Answer:

The behavioral change for the avoidance of guppies from predators. This natural selection leads to the structural change in male guppies.

Explanation:

  • The large bright spots on the male guppies are used to attract the females for the mating.
  • But a predator which detect guppies by sight can easily sense them and hunt them.
  • For their survival, the trait of large, bright spots on the male guppies was changed.
  • This change leads to their less chances to be hunted by the predators.
  • Hence this is a behavioral change for their survival.
