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?
The beetle population will be half green and half red.
All the beetles will be wiped out because of predator attacks.
Most of the beetles will be green.
Most of the beetles will be red.

Answer 1

Most Most of the survived beetles will be green

Answer 2

Answer: Most of the beetles will be green

Explanation:

Natural selection is a phenomena of differential survival and reproduction in which the organisms which exhibit better phenotypic traits will survive and reproduce.

The given situation is an example of natural selection. The green color of the beetles will allow them to remain undetected by the predators as their color is identical to the color of the grass in grassland. Therefore, these beetles will camouflage the predators. Thus it can be said that green color is a beneficial phenotypic trait. These green beetles will survive and reproduce. Hence, the most likely change that will happen over time is that the most of the beetles will be green.
