Here is an unusual collection of slides. The first, which is upside down, is the phylogeny of fish. Next comes an article about invasive lampreys in the Great Lakes area. The third slide shows the life cycle of sea lampreys. A reptilian phylogeny appears on the fourth slide. Next you see birds in a phylogenetic tree followed by that of the mammals. To make this a cohesive presentation for your evolution curriculum, leave out the lamprey information.
