Nels and Vincent review experiments showing that the replacement of a pale moth with a black one during the industrial revolution was caused by a transposable element.
Nels and Vincent speak with Jim Bull about the results of genetic models which suggest that the evolution of inbreeding in response to lethal gene drive might make population control difficult to achieve.
Nels visits Vincent in the MicrobeTV studio in New York and talks about how key genes of the Homo sapiens innate immune response were acquired from Neanderthals.
Mike joins Nels and Vincent to talk about his work on what controls whether pigeons have scaly or feathered feet, and reveals that the hindlimbs of domestic birds with feathery feet are more like wings at the molecular level.
Nels and Vincent continue with an emerging sub-theme of TWiEVO – organisms with wings – as they reveal enhancer shuffling as a mechanism for producing diverse butterfly wing patterns.
Sara and Kartik join Nels and Vincent to talk about how the filovirus receptor NPC1 regulates Ebolavirus susceptibility in bats.
Nitin joins Nels and Vincent to explain how he identified a gene that is responsible for male inviability in hybrids from a cross between two species of fruit flies.
Nels and Vincent discuss the evolution of recombination in the genomes of birds and yeast.
Nels and Vincent talk about how a cellular enzyme contributes to the very high mutation rate of human immunodeficiency virus type 1.
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.
