(Note: Volume needs to be turned up)

Vanderbilt University undergraduate and Littlejohn Summer Research Scholar Ashley Saulsberry discusses her thesis work on the origin of species. In the lecture, she describes a newly evolved reproductive barrier that kills hybrids between the closely related wasp species of N. vitripennis and N. longicornis. The hybrid mortality evolved in the Bordenstein lab circa 2008, and Ashley is deploying classical genetics to unravel the genetic basis of this new hybrid incompatibility.
