State

This procedure classifies an unfamiliar protist into its supergroup by matching its described structural features against each supergroup's defining criterion in turn.

Watch for

Matching one structural feature alone is not sufficient— this procedure works only by ruling supergroups out systematically, since a single trait can appear convergently across more than one group.
