To answer this we need to remember how proteins are structured, the primary structure is just the polypeptide chain, secondary there is a certain folding level alpha-helix and folded beta-sheet, then is the tertiary structure that comes from a single polypeptide chain and is formed by secondary structures, finally, there is the quaternary structure where several polypeptide chains are involved as well as tertiary structures are folded together. Therefore taking this into consideration we can say that the correct answer is option two.

The members of the initial species, start to exhibit new behaviors, new ways of feeding, change in coloration, all in order to be better suited for a specific ecological niche.
