The introduction and emergence of agriculture into Eastern North America and Europe proceeded very differently: it varied in timing, speed, and mechanism—despite similar woodland environments. To resolve the different subsistence paths, I employ the Global Land Use and technology Evolution Simulator, a numerical model for simulating demography, innovation, domestication, migration and trade wit...
The application of established immunological and chemical methods to the analysis of archaeological organic residues offers a new scientific means of evaluating prehistoric subsistence and ecology. Recent studies demonstrate that animal and plant protein residues are often preserved on artifacts for many years after their original use and that such residues can be identified to at least the fam...
In the present paper we advance a theory of pre-industrial growth where body size and population size are endogenously determined. Despite the fact that parents invest in both child quantity and productivity enhancing child quality, a take-off does not occur due to a key “physiological check”: if human body size rises, subsistence requirements will increase. This mechanism turns out to be instr...
This article provides a review of selected literature of nonhuman primates in the subsistence and symbolism of indigenous lowland South American groups. While few works have focused specifically on the relationship between human and nonhuman primates in Amazonia and the surrounding areas, a number of ethnographic works do incorporate information about the roles of monkeys in varied groups. The ...
The transition from hunting and gathering to farming involved a major cultural innovation that has spread rapidly over most of the globe in the last ten millennia. In sub-Saharan Africa, hunter-gatherers have begun to shift toward an agriculture-based lifestyle over the last 5,000 years. Only a few populations still base their mode of subsistence on hunting and gathering. The Pygmies are consid...
BACKGROUND Farming communities have continuous interactions with their environment. Subsistence farmers are particularly vulnerable to the vagaries of weather. These are pre-requisites for increased wild edible plant consumption. This study mainly focused on indigenous knowledge regarding identity and use of wild edible plant species by the subsistence farmers of Obalanga. METHODS A multistag...
