MontanaPBS will broadcast an episode of the popular “NOVA” science program that explores the research and discoveries of University of Montana biology Professor Doug Emlen at 8 p.m. Wednesday, Nov. 22.
The episode, “Extreme Animal Weapons,” is based on an hourlong documentary starring Emlen that originally aired on the BBC in April. Both episodes were inspired by Emlen’s 2014 book “Animal Weapons: The Evolution of Battle.”

In the documentary, Emlen takes “NOVA” viewers to various locations in Montana and Washington, including a ranch with elk overlooking Flathead Lake and a building crammed with 17,000 shed antlers called Jim’s Horn House in Three Forks.
The UM researcher has spent 30 years investigating how weapon-bearing species developed extreme ways to gouge and gore one another using their natural weapons. The episode investigates the riddle of outsize weaponry and outlines Emlen’s new theory about what triggers an animal arms race.
