Fig. 2: Division of labour and nutrition levels of nursing and foraging individuals under no resource sharing and equal sharing.
From: Resource sharing is sufficient for the emergence of division of labour
a No sharing. In the absence of resource sharing, D = −1 which indicates that individuals alternate between nursing and foraging. As foraging is triggered by a decline in the nutrition level, nursing individuals have a higher nutrition level than foragers. b Equal sharing. If foraging individuals share their collected resources equally with nursing individuals, D ≈ 0.6 which represents an intermediate level of division of labour. Each grey dot (left panel) is the division of labour metric from a replicate simulation (n = 20). Blue (nursing) and green (foraging) dots (right panel) represent the nutrition levels of all individuals at the end of all replicate simulations.
