Understanding the mechanisms underpinning complex sociality. This project aims to investigate the mechanisms underlying the formation of complex social systems in vertebrates. Our understanding of these mechanisms is strongly biased towards a few model systems. We have identified a novel Australian model system with a wide range of sociality for this purpose. This project expects to generate new knowledge on how the social environment interacts with the brain during social organisation.

Our understanding of these mechanisms is strongly biased towards a few model systems. We have identified a novel Australian model system with a wide range of sociality for this purpose. This project expects to generate new knowledge on how the social environment interacts with the brain during social organisation. Expected outcomes include the refinement of social theory and capacity building via international collaboration and postgraduate training. This work will provide significant benefits by increasing our understanding of how the brain and social environment interact to moderate aggression and enhance social associations.Read moreRead less
Plasticity and the origins of family. This project aims to answer the question of how family life evolved. Humans and many animals live in stable family groups because of the benefits of cooperation. Surprisingly, we have a very poor understanding of how family living initially evolved. This project will experimentally determine how simple responses to environmental change have driven the evolution of family living and thereby refine theories for understanding social evolution more generally. ....Plasticity and the origins of family. This project aims to answer the question of how family life evolved. Humans and many animals live in stable family groups because of the benefits of cooperation. Surprisingly, we have a very poor understanding of how family living initially evolved. This project will experimentally determine how simple responses to environmental change have driven the evolution of family living and thereby refine theories for understanding social evolution more generally. This information will be useful to environmental policy makers that need to consider the role of environmental change in managing and conserving viable populations.Read moreRead less
How mates and sexual rivals affect reproductive costs, lifespan and ageing. This project aims to dissect the complex costs of reproduction, bridging an old divide between evolutionary and biomedical approaches to understanding ageing and lifespan. Merely detecting the smell of another individual, without ever encountering them, can cause an individual to mature sooner, age faster, or live a shorter life. These costs, and the fact that subsequent mating can restore adult ageing and lifespan to "n ....How mates and sexual rivals affect reproductive costs, lifespan and ageing. This project aims to dissect the complex costs of reproduction, bridging an old divide between evolutionary and biomedical approaches to understanding ageing and lifespan. Merely detecting the smell of another individual, without ever encountering them, can cause an individual to mature sooner, age faster, or live a shorter life. These costs, and the fact that subsequent mating can restore adult ageing and lifespan to "normal" are causing a re-evaluation of the costs of reproduction - an important but enigmatic concept in evolution. This project expects to resolve how and why the physical presence of a mate, or odour cues of such a mate, can have such dramatic effects on ageing and late-life performance.Read moreRead less
