This is a good link for evolutionary terms: https://www.ck12.org/book/CK-12-Biology-Concepts/section/11.2/ If you have: annelids, cheliceriforma, hexapoda, and crustacea Phylums are : annelids and arthropods (cheliceriforma, hexapoda, crustacea) -could talk about segmentation, exoskeleton, moulting, last common ancestor, chilicerae, biramous appendages. terrestial and aquatic, number of legs http://evolution.berkeley.edu/evolibrary/article//arthropods_02 https://en.wikipedia.org/wiki/Arthropod#Evolutionary_family_tree go to "evolutionary family tree" and "classification" ---------------------------------------------------------- If you have: Porifera, Cnidaria, Platyhelminthes, Nematoda All four are their own phylums -could talk about multicellularity, symmetry, tissues, body cavity, acoelomate, coelomate, germ layers Use evolutionary tree - https://www.ck12.org/book/CK-12-Biology-Concepts/section/11.2/ \ --------------------------
