Sometimes I like to think biology and taxonomy as a field is, if anything, even more complicated in the pokemon universe than it is in ours? Like it’d be really funny if the seemingly straightforward, reliable, and intuitive systems that are explained to us in the game is just the simple version given to young people who tend to be just starting out in their relationships with pokemon while across the country you have like. Professor Sycamore giving speeches about how much oversight was required to formally accept Fairy as a valid typing and getting derailed by a pundit talking about the Flying type and he’s like “Don’t talk to me about the flying type if you so much as look at the Flying type you’ll get into about eight taxonomical arguments that have been going on longer than you’ve been alive”
next door you have people arguing for the billionth time whether or not Cleffa should be recognized as a True pre-evolution of Clefairy or if the differences in its anatomy aren’t significant enough to classify and there’s at least one school of thought that Evolution doesn’t exist and the only real pokemon are final evolutions, so neither pikachu nor pichu are their own creatures they’re just immature and/or neotenous raichu.
Somewhere else in the world you have a paleontology conference discussing the latest fossils found of the ancient pokemon basculegion and reconstruction implications only for a time traveler to slam the rear doors open like “I SAW GOD, WAS THROWN BACK IN TIME, AND BASCULEGION DID NOT LOOK LIKE THAT,”
