Change over time...

• Evolution
• Nucleotide 

To adjust to a changing environment

• Mutation
• Adapt

Which of the following is NOT an example of natural selection? 

• People selectively breeding hamsters.
• Insect populations developing resistance to certain pesticides.
• Bacteria becoming resistant to antibiotics.
• Male birds of certain species developing colorful feathers to attract female mates.

Which term refers to the process by which individuals that are better suited to the environment survive and reproduce therefore passing down their genes to their offspring? 

• Evolution 
• Variation 
• Adaptation
• Natural Selection 

When an organism completely dies out, it is called.....

• Adaption
• Extinction
• Fossilization
• Mutation

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

The fossil record provides evidence that 

• Fossils cannot be dated.
• All species were formed during Earth’s formation and have changed little since then.
• The fossilized species have no connection to today’s species.
• Older species gave rise to more-recent species.

Structures with no function that are remnants of an organism’s evolutionary past are

• Not visible organisms.
• Vestigial
• Young in origin
• Useful to the organism

How would you describe this evolution?

• Homologous structure
• Analogous structure
• Structural adaption
• Functional adaption

A giraffe has a long neck in order to better reach leaves to eat. This is an example of _____.

• an adaptation

• environment
