Which of the following is true regarding Darwin's theory of evolution?

Which of the following most likely caused this change?

• The mutation was contagious.

• Other newts learned to copy the strategies of the mutated newt.

• Newts with the mutation are better able to survive and reproduce than newts without the mutation.

• The newt passed on its mutated gene to other adult newts.
