a) The Supergroup Unikonta has heterotrophic members that use cytoplasmic extensions for feeding and movement in moist terrestrial environments. Similar structures are seen in Foraminiferans, members of the Rhizaria, where cytoplasmic extensions are used for feeding and attachment. Assuming that this classification represents the most parsimonious relationship, would you use the cytoplasmic extensions as a shared derived character of these two groups? Why or why not? (2 points) b) Would this be a useful feature in constructing a dichotomous key? Defend your answer (= why you took that position) (2 points)
