A physical trait favored by an environmental change can be called an (a)  

• adaptation
• extinction
• possibility
• mutation

According to the theory of natural selection, why are some individuals more likely than others to survive and reproduce?

• Some individuals pass on to their offspring new characteristics they have acquired during their lifetimes.

• Some individuals are better adapted to exist in their environment than others are.

• Some individuals do not pass on to their offspring new characteristics they have acquired during their lifetimes.

• Some individuals tend to produce fewer offspring than others in the same environment.

In natural selection, the selective agent is the

• humans
• mutations
• breeders
• environment

Mutations are important because they bring about

• death of the organism in which they develop

• genetic variation needed for a population to evolve

• benefits for the individual, not for the population

• Hardey-Weinberg equilibrium within a population

Genetic drift is change in the allele frequency of a population due to...

• random chance

• natural selection

• non-random mating (sexual selection)

• artificial selection

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

• individual
• population
• species
• fossil

A type of genetic drift in which small groups of organisms separate from a larger population and form new small colonies.

• Gene Flow

• Founder Effect

• Natural Selection

• Artificial Selection
