Evolution Review

What is the term for a feature that allows an organism to survive better in its environment?

• variation

• adaptation

• homologous structure

• vestigial structure

What is the process in which humans breed organisms for certain traits?

• natural selection
• inheritance
• artificial selection
• descent withOUT modification

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 gradual change in species over time is...

• Evolution
• Nucleotide 
• Adaptation
• Natural Selection

What is another name for natural selection?

• survival of the smartest
• survival of the fastest
• survival of the biggest
• survival of the fittest

Survival of the fittest or when favorable adaptations reproduce faster is called what?

• Evolution
• Adaptation
• Natural selection
• Fossilization

Which of the following is an example of a vestigial structure?

• the wings of a red-tailed hawk
• the hind limbs of a house cat
• the fins of sharks
• the tailbone of a human

The ability of an organism to survive and reproduce in its specific environment 

• diversity.
• evolution
• adaptation
•  fitness

__________ characters are similar characteristics that have evolved separately in two unrelated organisms.

• analogous
• homologous
• cladistic
• phylogenic

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.
