EVOLUTION LINK Examine the cladogram in Figure 30-6a. Based on the discussion in this chapter, what were some of the types of data that biologists used to determine these phylogenetic relationships?
You want to construct a cladogram for all species of ducks, which are Birds (Aves). Explain why "presence of feathers" would not be a useful character trait to use to reconstruct their evolutionary relationships.
