Lars Kulik studied biology, with a particular focus on the development of social behavior in monkeys. He was interested in seeing how the animals grew into their social systems and how they arrived at the social patterns typical of their species. It is commonly assumed that these patterns are fixed, but there are hints that they are much more flexible than we think. The question of what needs to occur for these social rules to change is one that is also hotly debated with regard to our human culture—and it seems increasingly important to find some answers to this question. For Lars, it is clear that the answers are achievable only through an interdisciplinary approach, and therefore he was very interested in participating in the Anthropocene Curriculum and in contributing his knowledge about our biological roots.
