"Zenith Species are strong monster individuals that have gone through their own independent changes over the years".

Deviant monsters have also developed their own changes independent from the rest of their species, albeit after surviving multiple hunter attacks.

"Zenith Species have unusually developed parts that they use to their advantage in nature".

How are Stonefist's claw, Drilltusk's tusks, and Crystalbeard's chin any different? I'm not seeing anything to indicate that Zenith Species and Deviants aren't essentially the same thing.
