The study, conducted on eland antelopes, has revealed the dominance displays used by males to settle disputes over access to fertile females, without resorting to genuine violence.

Led by Jakob Bro-Jorgensen from the Zoological Society of London and Torben Dabelsteen from the University of Copenhagen, researchers studied antelopes within a
