Encyclopedia > Demic diffusion

An archaeological term that refers to population diffusion into and across an area previously uninhabited by that group, possibly displacing, replacing, or intermixing with a pre-existing population (e.g. as has been suggested for the spread of agriculture across Neolithic Europe, and what occurred with the European colonization of the Americas).

Earlier work had considered diffusion as a mechanism, but only in terms of a `cultural' diffusion where technology was passed between indigenous peoples without significant actual movement of population.
The model solves the demic equation (essentially a diffusive spread of population plus a local logistic term representing population dynamics) on a realistic map of Europe.
In this instance, the demic diffusion dominates over the technology diffusion and the convert population in overwhelmed by the advancing farmers.
