Question

Explain how a new species or variety can originate through the evolutionary process of natural selection?

Answer 1

Evolution may be a process that leads to changes within the genetic material of a population over time. Evolution reflects the adaptations of organisms to their changing environments and may end in altered genes, novel traits, and new species. The study of evolution is often performed on different scales.

Complete answer:
Natural selection is one among the four basic premises of evolutionary theory, alongside mutation, migration and genetic drift. survival works on populations with a variation in traits, like coloring.
Its main premise is that when there's a trait that permits one individual to survive in an environment than another, the previous is more likely to breed. Survival occurs if four conditions are met: reproduction, heredity, variation in physical characteristics and variation in number of offspring per individual.

Heredity works hand-in-hand with reproduction since the genes of the oldsters combine to make the genes of their offspring. Parents with advantageous traits must pass those traits on to their offspring so as for survival to act. Natural selection can only occur within a population when members of the population have a variation in individual traits. For instance , a study of survival on color within a population requires different individuals to possess varying colors.

Note: So as for survival to act on a given population, that population must reproduce to make a replacement generation. Over many generations, individuals with traits best suited for his or her environment tend to breed quiet people who don't.
