Base your answer(s) to the following question(s) on the diagram below that shows variations in the beaks of finches in the Galapagos Islands and on your knowledge of biology. The diversity of species seen on the Galapagos Islands is mostly due to

• gene manipulation by scientists 

• gene changes resulting from mitotic cell division 

• natural selection 

• selective breeding

According to the theory of natural selection, why are some individuals more likely than others to survive and reproduce? 

• Some individuals pass on to their offspring new characteristics they have acquired during their lifetimes. 

• Some individuals are better adapted to exist in their environment than others are. 

• Some individuals do not pass on to their offspring new characteristics they have acquired during their lifetimes. 

• Some individuals tend to produce fewer offspring than others in the same environment.

In members of a bird species living on a remote island, the greatest number of beak variations in the population would most likely be found when 

• there is a high level of competition for limited resources 

• homeostasis is limited by a severe climate 

• they have a large and varied food supply 

• they are prey for a large number of predators

How did different beak sizes first arise?

• They arose because of their need to be able to eat different food.

• The arose by chance (random mutation).

• The environment made the change happen.

• The finches beaks changed a little at a time each generation.
