>>56743948Mustelidae is a weird group, they seem to be grouped based on how they look rather than sharing an ancestor.
skunks were part of the group not to long ago they were moved to their own group. (though they are still in the Musteloidea Order).
Phylogeny is already had to discuss but adding Pokemon into the thing makes it even more confusing with how often Pokemon change species when evolving along and hard hard is can be to tell what species an individual Pokémon is. Cyndaquil;s goes from shrew/echidna, to crested porcupine/stoat/, to badger/wolverine and according to zodiacfags all are ostensibly also rats.
