Homework Answers
The correct option is e) both a and b.
Natural selection favors phenotype which are better adapted to the environment.
It favors trait having higher chances of survival and reproduction in the given environment.
It is not a random process but mutation is.
It does not lead to perfectly optimal organisms but organisms having traits better suited in the environment.

Which of the following accurately describes natural selection? A) Natural selection acts on pre-existing variation in a population. B) Natural selection occurs when individuals shift to a different phenotype better suited to their novel environment. C) Populations become better adapted to novel environments as individuals with beneficial phenotypes reproduce more than others without that phenotype. D) Two of the above are correct.
