A discovery of the oldest known fossils from two major primate groups fills in a 10-million-year gap in the record and reveals new information about evolution
It is not in the least bit controversial to picture humans* within the context of the placental mammal group that we belong to, the primates.
Humans do it. Our great ape cousins, the bonobos, do it. Now researchers have documented western gorillas mating face to face in the wild.
A study published online in the journal Public Library of Science finds that male chimps who provide meat for females double their chances of mating over the long term. Steve Mirsky explains, with reporting by Adam Hinterthuer
An account of some curious preliminaries to mating among birds, insects and spiders, with particular reference to the influence of vision
The elaborate patterns of behavior that precede mating in some species present a puzzling biological problem. Their function is sought through the classic interplay of theory and experiment
As prehuman primates evolved into men, how did the primate horde evolve into the human band? One of the key changes seems to have been the subordination of sexual drives to the needs of the group
Dominance may not be key to mating of rhesus macaques
