Academic Press, San Diego. Ever-improving analytic methods for retrieving empirical data from archaeological sites, together with advances in genetic, genomic, and experimental research on living crops and their wild ancestors are providing new understandings of, and mechanisms for domestication and early agriculture see discussion under Research Focus.
Profile of Dolores R. Piperno
In recognition of her distinguished record of contributions to the advancement of archaeological science, the Dokores Institute of America is pleased to present the Pomerance Award for Scientific Contributions to Archaeology to Professor Dolores R.
Piperno began her work career as a medical technicianand used her training and experience in this field when she moved into archaeology. Investigating the Cradle of Maize For the past 7 years, Piperno and her team have tackled the long-debated question of where and when maize was domesticated.
By that point I knew that I was interested in focusing on archaeobotany, and that summer in Panama I got hooked on the tropics. Missouri Botanical Garden Press; National Center for Biotechnology InformationU.
Correlation of reconstructed environmental setting with Paleoindian site location suggests that Clovis adaptations were fluid and flexible, and utilized a wide variety of vegetation types. Views Read Edit View history.
Skip to main content. There are, to be sure, problems in interpreting prehistoric plant use and paleoecology which cannot be addressed through phytolith analysis; some of the more important ones are listed.
Patterns, Process, and New Developments. 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. Piperno also found that using pollen, phytolith, and charcoal data in tandem generated more robust environmental histories.
Multi-proxy analyses of pipeeno sediments and terrestrial soils e. 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.
Profile of Dolores R. Piperno
For the dolords 7 years, Piperno and her team have tackled the long-debated question of where and when maize was domesticated. In the next 10 years, Piperno would like to extend the utility of phytoliths, she says.
When and how did humans domesticate plants, and why did agriculture originate? Please help to improve this article by pipeerno more precise citations. InPiperno published the first book on using phytolith analysis for research in archaeology and environmental pipernl The Origins of Agriculture in the Lowland Neotropics.
A 6, year history of Amazonian maize cultivation more. To remedy that, Piperno and her colleagues have been studying lakes and archaeological sites in the region 5.
Piperrno can plant microfossils be improved as a discovery tool for paleobotanical history? A few kernels short of a cob: Neither the admittedly limited archaeological or paleoecological data indicated the presence of pre-Clovis populations in Panama, and we chose to view Clovis as the first human expression on the Isthmus.
Meanwhile, she published a new edition of her phytolith book last year, in which she reviewed the present state of knowledge about piperbo discipline and the growth of the field since 3.
The development of agricultural societies made possible by plant and animal domestication was one of the most transformative events in human and ecological history.
In her doctoral thesis, Piperno showed that phytoliths commonly occurred in diagnostic shapes in many kinds of plants, including important tree and herbaceous flora, and that they were present in high numbers in archaeological sediments. Her work with phytoliths and other microscopic remains shows that even plants in the tropics leave behind telltale signs of their presence thousands of years later.
These plants did not produce identifiable phytoliths and could not easily be traced through their pollen. Suggestions that the likely source of many of these crops, the tropical forest, was an early She compared and contrasted phytolith data with pollen and other records from the sites. 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 the Ice Age approximately 10, years ago 5.
Earth SciencesGeoarchaeologyand History and archaeology. This page was last edited on 25 Novemberat 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. Phylogenetic relationships among domesticated and wild species of Cucurbita Cucurbitaceae inferred from a mitochondrial gene: Her research interests include the study of phytolithsstarch grains, and pollen at archaeological sites near the beginning of the domestication of various crops such as cucurbitsmaize cornand peanuts.
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.
Balter M July 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.
Therefore, although tropical forests contain the richest diversity of useful plants pipperno many major American crops like manioc and sweet potato were obviously tropical, anthropologists did not generally consider tropical forests as a place where ancient agriculture originated.
I learned some valuable lessons and skills during that 5-year period, including the importance of good microscopy work. Proceedings of the National Academy of Sciences 98 4,
