Abstract

From northeastern Eurasia to the Americas, a three-stage spread of modern humans is considered through large-scale intermittence (exploitation/relocation). Conceptually, this work supports intermittence as a real strategy for colonization of new habitats. For the first stage, northeastern Eurasia travel, we adapt our model to archaeological dates determining the diffusion coefficient (exploitation phase) as D = 299.44 km²/yr and the velocity parameter (relocation phase) as v_o = 4.8944 km/yr. The relative phase weight (≈0.46) between both kinds of motions is consistent with a moderate biological population rate (r' ≈ 0.0046/yr). The second stage is related to population fragmentation. The last stage, reaching Alaska, corresponds essentially to relocation (v_o ≈ 0.75 km/yr).
