Phylogenetic analysis of the bony fishes: Morphological and mtDNA sequence comparisons part of Teaching Genomics at Small Colleges:Genomics Instructional Units Minicollection
This three-four week laboratory/lecture module is designed to teach students basic concepts, quandaries, and methods of phylogenetics using interdisciplinary techniques within an inquiry-based curriculum. The overarching question the students are challenged with is, what are the phylogenetic relationships among major groups of bony fishes, a group whose evolutionary relationships remain unresolved. Students generate both molecular and morphological datasets on a group of fishes (whole) that were purchased from a local fish market that span many orders of fish within the Actinopterygii (the main group of fishes), but also representat other closely related groups. We also happened to have a frozen gar, bowfin, and eel that were really good outgroups. With the collected data, in addition to previously published molecular sequences obtained from Genbank, students generate phylogenetic hypotheses and are challenged to reconcile differences in the hypotheses resulting from the different datasets.
