The objectives of this course are to know and understand methods of phylogenetic reconstructions, and to be able to use trees in the current genomic era
Beside discussing what is a phylogenetic tree and how to interpret it, we will introduce the main reconstruction methods available. This will include a thorough description of
- optimization critera and models of evolution
- finding the optimal tree
- Bayesian methods and MCMC
- how to be sure you have the right tree?
Then we will discuss several aspects that uses phylogenetic trees as tool to understand gene and organisms evolution. This includes
- estimating gene trees and species trees
- detecting positive selection on coding genes

- Maximum Likelihood and Bayesian (pdf) -- phyml output
- Testing positive selection (pdf) -- paml output
- Estimating species trees (pdf) -- *BEAST output, summary of the biological context
