Molecular Evolution - #27615

Course Programme - Spring 2013

Teacher: Anders Gorm Pedersen

The course starts Wednesday, February 6, 2013, and runs each Wednesday from 13:00 to 17:00 (except for April 17th which is easter holiday). Lectures and exercises will take place at the Center for Biological Sequence Analysis at the Technical University of Denmark, building 208, auditorium 062 (in the basement below CBS). Participation in the weekly lectures/exercises is required (since it counts as part of the exam).

Classes will be a mixture of lectures, problem solving (bring a pocket calculator), computer exercises (bring your laptop - requires wireless network and some software), and micro projects done in groups of two.

Textbook:   Inferring Phylogenies by Joseph Felsenstein, Sinauer Associates, Inc., 2003. The book can be bought at Polyteknisk Boghandel, DTU. It is a good idea to check the online list of typos and comments when reading.

Please note: the program may change slightly along the way. The required readings for a class can be trusted from one week prior to the class. The exact content of powerpoint slides and handouts may change up to the last minute!

Recordings: To view recorded lectures you will need the (free) Quicktime Player (Mac or Windows).
