Fresh-water fish (and other life-forms, also), of similar and identical 
species even, live in widely scattered bodies of water (lakes and rivers)--
so widely scattered, in fact, that it is hard to imagine these bodies were 
ever connected in the past by fresh water. How did these fish get from 
their supposedly unique places of origin to all the places where they live 
today?
