Question

Why does the population of yellow beetles increase overtime?

  1. Natural selection acts against them
  2. Natural selection acts in favor of them
  3. They develop mutations
  4. The green beetles change color

hintHint:

The population of yellow beetles increase overtime because natural selection acts in favor of them

The correct answer is: Natural selection acts in favor of them


    • Natural selection can be described as the adaptation of organisms according to the environment of their habitat.
    • The traits that are most helpful for survival in an environment become more common through the process of Natural selection.
    • The favourable  traits are passed on to the next generation.
    • In this case the crows are fond of green beetles, so yellow bettles have the better chances of survival.
