(S8.2) A species of fly follows the sounds that male crickets make with their wings. The flies deposit their larvae in the crickets' bodies. As the larvae develop and emerge from the crickets' bodies, the crickets die.

 

Researchers have discovered a genetic mutation in some crickets that changes their wing structure and makes them silent, causing the flies to ignore them. The crickets with silent wings are found among crickets with normal wings when it is time to mate.

 

According to evolution by natural selection, which of the following will most likely occur in the cricket population, based an the selection pressure from the flies?

A) The population of male crickets with silent wings will increase in number.

B) The frequency of the silent wing mutation will stay the same.

C) Male crickets with normal wings will learn to make new sounds.

D) A new mutation will create spikes on the crickets' wings to keep the flies away.
