Nels and Vincent answer listener questions and discuss a newly discovered virus of amoeba with a nearly complete ORFan genome: none of the proteins encoded in the viral genome look like any other proteins.
Jessie, Allie and Tyler join Nels and Vincent to describe their work on deep mutational scanning of the SARS-CoV-2 receptor binding domain.
Matt joins Nels and Vincent to discuss the neutral theory of evolution and its rejection in light of genome-scale data.
Nels and Vincent discuss a genomic analysis of the passenger pigeon, which shows that species with large and stable populations may be at risk of extinction after a sudden environmental change.
