“…This mechanism requires that reproductive suppression be imposed by aggression and related stress e¡ects, active interference with copulation, pheromonal cues that block ovulation and infanticide. For example, in some cooperatively breeding monkeys (cotton-top tamarin Saguinus oedipus (Savage et al 1988) and common marmoset Callithrix jacchus (Barret et al 1990)), both behavioural and olfactory signals appear to be implicated in reproductive suppression. In contrast, the self-restraint model (SRM) does not involve aggression directed towards non-breeding females.…”

Colonies of Damaraland mole-rats Cryptomys damarensis exhibit a high reproductive skew. Typically one female breeds and the others are anovulatory. Two models, the dominant control model (DCM) and the self-restraint model (SRM), have been proposed to account for this reproductive suppression. The DCM proposes that suppression is under the control of the dominant breeder and is imposed by mechanisms such as aggression, pheromones and interference with copulation, whereas the SRM does not involve aggression directed towards non-breeders and may function in order to minimize inbreeding. We investigated potential proximate mechanisms involved in the suppression of females in a series of experiments. Socially induced stress through aggression did not appear to be responsible for anovulation. Nor did breeders actively interfere with subordinate copulation. Females were physiologically suppressed when housed in intact colonies. However, as predicted by the DCM, they did not become reproductively active when removed from the presence of breeders. We found no evidence that pheromonal cues block ovulation. We suggest that the SRM is the basic model found in the Damaraland mole-rat and that selfrestraint functions in order to minimize inbreeding by restricting reproduction until an unrelated male is present. This would explain the rapid onset of reproductive activation in females when paired with an unrelated male, as demonstrated in this study.

“…Pheromones are thought to play a role in behavioural regulation in prosimians and new world monkeys [1,2], although the effects of pheromones on behaviour do not appear to be as significant in primates as in small-brained mammals [3]. While prosimians and new world monkeys possess a VNO and functioning vomeronasal system, the VNO and AOB appear to have become vestigial in catarrhine primates approximately 23 million years ago.…”

Small-brained rodents have been the principle focus for pheromonal research and have provided comprehensive insights into the chemosensory mechanisms that underpin pheromonal communication and the hugely important roles that pheromones play in behavioural regulation. However, pheromonal communication does not start or end with the mouse and the rat, and work in amphibians reveals much about the likely evolutionary origins of the chemosensory systems that mediate pheromonal effects. The dual olfactory organs (the main olfactory epithelium and the vomeronasal organ), their receptors and their separate projection pathways appear to have ancient evolutionary origins, appearing in the aquatic ancestors of all tetrapods during the Devonian period and so pre-dating the transition to land. While the vomeronasal organ has long been considered an exclusively pheromonal organ, accumulating evidence indicates that it is not the sole channel for the transduction of pheromonal information and that both olfactory systems have been co-opted for the detection of different pheromone signals over the course of evolution. This has also led to great diversity in the vomeronasal and olfactory receptor families, with enormous levels of gene diversity and inactivation of genes in different species. Finally, the evolution of trichromacy as well as huge increases in social complexity have minimised the role of pheromones in the lives of primates, leading to the total inactivation of the vomeronasal system in catarrhine primates while the brain increased in size and behaviour became emancipated from hormonal regulation.

“…Early analyses of the VS debated the pheromonal versus nonpheromonal functions of this system in primates (Stephan et al, 1982), and it seems necessary to revisit this discussion based on the functional overlap of the MOS/VS in some other mammals. It is also critical to emphasize that although New World anthropoids apparently possess an intact VS (i.e., possess the receptor organ, vomeronasal nerves, and an accessory olfactory bulb), there is no convincing evidence whatsoever that it is functional for pheromone (or any odorant) detection (Barrett et al, 1990). In strepsirrhines, there is reason to believe the VS is critical for pheromonal communication (Aujard, 1997;Alport, 2004, this issue;Kay et al, 2004, this issue).…”

Evolution of the special senses in primates: Past, present, and future

The present special issue of The Anatomical Record is the result of a symposium entitled Evolution of the Special Senses in Primates. Considered together, the special senses of primates are remarkable because they constitute a singular and definitive suite of mammalian characteristics. Examining their evolution is pivotal for understanding the origin and present-day variation of primate behavior and ecology. Accordingly, the 14 articles assembled here consider the different constraints and opportunities associated with the uptake and use of physical and chemical stimuli. The present issue brings together experts on different primate sensory modalities and stresses events at the sensory periphery, where the organism is exposed to and comes into contact with its environment. Key topics include color vision, the genetics of olfaction, the morphological basis and significance of chemical communication, and the neural organization and scaling of primate sensory systems. The result is a special issue that both reflects our current understanding of primate sensory modalities and challenges certain fundamental assumptions concerning their evolution. © 2004 Wiley-Liss, Inc. Key words: audition; gustation; olfaction; touch; vision; vomeronasalThis special issue of The Anatomical Record is the result of a symposium held during the 73rd annual meeting of the American Association of Physical Anthropologists. The symposium was the suggestion of Timothy D. Smith; the conveners were Nathaniel J. Dominy, Callum F. Ross, and Timothy D. Smith. It was presented in Tampa, Florida, on 17 April 2004. The title of the symposium and the present issue is Evolution of the Special Senses in Primates. We focus on primate special senses (vision, audition, olfaction, and gustation) for the same reasons the topic has already received much attention (Le Gros Clark, 1959;Noback, 1978;Martin, 1990)-because humans are primates and because there is a unique complexity in the expression of primate special senses. Two contributions to this issue consider the evolution of somatosensation, which also bears pivotal importance to the origin of Primates.Senses represent the anatomical interface between the environment and the behaving organism. The 14 articles assembled here emphasize the constraints and opportunities associated with sensing environmental information. The articles also examine the selective pressures in the evolution and behavioral ecology of primates; after all, the survival and reproductive success of an organism depends on the acquisition of sensory stimuli. In this regard, primates do not eat or reproduce with whatever is available; instead, they show considerable selectivity. A mixture of many analytically separable factors is locked together in a potential food resource or mate. These factors can be conveniently differentiated into two broad categories: physical and chemical. Accordingly, the following synopsis describes the contributions of the present special issue to our understanding of primate sensory systems within the...
