1.) Describe one trait that all the species have in common (an ancestral trait).

 2.) Describe two traits (including the phenotype that some of the species share but other objects do not (shared derived traits).

3.) Describe one trait that is particularly unusual, perhaps found in only one species (a unique derived trait).
