Draw the phylogenetic tree that shows that understanding of the evolutionary relationships of all invertebrates among the major phyla of metazoans. What are the major clades shown on the tree? Why are the phyla grouped together in the specific clades that you have drawn? What are the synapomorphies that define each of the clades and the different phyla within them? What sources of evidence were used to reconstruct the phylogeny that you have drawn? Are certain sources of evidence more...
