Introduction of the hypothesis
The article says the Beau Geste hypothesis was introduced by John Krebs in 1977. But an earlier version of it was published in 1976 in chapter 7 of The Selfish Gene by Richard Dawkins, a colleague of Krebs at Oxford (It is possible that the reference to the hypothesis was added to a later edition of the book, so I may be wrong).
