Kith selection: simple theory, complicated amoebas and bacteria
Commentator: Johannes Martens (IHPST, CNRS & Paris 1 Panthéon Sorbonne)
The evolution of cooperation is well understood when the cooperators are relatives but perhaps less so when they are unrelated. We will explore two aspects of evolutionary interactions among non-relatives, which we call kith selection. On the theoretical side, we show how these interactions can be expressed in form exactly parallel Hamilton’s rule. On the empirical side, we describe a complex “farming” symbiosis between Burkholderia bacteria and Dictyostelid amoebas.
