english: And so therefore, if you look at the same region of a genome in many mammals that have been evolutionarily distant from each other and are also ecologically divergent, you will get a better understanding of what the evolutionary prior of that site is, i.e., if it is important for the mammal to function, for its survival, it will be the same in all of those different lineages, species, taxa.
non_english: Prema tome, ako pogledate u isti region genoma kod mnogih sisara  među kojima postoji razlika u evoluciji kao i u prirodnom okruženju, bolje ćete razumeti kakav je taj region  bio pre evolucije, tj. ako je neophodan  da bi sisar funcionisao i preživeo, biće isti kod svih tih različitih porekla, vrsta, taksona.
