Fig. 4: Division of labour, nutrition level and dominance of nursing and foraging individuals.
From: Resource sharing is sufficient for the emergence of division of labour
a1 Dominance-based sharing. Division of labour reaches maximal levels of D = 1. Nursing and foraging individuals exhibit a bimodal distribution of nutrition levels. a2 Nutrition levels of individuals diverge over simulation time, depending on the individual’s dominance. b1 Nutrition-based sharing. Division of labour again reaches maximal levels of D = 1, and nutrition levels exhibit a bimodal distribution. b2 Nutrition levels of individuals diverge over simulation time. a1 + b1 For graphical conventions, see Fig. 2. a2 + b2 Each line shows the nutrition level of an individual over the first 20% of simulation time from a representative replicate simulation, coloured according to the individual’s dominance value if dominance values were pre-assigned.
