However, the idea of a new species is entirely based on boundaries instituted by the scientific community. Linnaean Taxonomy is largely qualitative. It is the collaboration of scientists studying these organisms which determines classification. Now, there are guidelines, but the classification of species has always been a qualitative human endeavor.
This points us in the direction of explaining why creationists ARE ALWAYS wrong.
It's about perspective.
They think that everything in the world has little labels and that everything fits into specific categories.
They think that there is a "seagull" box and that ALL seagulls are in it. They think that that box was created by a Jew Wizard and that the sides are magic.
This is also why they hate homosexuals and transgendered people. They don't fit nicely into their box.
This is a fundamental misunderstanding of how language and thought work.
I would not be surprised in the least to discover that Creationists were overwhelmingly against reclassifying Pluto.
