Insectivora is a taxonomic grouping that was used to describe insect-eating mammals like armadillos, hedgehogs, moles, and anteaters. The taxonomy of these animals has beea revised in recent years, and Insectivora is no longer widely accepted because this group of organisms lacks one common ancestor and is instead descended from several ancestors. Which term best describes Insectivora? A. Polyphyletic B. Monophyletic C. Haplophyletic D. Paraphyletic

4) Pretend it's a year later, and you have collected more data to make a more detailed phylogeny. You notice that some of these species of birds are sexually dimorphic (males have significantly different plumage than females, generally much brighter!). You also notice that in some of these species both parents feed the offspring, while in others only the female feeds the offspring. You imagine that having bright males near the nest may tend to attract predators to the young. You want to distinguish between two hypotheses to explain the patterns you see: 1) Males not feeding the young is an adaptation to dimorphism 2) If males don’t feed the young in a species, it will allow them to become brightly colored To begin to address this question, map the characters changes in dimorphism and males feeding the young onto each of the trees on the previous page.
