  Discuss natural selection and artificial selection. What are the implications of the latter on the process of evolution?

Answer:

                  Natural selection is a gradual, non-random by which biological traits become either more or less common in a population as a function of differentia; reproduction of their bearers, It's a key mechanism to evolution. In natural selection the environment acts as a sieve through which only certain variations can pass. Artificial selection is a process .in which animals and plants with desirable traits are considered by Human breeders and favoured for reproduction. It is an artificial mechanismit is also called selective weeding as it promotes traits that suit human preferences. In contrast to natural selection, here the evolution is intentional or guided.
