• In the second case of Beetles, all the Beetles were red and they hid uder the bushes for their survival.
• There developed a slight variation in the beetle coloured as it changed its colour to Blue.
• The blue Beetles reproduced and gave birth to certain number of Beetles.
• Imagine, an elephant stamped the bushes. Since the red beetles was in large number, all the red beetles were dead but the blue Beetles survived.
• Since there is no red beetles, now no more red beetles are going to reproduce unless there is another variation.

• This proves that natural selection can bring in a variation.
• Same is in the case of the moths.
