Buck and Sean join Vincent in New York, while Sylvia is with Nels in Salt Lake City to discuss the first mutant ant ever made: disruption of orco, a gene required for function of odorant receptors, causes defects in social behavior and fitness.

From the Microbial Pathogenesis Retreat of the University of Utah School of Medicine, held at the Utah Museum of Natural History, Nels and Vincent speak with faculty members about their work on bacteria, fungi, viruses, and mirror-image biochemistry.

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.

Josh joins Nels and Vincent to talk about his research on the evolution and conservation of aquatic tropical biodiversity, and the historical ecology of 19th century American Whalers.

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.

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.

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.
