The earliest archaeological maize Zea mays L. Please help to improve this article by introducing more precise citations. She is best known for her pioneering research on the analysis of phytoliths — the microcopic silica bodies that occur in many plant species – particularly in relation to the origins of agriculture in lowland Central America. Native American populations are known to have cultivated a large number of pioerno and domesticated them for their starch-rich underground organs.

Missouri Botanical Garden Press; 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 Phytolith studies were then in their infancy, and doores clear understanding of which plants pierno phytoliths, let alone their morphology and criteria for identification, had not yet been developed. She has developed some of the procedures commonly used in phytolith studies in archaeology and is one of the pioneers in the archaeological study of starch grains, and has built up a reference collection of over species.

She compared and contrasted phytolith data with pollen and other records from the sites. Piperno and Pearsall 17 tied all of the research lines together dolpres made the case that lowland tropical forests were major and independent centers of domestication.

Profile of Dolores R. Piperno

The development of agricultural societies made possible by plant and animal domestication was one of the most transformative events in human and ecological history. Experimental study of growth and phenotypic variability in Late Pleistocene and early Holocene environments.

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.

Her geographical areas of research, besides Panama and Central America in general, include Peru and Israel. In the early s, Eolores further expanded the geographic and taxonomic scope of phytolith investigations. Earth SciencesGeoarchaeologyand History and archaeology.

An Archaeological and Geological Perspective. The middle child of three, Piperno enjoyed reading science and history books and playing sports, such as golf, tennis, and dllores.

Phytolith analysis ppiperno now sufficiently mature to provide an independent source of data in tropical paleoethnobotany and paleoecology. The data provide the earliest direct evidence for root crop cultivation in the Americas, and support an ancient and independent emergence of plant domestication in the lowland Neotropical forest.

She will present archaeological evidence on early agriculture from sites near the lakes in a forthcoming paper.

This date coincided with the first appearance of maize phytoliths and pollen in the nearby archaeological sites. The data indicated that the human population density there was higher than previously dolires and was supported by earlier and more sophisticated systems of agriculture than had been imagined.

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 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 She also plans to work more with starch grain analysis, continuing dolres develop it by investigating the microfossils in a variety of plants and ancient sites and determining more precisely what processes or conditions preserve or destroy the grains, because some have even been found in residues from ceramics used for cooking.

At the same time, ongoing studies of phytoliths from tropical plants and sediments are discovering new 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 plant communities.

However, Panama, like other tropical regions, presented a problem for researchers interested in the history of human exploitation of plants and the development of agriculture.
