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

When two organisms evolve in response to each other because they live in a close mutualistic relationship or when one organism mimics another organism that is called

• Speciation

• Coevolution

• Gradualism

• Convergent evolution

Which pattern of evolution results in one species with a common ancestor splitting into many over time?

• Convergent evolution

• Sexual selection

• Coevolution

• Divergent evolution

Organisms that live in similar environments, such as the ocean, often have similar adaptations without a common ancestor. This is often due to....

• Gradualism

• Coevolution

• Convergent evolution

A population of bacteria is treated with hand sanitizer. Because of genetic variation in the population, what is a possible outcome?

• Some may naturally be resistant and survive

• They will get better at obtaining a food source

• The population will grow quickly

• All of the bacteria are already resistant

Genes for traits that help an organism have greater fitness can be expected to....

• Cause it to evolve into a new species

• Eventually be eliminated by natural selection

• Cause the extinction of the species

• Become more common in future species
