10.a. Describe the differences between the terms in each of the following pairs. (i) Coelomate versus acoelomate body plan (ii) Protostome versus deuterostome development (ii)Radial versus bilateral symmetry (b) Explain how each of these pair of features was important in constructing the phylogenetic tree shown below. Use specific examples from the tree in your discussion. 24-10 20 11.1 11.The two phylogenetic trees shown on the next page represent the relationship of whales to six other mammals. All of the organisms shown have a pulley-shaped astragalus bone in the ankle except for the whale. a. For each tree, describe a monophyletic group, the closest relative to the whale, and the point at which the pulley astragalus bone was lost or gained. b. Based on the principle of parsimony (the simplest explanation is the best) and the genomic information in the table shown, identify which tree is the best representation of the evolutionary relationship of these animals, and justify your answer.
