Building a Phylogenetic Tree of the Human and Ape Superfamily Using DNA-DNA Hybridization Data

The study describes the process of DNA-DNA hybridization and the history of its use by Sibley and Alquist in simple, straightforward, and interesting language that students easily understand to create their own phylogenetic tree of the hominoid superfamily. They calibrate the DNA clock and use it to estimate the divergence dates of the various branches on the tree.
