Cladograms of Groups of Living Orga

Cladograms of Groups of Living Organisms

by G. F. Guala
Teaching the major groups of life and their inherent relationships to undergraduates is difficult because, even though it has been 25 years since many of the major groups and their relationships were discovered, college textbooks (in general) still tend to cling to outdated information and concepts with respect to the evolution of life and its products. Thus, I have constructed these illustrations as a part of an integrated program that I developed for teaching basic biology at the undergraduate level. I have used these illustrations in several semesters of teaching Introductory Biology at the University of Florida and some have been used by my colleagues at other universities. The illustrations on each of the cladograms are from many sources (cited at the bottom) and I must stress that these citations should be kept with them. This also means that it is probably unrealistic to use these legally in any profit making enterprise. I encourage their use in all teaching otherwise.
