition, and other obstacles posed by nature to choose the fittest are incredible hurdles. Those that have more inherited adaptations will have a better chance of surviving, while others will struggle. Nature's chosen ones will grow, reproduce, and a new population will emerge at the expense of others.

Note:
Evolution is the process through which modern species descended from their ancestors with changes in allele frequencies.
Evolution is triggered by changes in the gene pool (the collection of genes). There are four basic mechanisms that drive a population to grow. These are some of them:
Mutation.
Gene Flow.
Genetic Drift.
Natural Selection.
