We will follow up on Emily Lemmon's visit by discussing her methods paper on anchored enrichment. 
Continuing on the phylogenomic theme, Louise Lewis and Karolina Fučíková will lead a discussion on the following shakeup in the green plant tree:

Since cichlids came up last week, it may be fun to read a cichlid RAD-seq paper:
