Divergence time analyses have become increasingly popular over the past several decades, partly due to the proliferation of molecular data, but also because of the development of methods that do not assume a strict molecular clock. In this review, I provide a brief background to the topic, then highlight several methods for relaxing the assumptions of a strict molecular clock. I discuss the pros and cons of many of these methods. Finally, I discuss the various techniques for incorporating fossils in molecular studies to estimate absolute ages of clades.
