Table 1 List of key parameters

Name	Description	Values
R	Number of resources species	250
Q _r	Maximum energy reward of resource	N(0.1,0.1)
	type r
H _r	Practice time needed before obtaining
	half the maximal reward	0.1..10
S _r	Scalar for the sigmoid function
	describing how rewards increase
	with practice	1..4
EC	Rate at which resource
	types are replaced by new types	0..R types per year
N	Population size	100
G	Maximum number of foragers in a group	20
COPY_SPACE	Distance at which foragers
	can observe what their neighbors	20
	are doing
K	Effectiveness of
	observational learning	0.1
λ _i	Reinforcement learning rate	0..1
ε _i	Exploration rate	0..1
γ _i	Stimulus enhancement	0..1

Upper case letters and names: invariant parameters that do not change during simulations. Greek letters: parameters that can evolve but are invariant during a forager’s lifetime. Subscripts: i= forager identity; r= resource type
