Taxonomic changes aren't made just for fun, you know! The point of
taxonomy is to try to encapsulate the evolutionary process, and as our
knowledge of what is most closely related to what increases, the
nomenclature changes to reflect that.

The taxonomists and the geneticists I knew used to be at loggerheads for a
fair fraction of the time.

They're both trying to come to the same result. But they're both trying
to discover a historical process on the basis of a snap shot now, so
it's not surprising that they don't necessarily come to the same
conclusion.
