Question

What is the explanation for the survival of green beetles in red beetles population, where crows are predators? How is it possible?

Answer 1

Natural selection:

1. It is the process by which organisms evolve to adapt to their surroundings.
2. According to natural selection; organisms with more suitable traits survive, whereas others perish.
3. The suitable traits enable the easier adaptation of the organisms to an environmental change.
4. The theory of natural selection was proposed by Darwin.

Green beetle over red beetle:

1. Predators cannot easily spot the green beetles due to the resemblance of their color with the leaves.
2. It is easier to spot the red beetles as they stand out for their color.
3. Natural selection in the beetle population is driven by the predator (crows) that prey on the red beetles.
4. The green beetle population rises as they survive predation and reproduce.
5. The natural selection of the green beetles over the red beetles causes evolution in the beetle population.
6. The survival advantage of the green beetles over the red beetles is due to their color.
