New Rules: S (Sex) and I (Inheritance) Emergent Phenomena I (G1, M, S):

Natural Selection (vision, metabolism) Fitness - sustainable co-evolution Population Oscillations (modified S)

Emergent Phenomena II (G1, M, S, I): I retards natural section I increases wealth inequality

Cultural TransmissionCultural Transmission

New agent property: cultural tag Culture rule (K) includes both tag-flipping

and tag majority Vertical/Horizontal cultural transmission Emergent Phenomena (G1, M, K):

Convergence to one culture (I.e. K is sufficient to generate cultural groups

Desire for sugar produces migration and spatial segregation.

Each sub-population converges to pure red or blue

Sexual reproduction increases each tribe’s population…forcing migration down the mountain.
