1. Why are clades “supported” by one or more synapomorphy? We expect the synapomorphy to be present in all the members of the clade defined by the trait – but the character might be highly modified, or present only a brief developmental stage. [Sometimes the trait is lost altogether, a situation we call being “secondarily lost”]

4. Explain the statement “all clades are subsets of larger clades”. What is the largest clade?
