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.
Sarah Tishkoff joins Nels and Vincent to explain work from her laboratory on the genetic basis of skin pigmentation in Africans.
Taking a cue from the recent frigid weather, Nels and Vincent explore how modifications of a neuronal cold-sensing channel regulate diminished cold sensitivity in hibernating mammals.
