Sebastian Sosa

I am a junior researcher studying animal societies, with a specific focus on the underlying mechanisms that contribute to the emergence of distinct social structures and their adaptive properties. Questions such as how individuals interact within these societies and how social structures evolve to address challenges posed by natural selection (such as group cohesion and hierarchical organization) are currently being explored through multilevel and multi-methodological analyses, including social networking and referential statistics. These analyses aim to comprehend the structural processes within animal societies, as well as the ecological and evolutionary implications on these structures and their emergent characteristics.
