Suggestions that the likely source of many of these crops, the tropical forest, was an early and influential centre of plant husbandry have long been controversial because the organic remains of roots and tubers are poorly preserved in archaeological sediments from the humid tropics.
Balter M July Piperno wanted to see if she could use phytoliths to discover the kinds of plants people ate in central Panama at the Aguadulce Rock Shelter, which Ranere excavated. The last years of the glacial period, from 20, B. Skip to main content. Email address for updates. Smithsonian Tropical Research Institute. Plant domestication was at its core an evolutionary process involving both natural and human selection for traits favorable for harvesting and consumption.
This article includes a list of referencesrelated reading or external linksbut its sources remain unclear because it lacks inline citations. InPiperno published the first book on using phytolith analysis for research in archaeology and environmental history In the Neotropics, many important crops such as maize, squashes, manioc, and yams can be identified.
Remember me on this computer. New articles related to this author’s research. The system can’t perform the operation now. Still not understood, for example, is when and how a human presence may have modified landscapes across the folores terra firme interfluvial forest zone of the Amazon Basin. As botanists and other researchers have long known, starch piperjo, microscopic particles where plants store their energy, are often diagnostic of a plant’s genus and even species.

Multi-proxy analyses of lake sediments and terrestrial soils e. 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 pilerno tropical forest agriculture, 3 the uses of tropical plants in prehistory, and 4 the distribution dolorss composition of past plant communities.
In the early s, Piperno further expanded the geographic and taxonomic scope of phytolith investigations.
The evidence also shows that the lakes became foci of early human activity and that farmers were clearing the forests in the lakes’ watersheds more than 6, years ago. DooloresPiperno and Pearsall published The Origins of Agriculture in the Lowland Neotropics 17in which they summarized the evidence collected over the last two decades for plant domestication and past natural and human impacts on tropical forest.
DavisFreelance Science Writer. The Origins of Agriculture in the Lowland Neotropics. Piperno also found that using pollen, phytolith, and charcoal data in tandem generated more robust environmental histories.
Specifically, because the microfossils entrap the contents of cells when they form, she is hoping to find ancient DNA inside them. A re-evaluation in consideration of the empirical Evidence. Laguna La Yeguada, strategically located near the archaeological sites that formed the basis of her phytolith work, provided a fruitful place to look for evidence of past climate change and human impacts on the vegetation.
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.

Starch fossils and the domestication and dispersal of chili peppers Capsicum spp. Location Fairfax, Virginia, United States. The artefacts also contain maize starch Zea mays L.
Views Read Edit View history. Investigating the Cradle of Maize For the pipreno 7 years, Piperno and her team have tackled the long-debated question of where and when maize was domesticated.
This project will also involve large expansions dolroes the Amazonian modern phytolith reference collection doloress that the numerous currently unknown phytoliths being retrieved from the ancient soils can be identified and employed to reconstruct prehistoric forest management of various types. This date for maize cultivation is colores than 2, years earlier than any previously reported from the Amazon basin2. How can plant microfossils be improved as a discovery tool for paleobotanical history?
Piperno’s work connects two passions she has had since childhood. These plants did not produce identifiable phytoliths and could not easily be traced through their pollen. Another main focus of current investigation is the impact and legacies of prehistoric human modification on Amazonian forests through phytolith and charcoal studies of terrestrial soils from underneath standing interfluvial and riverine forests in remote areas of the Amazon Basin.

Profile of Dolores R. Piperno
Paleoecological data from two sites in central Pacific Panama have allowed the reconstruction of Late Pleistocene climate and vegetation in lowland areas, the timing of dolodes environmental changes, and the generation of predictions concerning Paleoindian settlement and subsistence. Piperno, elected to the National Academy of Sciences insolved that dilemma by pioneering the use of different kinds of plant fossils. A primary interest is the origins of agriculture worldwide and an associated current project involves the investigation of teosinte wild maize and maize growth and phenotypic developmental plasticity in the atmospheric CO2 and temperature conditions in which they were first collected by human populations and cultivated.
Patterns, Process, and New Developments. New citations to this author. Published online Jul She will present archaeological evidence on early agriculture from sites near the lakes in a forthcoming paper. Their combined citations are counted only for the first article.
