Abstract

The transition from a mobile hunter-gatherer lifestyle to one of settled agriculture is arguably the most fundamental change in the development of human society (Lev-Yadun et al., 2000). The establishment of agricultural economies, emerging initially in the Fertile Crescent of the Near East (Nesbitt, 2002), required the domestication of crops; ancient plant remains recovered from early farming sites provide direct evidence for this process of domestication. Archaeobotanical remains are typically preserved through charring (partial to complete carbonisation through exposure to heat) and recovered during archaeological excavation (Charles et al., 2015). Seeds of the same species, recovered from different sites and periods, can sometimes be seen to exhibit morphological differences, which may have arisen owing to variations in cultivation practices, climate, soils and altitude, etc. To explore these possibilities, morphological variation in seeds of wheat and barley between archaeological sites was recorded and mapped both in time and space. Results presented here suggest that modern morphometric approaches may help to test some long-debated hypotheses and pave the way for new insights into the evolutionary origins of agriculture in western Asia.

现代形态计量学研究农业起源的第一步
从流动的狩猎采集生活方式向定居农业生活方式的转变可以说是人类社会发展中最根本的变化(Lev-Yadun et al., 2000)。农业经济的建立,最初出现在近东新月沃土(Nesbitt, 2002),需要驯化作物;从早期农业遗址中发现的古代植物遗骸为这一驯化过程提供了直接证据。考古植物遗骸通常通过炭化(通过暴露于热而部分或完全碳化)保存,并在考古发掘中恢复(Charles et al., 2015)。同一物种的种子,从不同的地点和时期恢复,有时可以看到表现出形态上的差异,这可能是由于耕作方式、气候、土壤和海拔等方面的差异造成的。为了探索这些可能性,在不同的考古遗址之间记录和绘制了小麦和大麦种子在时间和空间上的形态差异。这里提出的结果表明,现代形态计量学方法可能有助于测试一些长期争论的假设,并为对西亚农业进化起源的新见解铺平道路。

期刊介绍: Web Ecology (WE) is an open-access journal issued by the European Ecological Federation (EEF) representing the ecological societies within Europe and associated members. Its special value is to serve as a publication forum for national ecological societies that do not maintain their own society journal. Web Ecology publishes papers from all fields of ecology without any geographic restriction. It is a forum to communicate results of experimental, theoretical, and descriptive studies of general interest to an international audience. Original contributions, short communications, and reviews on ecological research on all kinds of organisms and ecosystems are welcome as well as papers that express emerging ideas and concepts with a sound scientific background.
