Douglas J Emlen

Douglas Emlen is an evolutionary biologist and Professor of Biology at the University of Montana. He has received the Presidential Early Career Award for Scientists and Engineers from the Office of Science and Technology Policy at the White House, multiple research awards from the National Science Foundation, and the E. O. Wilson Naturalist Award from the American Society of Naturalists. His research provides insights into the development and evolution of exaggerated male weaponry, such as the horns found in scarab beetles. He combines approaches from behavioral ecology, genetics, phylogenetics, and developmental biology to understand how evolution has shaped these bizarre structures. His current projects include an examination of how altered expression of appendage patterning genes contributes to species differences in the shape of horns, and how the insulin receptor (InR) pathway modulates the size of male weapons in response to the larval nutritional environment. He recently starred in documentaries about his work for the BBC and NOVA, and released his first narrative nonfiction book for middle school readers, Beetle Battles: One Scientist’s Journey of Adventure and Discovery in December 2019. He is the grandson of John T. Emlen.
