|
Insects see the background they want to blend into, and then actively change their genotype to match the background.
|
|
|
Insects rub against the leaves, bark, or dirt that they live on, so that the pigments from these substances are transferred to their bodies. Their offspring inherit this coloration and blend in more effectively.
|
|
|
Mutations occur frequently, so that each offspring insect is a completely different color. Based on their coloration, the insects seek a habitat they can blend into.
|
|
|
Mutations affecting coloration occur randomly in insects. Insects with mutations that help them to blend in are more likely to survive than others, and gradually these helpful mutations accumulate in the population.

Detailed explanation-1: -Natural selection is a mechanism of evolution. Organisms that are more adapted to their environment are more likely to survive and pass on the genes that aided their success. This process causes species to change and diverge over time.
Detailed explanation-2: -According to Charles Darwin’s theory of evolution by natural selection, organisms that possess heritable traits that enable them to better adapt to their environment compared with other members of their species will be more likely to survive, reproduce, and pass more of their genes on to the next generation.
Detailed explanation-3: -Insects rub against the leaves, bark, or dirt that they live on, so that the pigments from these substances are transferred to their bodies. Their offspring inherit this coloration and blend in more effectively. Mutations occur frequently, so that each offspring insect is a completely different color.
Detailed explanation-4: -Because the primary goal of all organisms is to reproduce, or to pass their DNA onto offspring, fitness is defined as the ability to reproduce and create viable offspring.
