Evidence of Evolution

Multiple Choice

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

Multiple Choice

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

• increase in number
  
• become extinct
  

Multiple Choice

Which layer is the youngest

• 1
• 2
• 3
• 4

Multiple Choice

How do fossils provide evidence that evolution has happened on Earth?

• Fossils show how the sizes of certain animals has changed drastically over millions of years
• Fossils show that some species have gone extinct
• Fossils show how life forms present today are different than those from the past
• Different sedimentary rock layers provide evidence for how the environment has changed over time

Multiple Choice

The fossil record help scientists

• better understand the kinds of organisms that lived in the past

• better understand how the environment has changed over time

• better understand how organisms have evolved over time

• all of the above

Multiple Choice

Multiple Choice

Vestigial structures

• structures that perform a similar function but are not similar in origin

• remnants of once-important structures that have slowly lost all or most of their function

• features found in different organisms that share structural similarities but may have very different functions

• preserved remains of an organism

Multiple Choice

What best describes the hind leg bones seen in the whale?
