SEEM Seminar - The evolution of vocal communication is the result of multiple selection pressures, among which social life plays an important role. Indeed, different types of information must be reliably encoded in vocalizations according to the social needs of the species. In this presentation, I will first examine the influences [...]
Sexual bulges in primates have long sparked debate about their function - do they reliably indicate female fertility, or do they deceptively blur it? Here, we provide evidence that female primates can manipulate sexual swellings to outwardly indicate fecundity while inwardly failing [...].
"Orangutan life cycle: slow but sure" Among our closest extant relatives, the life of orangutans remains the least documented and understood, mainly due to their solitary lifestyle. Based on a 15-year study of Bornean orangutans (Pongo pygmaeus wurmbii), our research aims to [...]
The expensive brain and the evolution of brain size Vertebrate brains vary considerably in size, and this variation is often attributed to differing cognitive demands. Here, we ask whether the unusually high costs of brains have acted as constraints on the evolution of brain size. We confirm that [...]
