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

To adjust to a changing environment, living things must

• Mutate

• Adapt

Darwin wrote that organisms with traits that are best suited to the environment will ________________

• increase in number
  
• become extinct

Some organisms that share a common ancestor have features that have different functions, but similar structures.  These are known as

• vestigial structures
• analogous structures
• homologous structures
• fossil structures
