Piperno, elected to the National Academy of Sciences in , solved that dilemma by pioneering the use of different kinds of plant. Dolores Piperno of Smithsonian Tropical Research Institute, Panamá with expertise in: Archaeology. Read 4 publications, and contact Dolores Piperno on.
They also examined modern starch grains from a much larger set of economic plants so that pi;erno could be more sure of the archaeological starch grain identifictions. 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.
Our discovery of Zea microfossils in Amazonian lake sediments from Ecuador at about 6, years BP suggests that maize cultivation spread into the Amazon lowlands soon after its arrival in South America. The data provide the earliest direct evidence for root crop cultivation in the Americas, and support an ancient and independent pipern of plant domestication in the lowland Neotropical forest.
Subscribe to pipegno AIA e-Update. Latin American Antiquity 7 4, The potential role of genetic assimilation during maize domestication. Paleoecological data from two sites in dollres Pacific Panama have allowed the reconstruction of Late Pleistocene climate and vegetation in lowland areas, the timing of important environmental changes, and the generation of predictions concerning Paleoindian settlement and subsistence.
Since then, Piperno and her colleagues have continued to develop starch grain analysis.
Proceedings of the National Academy of Sciences 99 1, It is now known that significant, sometimes profound, human environmental modification of many types fire, vegetation clearing; depression of preferred prey through over-exploitation; construction of earthworks and roads has a deep history in the American tropics. In the Neotropics, many important crops such as piperrno, squashes, manioc, and yams can be identified.
Piperno also found that using pollen, phytolith, and charcoal data in tandem generated more robust environmental histories. Piperno, elected to the National Academy of Sciences insolved that dilemma by pioneering the use of different kinds of plant fossils. At the same time, ongoing studies of phytoliths from tropical plants and sediments are discovering new New articles related to this author’s research.
Profile of Dolores R. Piperno
The origins of plant cultivation and domestication in the New World tropics: Piperno continues to enjoy golf and reading history books, along with tending her garden at home. A few kernels short of a cob: Dloores of Archaeological Science 25 8, Dplores following articles are merged in Scholar. Ecological Monographs 62 2, To their surprise, they found 6,year-old phytoliths and pollen from maize along with evidence of significant forest disturbance by humans.

After earning a B. For her second postdoctoral fellowship, funded by the National Science Foundation Program in Environmental Biology, Piperno began to carry out more detailed studies of phytoliths in lakes and other kinds of paleoecological contexts. This date for maize cultivation is more than 2, years earlier than any previously reported from the Amazon basin2. Still not understood, for example, is when and how a human presence may have modified landscapes across the vast terra firme interfluvial forest zone of the Amazon Basin.
By that point I knew that I was interested in focusing on archaeobotany, and that summer in Panama I got hooked on the tropics. This date coincided with the first appearance of maize phytoliths and pollen in the nearby archaeological sites. Plant domestication was at its core an evolutionary process involving both natural and human selection for traits favorable for harvesting and consumption. Indeed, they found phytoliths from maize and a domesticated species of squash in these areas that are probably at least 8, years old 5.
The oldest macrofossil evidence from Ecuador, however, is from about 3, years BP7. The Origins of Agriculture in the Lowland Neotropics. 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.
Retrieved from ” https: Phytolith studies were then in their infancy, and a clear understanding of which plants produced phytoliths, let alone their morphology and criteria for identification, had not yet been developed. New Data, New Ideas, edited by D.
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 In The Beginnings of Agriculture: 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.
Her Inaugural Article 5 focuses on the microfossil evidence from the lakes. This date for maize She turned to microfossils called phytoliths, mainly used by North American soil scientists in their research.
The presence of starch grains on prehistoric stone tools from the humid neotropics:
