(2) Natural selection has been discarded as an important concept in evolution.
(3) Changes in gene frequencies due to natural selection have little effect on the evolution of species.
(4) New mutations of genetic material are due to natural selection.

A person with two mutant genes has sickle-cell disease. An individual who has one mutant gene is protected from malaria. A person with two normal genes has perfectly good red blood cells, but lacks resistance to malaria. Is sickle cell anemia a beneficial or harmful adaptation in areas with malaria?
What is a beneficial adaptation

There has been a lot of problems in the middle part of the United States, because all of the water is being used for farming. The fish in this area need the water so that they can survive, but there is a lot of variation in their population. Will the fish stay alive or become extinct?
