The development of agricultural societies made possible by plant and animal domestication was one of the most transformative events in human and ecological history. This is a Profile of a recently elected member of the National Academy of Sciences to accompany the member’s Inaugural Article on page 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.

Piperno continues to enjoy golf and reading history books, along with tending her garden at home. 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.

She and STRI’s Irene Holst analyzed 5, to 7,year-old stone tools from the Aguadulce Shelter and found starch grains that appeared to be from manioc, maize, yams, and arrowroot To fill this gap, Piperno explored a new direction in tropical research called starch grain analysis. A 6, year history of Amazonian maize cultivation more. They have included study of phytoliths, starch grains and pollen at archeological sites in Panama, Mexico, Ecuador, Peru, and Israel.

Science, The results verified the first set of pipenro data, providing evidence for an early dollres of manioc and yams, and corroborated previous phytolith data for maize Forests, however, were widespread in extent and many lowland forest taxa apparently persisted, creating the basis for the rejection of refugial theory as an explanatory model for early human occupation.

Academic Press, San Diego. Plants decay so quickly in the steamy warmth of the tropics that it is often fruitless poperno botanical archaeologists to search the soils there for the fossilized remains of the seeds and roots traditionally used in their work.

InPiperno 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. Log In Sign Up. Correlation of reconstructed environmental setting with Paleoindian site location suggests that Clovis adaptations were fluid and flexible, and utilized a pipeerno variety of vegetation types.

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 pipperno, years ago 5. Email address for updates. Sinceshe has been working in the Central Balsas basin of Mexico to investigate the origins of maize domestication and its environmental and cultural context.

Piperno, elected to the National Academy of Sciences insolved that dilemma by pioneering the use of different kinds of plant fossils.

Piperno also found that using pollen, phytolith, and charcoal data in tandem generated more robust environmental histories. After graduation, she went to work as a research technician dolorss Dr.

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. She has also carried out groundbreaking research on the application of phytoliths, pollen, starch grains, and charcoal in reconstructing the agricultural and environmental history of tropical areas, elucidating topics piperbo as the beginnings of maize domestication, the transition to agriculture in southwest Asia, human behavioral ecology, palaeoecology, and the effects of human activity on biodiversity.

Ecological Monographs 62 2, She compared and contrasted phytolith data with pollen and other records from the sites. 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. To this end, as part of her dissertation work, Piperno developed identification keys from modern specimens and conducted a diachronic analysis of phytoliths from several Panamanian sites, and demonstrated the significant presence of phytoliths in tropical archaeological sediments, thereby making a strong case for their archaeobotanical utility in tropical regions.

Another Surprising Tool By the late s, Piperno felt that she had dllores grip on the early cultivation and dispersals of maize and other seed crops, such as squashes, in Panama and northern South America. This date for maize cultivation is more than 2, years earlier than any previously reported from the Amazon basin2.
