Charles Darwin & Natural Selection

Which of the following is the term for a group of similar organisms that can reproduce fertile offspring?

• individual

• population

• species

• fossil

According to Darwin’s theory of natural selection, individuals who survive are the ones best adapted to their environment. Their survival is due to the

• possession of adaptations developed through use.

• possession of favorable, inherited adaptations that maximize fitness.

• lack of competition within the species.

• choices made by plant and animal breeders.

Why are advantageous traits more likely to be passed on to offspring?

• Because they come from recessive alleles.

• Because the trait is an acquired phenotype.

• Because they come from dominant alleles.

• Because they are more likely to survive and reproduce.
