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”] What kinds of traits are used to construct phylogenies? What is the key feature of a trait that may be used to construct a phylogeny?...
