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.
