Explore the fascinating world of animal dominance hierarchies in this comprehensive lecture by Elizabeth Hobson, Assistant Professor at the University of Cincinnati and former ASU-SFI Fellow. Delve into a century of pecking order research, examining how social creatures encode environmental information through power relationships. Investigate the mechanisms underlying both human and animal nature, including who wins, who loses, and at what cost. Discover the latest developments in the field, from quantitative analysis to literature reviews, and gain insights into the current state and frontiers of dominance hierarchy science. Learn about the implications of these hierarchies for social structures, inequality, and institutional legitimacy in both animal and human societies.
