divergent evolution occurs when some species take a different path than of the same species.

convergent evolution happens when the animals that are not the same species look similar as the species living on the area.

different species form because over time things change and they become different. and the theory of evolution says that over time that things are going to change. and when other animals mate with different ones thats how they evolve.

alcohlism is a bad thing that has been done for a long period of time. i think people shouldn't drink and become alcohlists because its going to affect our brain in the long run. alchol gets to our brain and deteriorates it until we are unconscious. and if alcohl is taken too much it could kill us.
