In this episode, Stacy Krueger-Hadfield, Kelle Freel, and Rishi De-Kayne chat with Jeremy Yoder about a pandemic-focused Darwin Day symposium, the phylogenetic conservation of a bioluminescence symbiosis, and the online iteration of a venerable population genetics conference. Links to the things we discuss:

• The UAB Darwin Day event — and online video of the talks
• The phylogenetics of cardinalfishes, which host light-producing, environmentally acquired symbiotic bacteria
• Rishi's PopGroup conference interviews
