Previous studies have discussed the evolution of ownership using the Hawk–Dove–Bourgeois game. Decisive parameters are resource values ( V ) and contest costs ( C ). However, ownership may also evolve as a result of the effects of population density. To compare the effects of population density with those of resource values, I created a learning‐based model of a revised Hawk–Dove–Bourgeois game. The game simulates the dynamics of agents that struggle for regions (“territories”) along a line. With appropriate sets of r (resource value) and l (reciprocal of the population density), the model showed that ownership is more likely to evolve when the resource value is small and population density is high. An area containing high‐value resources is likely to accompany high population density. However, simulations showed that population density has stronger effects than resource value on the evolution of ownership.
