Evidence of Evolution

What does Darwin's theory of evolution suggest?

• species change over time

• different species can interbreed

• extinct species are not related to living species

• animals that look alike are most closely related

Which of these answers correctly pairs a scientific discovery with the type of evidence for evolution that it represents

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
