Hunter-Gatherers Delayed Farming

Our Ancestors’ Fight for Space

ScienceDaily (Dec. 3, 2010) — Agricultural — or Neolithic — economics replaced the Mesolithic social model of hunter-gathering in the Near East about 10,000 years ago. One of the most important socioeconomic changes in human history, this socioeconomic shift, known as the Neolithic transition, spread gradually across Europe until it slowed down when more northern latitudes were reached.

Research published Dec. 3, 2010, inNew Journal of Physics (co-owned by the Institute of Physics and the German Physical Society), details a physical model, which can potentially explain how the spreading of Neolithic farmers was slowed down by the population density of hunter-gatherers.

The researchers from Girona, in Catalonia, Spain, use a reaction-diffusion model, which explains the relation between population growth and available space, taking into account the directional space dependency of the established Mesolithic population density.

The findings confirm archeological data, which shows that the slowdown in the spreading of farming communities was not, as often assumed, the result of crops needing to adapt to chillier climates, but indeed a consequence of the struggle for space with prevalent hunter-gatherer communities.

In the future, the researchers’ model could be used for further physical modeling of socioeconomic transitions in the history of humanity. As the researchers write, “The model presented in this work could be applied to many examples of invasion fronts in which the indigenous population and the invasive one compete for space in a single biological niche, both in natural habitats and in microbiological assays.”

About carlos

I'm a curious person, of reasonable intellect, "on the beach" (retired) and enjoying my interest in anthropology, language, civil rights, and a few other areas. I've been a hippie/student/aerospace tech writer in the '60s, a witness to the Portuguese revolution in the ‘70s, a defense test engineer and witness to the Guatemalan genocide in the '80s, and a network engineer for an ISP in the '90s. Now I’m a student and commentator until my time is up. I've spent time under the spell of the Mesoamerican pyramids and the sweet sound of the Portuguese language. I've lived in Europe, traveled in Brazil, Central America, Iceland, New Zealand, and other places. My preferred mode of travel is with a backpack and I eat (almost) anything local. Somehow, many of the countries I have been to have had civil unrest (for which I was not responsible). I'm open to correspond with anyone who might share my liberal, humanist interests. I live in San Buenaventura, California.
