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.
Nels and Vincent discuss how the loss of an enzyme in marine mammals millions of years ago now makes them at risk for neurotoxicity caused by human-made organophosphorous pesticides.
Matt joins Nels and Vincent to discuss the neutral theory of evolution and its rejection in light of genome-scale data.
Nels and Vincent reveal how a motor protein in corn causes preferential transmission of chromosomes to egg cells, leading to non-Mendelian inheritance
Nels and Vincent discuss the evolution of blood feeding to nonbiting in a mosquito, and evolution of bacterial virulence in the house finch caused by incomplete host immunity.
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.
Nels and Vincent explore the role of TSR proteins during colonization of cnidarians by dinoflagellates.
