Abstract : Pheromones are chemical signals between members of
the same species. Since the discovery of the silk moth sex pheromone in
1959, pheromones have been identified in animals all across the animal
kingdom. They work just as well underwater: fish and lobsters also use
pheromones. Pheromones offer remarkable opportunities to study the
evolution of signals and changes in signal and receiver during speciation,
from enzyme pathways to receptors and neurons, at every level from genes to
populations. But do humans have pheromones? A corporation claimed they had
found them but never provided evidence. I will describe this ?bad science?
and how we might answer the question properly.
The talk will be designed for non-specialists and specialists alike.
Bio: Tristram Wyatt is a member of the Animal Behaviour Research Group of
the Department of Zoology, University of Oxford and an emeritus fellow of
Kellogg College, Oxford. Before coming to Oxford?s Department for
Continuing Education as a lecturer (Associate Professor) in 1989, he was a
lecturer at the University of Leeds and held research fellowships at the
University of California, Berkeley and the University of Wales, Cardiff.
He is interested in how animals of all kinds use pheromones to communicate
by smell. The second edition of his single-author book *Pheromones and
Animal Behavior *(Cambridge University Press) won the Royal Society of
Biology?s prize for the Best Postgraduate Textbook in 2014. His TED talk
on human pheromones has been viewed over a million times. His new book
is Animal behaviour: A Very Short Introduction, published by Oxford University Press
in February 2017.
