Natural selection is a process where organisms that are better suited to a certain set of environmental conditions tend to survive and reproduce more often than others. This leads to evolution as the traits mutate into other traits. organisms with those traits appear less often in the population. the environment changes fast enough to prevent overpopulation. organisms with those traits appear more often in the population. organisms with different traits appear more often.

Natural selection is the idea that…a. the fittest organisms will surviveb. individual organisms that are best suited to their environment will leave most offspring and their genes will spread through the population in future generationsc. gene frequencies change through timed. species change through timee. traits that are best suited to the environment will be favoured in individuals

Natural selection occurs only if there is both (1) variation in the genetic information between organisms in a population and (2) variation in the expression of that genetic information—that is, trait variation—that leads to differences in performance among individuals. What kind of variation might exist in bioluminescent organisms, and what differences in performance might result? (Remember, evolution is a consequence of the interaction of four factors: (1) the potential for a species to increase in number, (2) the genetic variation of individuals in a species due to mutation and sexual reproduction, (3) competition for an environment's limited supply of the resources that individuals need in order to survive and reproduce, and (4) the ensuing proliferation of those organisms that are better able to survive and reproduce in that environment.)

It seems logical that natural selection would work toward genetic uniformity; the genotypes that are most fit produce the most offspring, increasing the frequency of adaptive alleles and eliminating less adaptive alleles. Yet there remains a great deal of genetic variation within populations. Describe factors that contribute to this variation.
