I don't remember exactly what Spot devolved into, but as all mammals have reptilian ancestors, that makes some modicum of sense. But how does Barclay "devolve" into a spider?
Maybe after the Cytherians took him over, some of his DNA was permanently rewritten to resemble theirs and no one noticed it. And maybe the Cytherians were descended from arachnid ancestors, so he devolved into one of them.
Hey, it makes more sense than the actual episode.
