Paleoethnobotany in the Neotropics from Microfossils: New Insights into Ancient Plant Use and Agricultural Origins in the Tropical Forest

Analysis of plant microfossils (phytoliths, pollen, and starch grains) from archaeological and paleoecological sediments in the humid Neotropical forest can provide information on some formerly intractable problems in American paleoethnobotany and archaeology. Each technique has strengths that redress the other's shortcomings, and all three microfossils can be recovered from early sites, securely identified, and dated. Agricultural origins, Pleistocene/ Holocene environmental changes, and the evolution of slash-and-burn agriculture are three important issues that yield substantial results to phytolith, pollen, and starch grain study. Microfossils of a number of domesticates, including maize, manioc, squash, bottle gourd, arrowroot, and leren, have been identified in contexts dating from 9000 to 7000 radiocarbon years B.P. The scope and methodology of traditional paleoethnobotany should be expanded to routinely include microfossil study.     

Historical ecology coming of age

Historical ecology is a research program that in earnest has emerged within anthropology since the turn of the millennium. This essay offers a short outline of historical ecology and, on the basis of a review of four volumes published over the last decade, discusses several key issues in the historical ecological analyses of socio-environmental relations. It is argued that historical ecology (1) emerged as a concept in different, but related, discursive contexts, (2) coalesced in North American anthropology and anthropological archaeology, and (3) subsequently cross-fertilized and diversified in new academic milieus successfully addressing previously unconsidered research questions in novel ways.
