Resumen:
The tempo and mode of the initial human dispersal in theAmericas is a keyissue for the study of its ulterior variation and diversity through time. We presenta demographic model to explore the population dynamic on the base of paleoenvironmentalreconstructions between the ca. 18 and 10 kybp and differentdispersal simulations are presented by considering a fast invasive process anda slow one. The model used Fisher equation plus a term related to carryingcapacity; when population density achieved certain threshold, it has to move tothe best neighbor environment. Our population dispersal model depends onpopulation growth, diffusion and a minimum population to produce a migration.The equation considers gender differences in the populations and alsoestimates the reproduction probability for men and women.
