Answer:
organisms acclimate over time is by adapting to their habitats and their ecosystem. If i were to make a population of wolves into a chihuahua i would make sure that the habitat is smaller and also the amount of resources available should be less than what they are used to. This should cause them to become smaller to help preserve energy.Once they breed and a favorable genetic is present, that wolf is used to breed with another wolf that has a genetic mutation that would make it smaller and more domesticated. By taking genetic mutations that are a result from these changes you can get a wolf to be more domesticated and become smaller. like a chihuahua
