Yeah, that's the thing, though. At least Spearow/Fearow and Starly/Staraptor share common traits. Mamepato is very, very clearly based on a pigeon as Wargle is very clearly based on an eagle. The other lines blurred the differences well enough. I just can't picture those two clearly defined species being related to each other, is all.
Errr... that was sort of my second point. That while in Pokemon a pigeon could easily evolve into an eagle and not be unusual or strange, Mamepato (and Hatohpoh) and Wargle are not alike in any way so evolution between the two is pretty improbable.
