Question

Red and green beetles from a forest migrate to grasslands. In the new environment, green beetles are able to protect themselves better from predators through camouflage. Which change in the population will most likely happen over time?

Answer 1

Red beetles will more likely to decrease over time, meanwhile the green beetles may increase.

Answer 2

The correct answer is - green beetles will increase and red beetles would decrease due to natural selection.

Explanation:

Natural selection is a process that suggests that the population or species that shows better phenotypic traits will survive and reproduce more than the species that lack the ability to adapt to the change in the environment.

The presented case is also an example of natural selection. The green beetles are able to adapt to the change in the environment. That allows them to hide from the predators and be protected than the red beetles that do not change according to the atmosphere and will be easily found by the predators and will decrease.

Thus, the correct answer is - green beetles will increase and red beetles would decrease due to natural selection.
