Answer:
Character displacement & Evolution by natural selection
Explanation:
Character displacement is the name used to illustrate an evolutionary change that happens when two related or similar species inhabit the same environment. Under this type of conditions, natural selection supports a divergence in the characters--morphology, behavior, ecology, or physiology--of the living organisms.
While natural selection refers to the differential survival and reproduction of species in an environment due to differences in phenotype. It is a vital mechanism of evolution, the change in the genetic traits and characteristic of a population over several generations.
