How does natural selection work regarding individuals and populations?
Natural selection is the process through which populations of living organisms adapt and change.
Individuals in a population are naturally variable, meaning that they are all different in some ways.
Individuals with adaptive traits—traits that give them some advantage—are more likely to survive and reproduce..
Could natural selection work on a population with no variation?
Natural selection can only occur if there is variation among members of the same species.
Does natural selection act on a population?
Natural selection is one of the ways alleles can change in a population. … The thing is, natural selection works on a population over generations because individuals that do better in the environment (we would say they are favored by natural selection) tend to have more babies, causing changes in the gene pool.
What is required for natural selection to occur in a population?
Four conditions are needed for natural selection to occur: reproduction, heredity, variation in fitness or organisms, variation in individual characters among members of the population. If they are met, natural selection automatically results.
