Solution

Evolution:

  1. Evolution is the term used in biology to describe the gradual change in a species' characteristics over many generations as a result of natural selection.
  2. The theory of evolution is predicated on the idea that all species are linked and evolve over time.
  3. The following are the key evolutionary forces:
  4. A mutation is a change in the nucleic acid sequence of an organism's genome, virus genome, or extrachromosomal DNA.
  5. Isolation is a technique in which two species that could create hybrid offspring ordinarily are prevented from doing so.
  6. The act or process of migrating, i.e., moving from one region or habitat to another, is known as migration (gene flow).
  7. Genetic drift is an evolutionary change in a population's allelic frequencies over time as a matter of time.
  8. Natural selection is the mechanism through which people with diverse genotypes survive and reproduce in different ways.
