Which of these descriptions is an example of an unused body structure?

• a bat’s wing that enables it to fly

• the tiny leg bones found in snakes that have no legs

• the front legs of a dog that supports its weight as it walks and runs

• the tentacles of an octopus that aid it in movement and catching prey

Which of the following best describes the tiny legs whales have?

• structures that grow and improve in function as they are used

• structures that function at certain times of the year

• structures that will become adaptations when the environment changes

• structures that have lost all or most of their function over time

What type of evidence did was most likely use to reach his conclusion of species with similar DNA are closely related?

• fossil evidence

• structural evidence

• genetic evidence

• evidence from developmental patterns
