Societies with low-level food production economies occupy the vast and diverse middle ground between hunting–fishing–foraging and agriculture. Efforts by Ford, Harris, Rindos, Zvelebil, and others to characterize this in-between territory are discussed, and a new conceptual framework is proposed. Domestication, the central landmark of this middle ground, is situated well away from the boundaries with hunting–gathering and agriculture, and separates low-level food production economies into two broad categories. Key issues and questions concerning societies with low-level food production, both with and without domesticates, are discussed. Hunter–gatherer and agriculture boundary zones on either side of the middle ground are considered, as are the developmental pathways that traverse them. 相似文献

Synthetic biology is an emerging technology that will impact on the future security and prosperity of Australia. As a discrete policy area synthetic biology has not been explored in relation to Australian foreign policy. To begin this process an understanding of Australia’s genetic endowment, Australia’s agricultural endowment and those security concerns novel to synthetic biology need to be developed. The convergence of the biological sciences and the information sciences is creating novel security concerns that impact on Australian sovereignty, both mainland and the Antarctic Territories, plant and animal health, and defence medical infrastructure. These concerns cross many traditional disciplinary and policy boundaries, an awareness of this is required and a nascent national practitioner community can develop this further. Drawing from work conducted by the US and UK synthetic biology practitioner communities, this article lays out the unique touch points synthetic biology has on Australian foreign policy. 相似文献
