If you are looking for laboratory exercises to use in your classes you are welcome to try these. Some of these exercises could be adapted for high school as well.
Some mention is made of where the lab came from, even if it is modified.
Classification and Evolution Caminalcules are imaginary animals invented by the evolutionary biologist Joseph Camin. They make ideal organisms for introducing students to the related topics of taxonomic classification and evolution. This illustrates how modern classification schemes attempt to reflect evolutionary history. In the process of doing this exercise the students are also introduced to concepts such as convergent evolution and vestigial structures. The pictures of the Caminalcules are copyrighted by the journal Systematic Biology and Robert R. Sokal.
