I study the evolution of sociality and ask why social relationships are formed and how they are maintained. Within groups of animals, individuals differ in their tendency to interact with others and in how deeply embedded they are in their social network. Investigating these differences allows me to determine the genetic and physiological causes of sociality, as well as its impact on Darwinian fitness. My research is centred on wild or free-ranging populations with long-term datasets that permit me to quantify inter-individual differences in sociality, relatedness, survival and reproductive output.
I currently focus on two study systems - a highly gregarious primate, the rhesus macaque (Macaca mulatta), and a cetacean with a kin-focused social structure, the resident killer whale (Orcinus orca). In killer whales my primary work tests the hypothesis that individuals gain inclusive fitness benefits by forming social relationships with their relatives. In rhesus macaques, my work has provided some of the first evidence of the fitness benefits of sociality, showing that the infants of individuals who are more deeply embedded in their social network are more likely to survive. I have also shown that an individual’s position in their social network is both stable across time and heritable, confirming that sociality is under genetic control and is a trait on which selection may act.
I am member of the Centre for Research in Animal Behaviour at Exeter, and was formally a postdoctoral fellow in Cognitive Neuroscience at Duke University. Additional details about my research can be found at laurenbrent.com.
