description: International symposium at the University of Tübingen, Germany, 8th-12th April 2001. This symposium explores the relationship between environmental change and the key events in the evolution and dispersal of the human clade, from its origin around 5-8 Myr to the expansion of Homo sapiens across the globe between 100 Kyr and 15 Kyr.
abstract: We have developed a simulation model of human dispersals which takes account of the effects of habitat variation on directions and rates of spread. The basic form of this model is a discrete approximation of Fisher-Skellam's wave of advance on a two-dimensional lattice. However, our model allows us also to examine the effects of a non-standard treatment of the mobility term, which takes account of taxis (advection-diffusion up gradients of resource concentration). We use this model to predict the archaeological signatures of human dispersal into the Americas, under different assumptions about the demography and adaptability of late glacial hunter-gatherers. We also report new radiocarbon dates for the peopling of southern South America, which were obtained to help us to evaluate the plausibility of these different sets of assumptions.
