(a) Draw ONE consensus (phylogenetic) tree to show the full phylogeny from the Porifera to the Arthropoda & the Chordata (Include ONLY these phyla: Porifera, Cnidaria, Ctenophora, Xenacoelomorpha, Platyhelminthes, Misfits (Chaetognatha), Mollusca, Annelida, Panarthropoda (Phyla: Tardigrada, Onychophora, Arthropoda). Arthropoda subphyla: Crustacea, Hexapoda, Myriapoda, & Chelicerata.).
(b) On your drawing, label the major clades you learned throughout the course that conveniently group phyla at different classification levels (think of synapomorphies and classification vs phylogenetic schemes presented at the beginning of each lecture).
(c) Discuss in detail the major changes in body plan & major organ systems & include any intermediate phyla that occurred as the invertebrates evolved into protostomes (Spiralia & Ecdysozoa) and deuterostomes (the Echinodermata, Hemichordata and the Chordata).
(d) Recent phylogenetic studies have found that CHAETOGNATHA has found its “home” in the phylogenetic tree. In your phylogenetic diagram above, indicate where it is placed now by scratching the original label and branch and drawing a new branch where it belongs to now.
*i have attached a phylogenetic tree with all phyla on it, you can use it the help answer these questions
