12 Coronavirus phylogenetics

In this lab, we’ll use Nextstrain to explore the evolution of SARS-CoV-2 and then build our own coronavirus phylogenies within R.

12.0.0.1 Learning objectives

After completing this chapter, you’ll be able to:

1. Interpret viral phylogenies and associated data on Nextstrain.
2. Explain how incomplete sampling affects phylogenies.
3. Describe how phylogenetic trees are built through neighbor joining.
