In a certain species of butterfly, there are three possible color variation: dark brown, mottled, and yellow. Birds prey on these butterflies. The individuals with dark brown coloration can easily blend in with the bark of trees. The individuals with mottled coloration can easily blend in with leaf litter on the ground. The individuals will yellow coloration are not able to blend in with any natural surface so they are easily seen and eaten by the birds. What type of selection is this? O Diversifying selection. O Stabilizing selection O Directional selection.

Genetic Evolution

Sexual reproduction produces distinct population variations. Heredity determines the traits and qualities to be passed down to the progeny. Over time, this variation within-species is also affected by the process of human evolution. The study of how genetic variation leads to evolutionary changes is known as genetic evolution. If a trait helps an organism to survive and reproduce, it is more likely to be passed down the generations. It is rare that such traits result in a completely distinct set of traits in descendants than the ancestral population; this can result in the emergence of a new species.
