Cladistics is the search for your own classification

The approach in biological systematics called "cladistics" is the search for your own classification, and since classification is paradoxically contradictory (see Russell's paradox), it is infinite (ie, an infinite recursion) per definition. Every specific solution contains paradoxical contradictions (ie, single entities that possess mutually exclusive properties) per definition.

Don't let cladists fool you into this eternal merry-go-round.
