Teaching language

English

Objectives

The course aims to give students an understanding of the importance of phylogenetics for systematics, comparative biology, biomedical issues and conservation planning. Widely used methodologies are discussed and compared, along with the relative philosophies behind each method. 

Learning outcomes and competences

The aim is that by the end of the course students can take data from the web and analyse it in a phylogenetic framework, while appreciating the differences between alternative methods.

Program

Introduction to phylogenetics. Why is it so important?

A brief history. From Darwin and the first "trees", through debates of
cladistics vs phenetics, to parsimony vs likelihood and to the present
situation.
 
Methodologies. Maximum Parsimony, Distance methods (minimum evolution,
neighbor-joining and UPGMA), Maximum Likilhood and Bayesian Inferences.
The pros and cons of different methods.
 
Consensus methods. How to combine sources of information.
 
Support methods. Bootstrapping, Bayesian Posterior Probabilities, Decay
Index. What do they mean and how to compare them.
 
Philosophy. If Popper was right, are we barking up the wrong tree?
 
An assessment of the interplay between population genetics and
phylogenetics. Why use networks instead of trees? Comparing the methodologies above and below the species level.
