The theory of evolution suggests that

• Closely related species will show similarities

• All of the above

Natural selection is the process by which

• The age of selected fossils is calculated

• Acquired traits are passed on from one generation to the next

• all of the above

The process by which a species becomes better suited to it's environment is known as

• Adaptation

• Accommodation

• Variation

• Selection
