This course is a companion course to BIOL 2063. It provides training in generating and interpreting phylogenetic trees; provides exposure to molecular and morphological data (in extant and extinct organisms) to identify organisms and test hypotheses about their relationships; provides exposure to a variety of different organisms to explore key innovations that have led to changes in biological diversity; and teaches techniques to study organisms and biological diversity (computer software, binomial keys, microscopy, dissection, comparative observation, and sampling and collecting).
