Sexual Selection: Sperm in the Fast Lane
Sperm competition has led to spectacular adaptations in males and their ejaculates. A recent study of Tanganykan cichlids provides compelling evidence that sperm competition can drive the evolution of faster, longer sperm.
متن کاملPostcopulatory sexual selection influences baculum evolution in primates and carnivores
The extreme morphological variability of the baculum across mammals is thought to be the result of sexual selection (particularly, high levels of postcopulatory selection). However, the evolutionary trajectory of the mammalian baculum is little studied and evidence for the adaptive function of the baculum has so far been elusive. Here, we use Markov chain Monte Carlo methods implemented in a Ba...
متن کاملSexual Selection and the Evolution of Brain Size in Primates
Reproductive competition among males has long been considered a powerful force in the evolution of primates. The evolution of brain size and complexity in the Order Primates has been widely regarded as the hallmark of primate evolutionary history. Despite their importance to our understanding of primate evolution, the relationship between sexual selection and the evolutionary development of bra...
متن کاملComparative and Theoretical Approaches to Studying Sexual Selection in Primates
Primates exhibit amazing variation in traits that are likely to have arisen through sexual selection. Many of these traits play a role in visual or chemical communication. The striking countenance of a dominant male mandrill serves as a classic example [Setchell]. Scent marking in callitrichids is another form of communication that may be sexually selected [Heymann], while dichromatism is a com...
متن کاملFemale remating, sperm competition and sexual selection in Drosophila.
Female remating is fundamental to evolutionary biology as it determines the pattern of sexual selection and sexual conflict. Remating in females is an important component of Drosophila mating systems because it affects sperm usage patterns and sexual selection. Remating is common in females of many species of Drosophila in both natural and laboratory populations. It has been reported in many in...
