 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/  \  -----------------...
