Do humans have pheromones? Tristram Wyatt is on the case. A researcher at Oxford, Wyatt is interested in the evolution of pheromones throughout the animal kingdom.

Why you should listen

Tristram Wyatt wants to understand the messages that animals send with their smell. At Oxford, he researches the intersection of pheromone evolution and animal behavior, particularly in mammals. He's interested in the distinction between pheromones, the chemical signals a species produces, and each individual's signature mixture of distinct molecules. The zoologist has discovered some surprising biological coincidences along the way — like the fact that Asian elephants have the same female sex pheromones as 140 species of moths.

Wyatt is the author of Pheromones and Animal Behavior.

Do our smells make us sexy? Popular science suggests yes — pheromones send chemical signals about sex and attraction from our armpits. But, despite what you might have heard, there is no conclusive research confirming that humans have these smell molecules. In this eye-opening talk, zoologist Tristram Wyatt explains the fundamental flaws in current pheromone research, and shares his hope for a future that unlocks the fascinating, potentially life-saving knowledge tied up in our scent.
