REMINDER - SEMINAR TODAY ’Gamilaraay Kinship Dynamics’ Jared M. Field (The University of Melbourne) Thursday 18 March 3.30pm - 4.30pm Carslaw 350 (University of Sydney staff and students only) and via Zoom, register here: https://uni-sydney.zoom.us/meeting/register/tZAkfu2vrDkiE9YG6ZP15uuGnUByeDB07t-K Abstract: Traditional Indigenous marriage rules have been studied extensively since the mid 1800s. Despite this, they have historically been cast aside as having very little utility. Here, I will walk through some of the interesting mathematics of the Gamilaraay system and show that, instead, they are in fact a very clever construction. Indeed, the Gamilaraay system dynamically trades off kin avoidance to minimise incidence of recessive diseases against pairwise cooperation, as understood formally through Hamilton’s rule. Biography: Jared Field completed his undergrad studies at the University of Sydney in maths and French literature, before reading for a DPhil in Mathematical Biology at Balliol College, Oxford. He is now a McKenzie Fellow in the School of Mathematics and Statistics at the University of Melbourne with broad interests at the intersection of mathematics, evolution and ecology.
