Evolution Quiz Review

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

Natural selection results in change over time by acting on traits that are

• heritable
• new
• mutated 
• better than the best

What is another name for natural selection?

• Competiton
• Extinction
• Evidence
• Fossil

Adaptations are:

• physical or behavioral tendencies.

• physical or behavioral characteristics that help an organisms survive and reproduce.

• physical or behavioral characteristics that do not help the organism in any way.

• genetic mutations that have gone wrong.

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

• Because they are more likely to survive and reproduce.
• Because they come from dominant alleles.
• Because they come from recessive alleles.
• Because the trait is an acquired phenotype.

Structures with the same parts have different functions; suggests that organisms share a common ancestry

• vestigial structures
• homologous structures
• adaptive radiation
• fossil

• Dark moth
• Light moth
• Both will be equally successful
• Neither will be successful

Study of embryos of various organisms to show a common ancestor because of similarities in development

• natural selection
• embryology
• speciation
