An assignment constructing phylogenetic trees using shared, derived morphological traits and molecular differences among 18 primate species and two outlier species has been developed. Skull and body images and a table of morphological characteristics were used to fill in a pre-fabricated tree. Molecular differences of the cytochrome b gene obtained from the NCBI website was used to generate a tree using the Phylogeny.fr website for the same 20 species. Several followup questions were provided upon completion of the assignment.
