Humans breed dogs for certain traits. What is this practice called?

• variation

• adaptation

• natural selection

• artificial selection

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

The study of the early stages of development that is one evidence of evolution is:

• Comparative Anatomy

• Embryology

• Fossil Record

• DNA comparisons

What is a fossil

• a rock or mineral

• a living organism

• a DNA specimen

• the preserved remains of a once living organism

all are examples of evidence of evolution EXCEPT

• Comparative anatomy

• fossil record

• Family inheritance over 3 generations

• Embryology and development

Which two species are more closely related

• A & D

• C & K

• B & E

• J & K

Which statement best describes the process of evolution?

• Populations can survive in different locations on earth

• Environmental conditions limit the number of species on Earth

• Populations grow when resources are abundant

• The traits of a species can change over time

Which of the items is most likely to be preserved as a fossil?

• A flower

• Hair or Fur

• A tooth

• Blood
