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

• adaptation
• variation
• homologous structure
• vestigial structure

• analogous structures
• homologous structures
• vestigial structures
• none of the above

Why are advantageous traits more likely to be passed onto offspring?

• Because they are more likely to survive and reproduce.
• Because they come from dominant alleles.
• Because they come from recessive alleles.
• Because the trait is an acquired phenotype.

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

• Evolution
• Adaptation
• Natural selection
• Fossilization

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

• increase in number
  
• become extinct
  

An example of a vestigial structure_______.

• a cat tail

• eyes of cave animals

• your brain

• a rose stem.

What is the most correct definition of evolution?

• Change over time. 
• Animals changing over time. 
• Organisms changing over time.
• Species changing over time. 

When an organism blends into its environment

• natural selection

• camouflage

• embryology

• gradualism
