Modeling of spreading processes has gained a lot of attention in the last decades, since these processes play a crucial role in understanding a wide range of real-world systems that span biological, technical, economical and social sciences. However, very little is known about processes/systems that have happened in ancient times, available data is sparse and we can not observe these systems again.
In this talk, we will present an agent-based model for the spreading of the wool-bearing sheep in a population of herders in the Near East and Europe, between 6200 and 4200 BC. In our model, the herders are represented by agents moving diffusively in a geophysical landscape and simultaneously interacting with other agents. The diffusion of the innovation is thus happening on a spatial network that is changing in time, as the connections between the agents are changing in time due to their movements. We will use our model to explore the dynamical properties of the spreading process and to study the qualitative effect of different aspects affecting the speed and spatial evolution of this spreading process.
