Evolving The Selfish Herd: Emergence Of Distinct Aggregating Strategies In An Individual-Based Model, Proc. Biol. Sc.

Excerpts: From zebra to starlings, herring and even tadpoles, many creatures move in an organized group. The emergent behaviour arises from simple underlying movement rules, but the evolutionary pressure which favours these rules has not been conclusively identified. (...) Here, we adopt an individual-based model for group formation and subject it to simulated predation and foraging (...). We draw analogies with multiple Nash equilibria theory of iterated games to explain and categorize these behaviours. Our model is sufficient to capture the complex behaviour of dynamic collective groups, yet is flexible enough to manifest evolutionary behaviour.
