Nels and Vincent continue their discussion of SARS-CoV-2 from an evolutionary viewpoint, focusing on what the genome sequences tell us about the virus.
Nels and Vincent dive deep into evolution and consider how new proteins emerged billions of years ago, when there were no other proteins to serve as starting material.
Nels and Vincent discuss signatures of sex chromosome evolution revealed by assembly of a young vertebrate Y chromosome from 3-spined stickleback fish.
Rich joins Nels and Vincent for a debriefing on the 4th Ringberg Symposium on Giant Virus Biology in Tegernsee, Germany.
Nels and Vincent reveal a new choanoflagellate that forms multicellular cup shaped colonies that respond to light to alternate between feeding and swimming behavior.
Nels and Vincent trace the origins of Saccharomyces cerevisiae strains used to make beer, and find that ales and lagers are made with yeasts that were derived from those used to make European grape wine and Asian rice wine.
Nels and Vincent analyze the genomes of canine transmissible tumors to provide insight into the worldwide spread of the disease from its origin in a single dog 4000-8500 years ago, and its diversity, mutation, and evolution.
Nels and Vincent review the contribution of multiple Denisovan lineages to the modern Papuan genome.
Nels and Vincent explore the evolution of new protein-coding genes de novo from nocoding DNA sequences, using the antifreeze protein of northern codfish as a model.
Nels and Vincent move back to reproductive isolation – this time, pre-zygotic, in the charismatic orchid bee where the males make chemically distinct perfumes to attract mates of the same species.
