Suppose two populations of a single species of lemur are separated for thousands of generations. The environments of the lemurs are slightly different. What will most likely happen to these two populations?
both populations will become new species

what is the definition of artificial selection?
the breeding of plants and animals with desired traits to attempt to produce offspring with these same traits

what is the definition of natural selection?
survival of the fittest; the organisms that have adapted the best are the ones that will survive and reproduce.
