Wasp Genetics (VIDEO) University of Rochester This video is under embargo. Please login to access this video. Caption In a study published in Current Biology on June 22, the lab of Professor John Werren at the University of Rochester describes how four closely related species of parasitic wasps change their venoms rapidly in order to adapt to new hosts, and proposes that co-option of single copy genes may be a common but relatively understudied mechanism of evolution for new gene functions, particularly under conditions of rapid evolutionary change.
