Special Issue of Current Anthropology. Publications available in PDF. Their analyses of phytoliths and pollen from the lake cores found the same kinds of environmental shifts as in other regions of the lowland tropics, with a rapid and marked transition to the present warmer, wetter climate taking place at the end of doloers Ice Age approximately 10, years ago 5.

Phytolith analysis is now sufficiently mature to provide an independent source of data in tropical paleoethnobotany and paleoecology. In addition, Piperno plans another long-term collaboration with Mark Bush to study paleoecological records from the Amazon Basin and to determine past human impacts on biodiversity and forest structure there.

By that point I knew that I was interested in focusing on archaeobotany, and that summer in Panama I got hooked on the tropics. After earning a B. The earliest archaeological maize Zea mays L. Footnotes This is a Profile of a recently elected member of the National Academy of Sciences to accompany the member’s Inaugural Article on page Evidence from coastal Ecuador6 suggests that maize had been taken south across the equator by 7, years BP. Their combined citations are counted only for the pipeno article.

We postulate that the major effects of these conditions were to have brought montane vegetation m lower than its present range and to create tracts of open landscape along the Pacific coast. Multi-proxy analyses of lake sediments and terrestrial soils e.

The artefacts also contain maize starch Zea mays L. Through a review of recent studies in the New World tropics, this paper presents some contributions to, problems of, and prospects for phytolith analysis to inform the archaeological community about such issues as 1 the origins and dispersals of domesticated plants, 2 the development of tropical forest agriculture, 3 the uses of tropical plants in prehistory, and 4 the distribution and composition of past pipernk communities.

Paleoecological perspectives on human adaptation in central Panama.

With another phytolith researcher, Deborah Pearsall from the University of Missouri Columbia, MOPiperno set out to explore for the first time the wild ancestors of crops like maize and major plants from the Old World, such as rice, so that the plants could be studied in their areas of origin The Origins of Agriculture in the Lowland Neotropics. For the past 7 years, Piperno and her team have tackled the long-debated question of where and when maize was domesticated. Retrieved from ” https: My research interests have mainly involved the archaeology and human ecology of the lowland American tropics together with the biogeographical and climatological history of the tropical biome.

Latin American Antiquity 7 4, Open in a separate window.

These plants did not produce identifiable phytoliths and could not easily be traced through their pollen. The results verified the first set of starch data, providing evidence for an early use of manioc and yams, and corroborated previous phytolith data for maize MultidisciplinaryNatureand Maize.

Journal of Archaeological Science. I learned some valuable lessons and skills dolodes that 5-year period, including the importance of good microscopy work. Piperon completing her Ph. In the early s, Piperno further expanded the geographic piperjo taxonomic doloree of phytolith investigations. She will present archaeological evidence on early agriculture from sites near the lakes in a forthcoming paper. The silica bodies of tropical American grasses: To remedy that, Piperno and her colleagues have been studying lakes and archaeological sites in the region 5.

A multidisciplinary approach to scientific questions and close collaboration with geneticists, plant physiologists and other scholars will piece together a reliable picture of the past. Click here to sign up. She turned to microfossils called phytoliths, mainly used by North American soil scientists in their research. In archaeobotanist’s hands, tiny fossils yield big answers”.

By the late s, Piperno felt that she had a grip on the early cultivation and dispersals of maize and other seed crops, such as squashes, in Panama and northern South America. Experimental study of growth and phenotypic variability in Late Pleistocene and early Holocene environments. Views Read Edit View history. Plant domestication was at its core an evolutionary process involving both natural and human selection for traits favorable for harvesting and consumption.

In the core sediments, Piperno and her colleagues found phytolith and pollen evidence of significant forest modification from humans practicing slash-and-burn cultivation starting 7, years ago. Few researchers, however, had undertaken archaeological or paleoecological work there, says Piperno.

As botanists and other researchers have long known, starch grains, microscopic particles where plants store their energy, are often diagnostic of a plant’s genus and even species.
