>>51549132Alolan "Sand"slash fits pretty well with how rules of binominal nomenclature works in real life, which say that the first published name for a species is the valid one, no matter what that is. For example, in common parlance "quagga" refers only to a now extinct variety of zebra without defined stripes, but genetic analysis has proven it is the same species as the plains zebra which has been reclassified as Equus quagga since the former was scientifically described first, even if no one calls normal zebras quaggas in common parlance.
Alolan Sandslash is a Sandslash that has migrated to snowy environments and had not enough time to diverge in a new species, so it keeps the old name. Perrserker is a Persian that has diverged more so it gets a new name, despite still evolving from Meowth. Wiglett is just a unrelated Pokémon that happens to resemble Diglett enough to fool the first researchers.
It disturbs your OCD because you don't know how taxonomy works in real life.
