TL;DR: In a group of free-ranging baboons, Papio cynocephalus ursinus, the offspring of females who formed strong social bonds with other females lived significantly longer than the offspring who formed weaker social bonds, providing the first direct evidence that social relationships among female baboons convey fitness benefits.

TL;DR: The human–chimpanzee split is dated to at least 7–8 million years and the population split between Neanderthals and modern humans to 400,000–800,000 y ago, which suggests that molecular divergence dates may not be in conflict with the attribution of 6- to 7-million-y-old fossils to the human lineage and 400,,000-Y-old bones to the Neanderthal lineage.

TL;DR: In another study, this paper found that nonhuman primates are more likely to alarm call in response to a snake in the presence of unaware group members than in presence of aware group members, suggesting that they recognize knowledge and ignorance in others.

TL;DR: It is suggested that chimpanzees may actively modify pant hoots to be different from their neighbours, providing support for the vocal learning hypothesis.
