A single-pheromone model accounts for empirical patterns of ant colony foraging

This paper critiques the two-pheromone model (2PM) proposed by Dussutour et al. for ant foraging behavior, demonstrating that a single-pheromone model (1PM) can adequately explain the observed patterns. The authors argue that the evidence for a two-pheromone system is not definitive and advocate for further comparative modeling of cognitive mechanisms in animal behavior.
