Evolution rewards competition for resources and mates, yet acts of self-sacrifice, on first appearances, appear to disadvantage the individual. In this talk, Amanda uses examples in the animal kingdom to explore human co-operation and altruism.

Amanda Ridley has devoted her career to understanding the causes and consequences of social behaviour. She is a behavioural ecologist based at the University of Western Australia.

After a career in wildlife management, Amanda undertook a PhD at Cambridge University where her eyes were opened to the fascinating world of animal behaviour. Amanda’s fieldwork took her to the Negev Desert in the Middle East, and onward to the Kalahari desert in southern Africa as part of a postdoctoral collaboration between Cambridge University and the University of Cape Town.

In 2012, Amanda began research on the Western Australian magpie. She is leading two longitudinal research projects and has authored over 50 scientific articles. In 2015, Amanda was nominated as a Rising Star in the UWA Faculty of Science.
