Reverend Thomas Bayes had no idea that his "...essay towards solving a problem in the doctrine of chances" would influence so many areas of scientific research. For one thing, his paper was not published until after his death! The simple equation now known as Bayes' Rule became the foundation upon which the field of Bayesian statistics is based.

I will talk about how Bayesian statistics is used in the field of phylogenetics, which seeks to understand relatedness among species in much the same way that a family tree shows relatedness among individuals in a population. We will discuss Bayes' Rule and its four components and how the computer simulation method known as Markov chain Monte Carlo (MCMC) is used to sample plausible phylogenies given DNA sequence data from several species.

Note: Free refreshments. The talk starts at 5:40.
