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 northeastern Eurasia travel, the first stage, 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 phaseweight (≈ 0.46), between both kind of motions, is consistent with a moderate biological population rate (r'≈ 0.0046 [1/yrs]). The second stage is related to population fragmentation. The last stage, reaching Alaska, corresponds essentially to relocation ( v_o ≈ 0.75[km/yr]).
