Construct a phylogenetic tree of the following organisms: turkey, pine tree, dog, clam, daisy, andfern. Use the following "evolutionary novelties" to defineeach group: backbone, shell, photosynthetic (produces ownfood), flowers, cones, seeds, heterotrophic (must acquire food),feathers, eukaryotic, and hair. Indicate these novelties onthe tree.Based on this phylogenetic tree, is the group including pinetree, daisy, and fern monophyletic? Justify your answer --that is, explain why the group is monophyletic or not. Inyour answer, be sure to demonstrate that you know what"monophyletic" means.
