Sarah Tishkoff joins Nels and Vincent to explain work from her laboratory on the genetic basis of skin pigmentation in Africans.
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 reveal how the protein DHX9 suppresses RNA processing defects caused by invasion of the Alu retroelement into the human genome.
Corrie Moreau joins Nels and Vincent to talk about her comparative analysis of the genomes of mutualist ants that nest in plants, and non-symbiotic species.
Nels and Vincent discuss the evolution of recombination in the genomes of birds and yeast.
Nels and Vincent launch a new podcast on evolution, and start by discussing how the field has changed through recent mergers of evolutionary and experimental biology in the post-genome era.
