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.
E) All of the above are correct.
Homework Answers
E) All of the above are correct.
- Natural selection acts on pre existing variation in a population.
Natural selection always needs some starting material and it acts on the existing heritable variation.
- Natural selection occurs when individuals shift to a different phenotype better suited to their novel environment.
- Populations become better adapted to novel environment as individuals with beneficial phenotypes reproduce more than others without that phenotype.

The sunflower species Helianthus paradoxus, H. deserticola, and H. anomalus all arose from homoploid hybrid speciation between the same two parental sunflower species, H. annuus and H. petiolaris. Yet, the three hybrid species are adapted to the different environments (salt marshes, desert flats, and sand dunes, respectively) in which they occur. Moreover, the three species differ from each other somewhat in appearance and other traits when grown together in a common environment. Which of the following would NOT be a...

6) We discussed the technical parameter, genetic relatedness, in detail, including its specific meaning and its causal impact in the context of the evolution of social behavior. Which of the following is (are) a true statement about genetic relatedness? a. Genetic relatedness describes the statistical probability that an individual piece of design information in one individual is an exact copy of a piece in a second animal by virtue of having been inherited from a very recent common ancestor. b....
