Natural Selection

Why do peppered moths tend to be the same color as the trees on which they live?

• The coloring goes along with tasting like the tree. 
• It keeps the moth the same temperature as the tree. 
• It makes the moths faster than the birds
• It makes the moths harder to see.

Which of these is an example of natural selection?

• The largest animal in a population will have more opportunities for reproduction.
• Several species of organisms work together so that they all succeed.
• One species takes all the resources in an environment leaving none for others.
• Organism that are best suited to an environment tend to survive and reproduce more often.

Which of the following explains adaptation.

• An individual organism changes to meet its needs in the environment. These changes pass down to their offspring.
• The species as a whole changes their characteristics.
• Beneficial traits allow organism to survive and pass on those traits
• New characteristics arise in a species as needed.  If these traits are helpful, they are passed down.

Some organisms change to resemble their surroundings even when that environment changes.  They most likely do this to

• be easier to see
• be harder to see
• attract a mate
• to adapt their diet

Evolution works by 

• individuals changing to suit their environment
• Individuals learned new traits and pass them on
• sudden change in the environment cause a species change 
• small changes pass down through many generations

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.
