Week 4 materials

No class

During this time we’d like you to watch the following 4 video lectures by Paul Lewis and answer a set of questions we have prepared. Paul Lewis has made numerous important contributions to the field of statistical phylogenetics, as well as producing excellent tools and materials for learning about phylogenetic theory. The videos we’ll use were developed as part of the phyloseminar series.

The videos will take about 3.5 hours to watch. Read the questions before you watch each video and write down your answers in the linked google form – we’ll go over these in week 5. Remember the goal is not to understand everything! Also make note of any questions you have after watching these and we’ll try to answer them.

videos topics questions forms
Part 1 trees and likelihood Questions 1 Form 1
Part 2 trees, likelihood and rate heterogeneity Questions 2 Form 2
Part 3a Intro to Bayesian phylogenetics Questions 3 Form 3
Part 3b Intro to Bayesian phylogenetics Questions 4 Form 4
