Area of Specialization:
Caribbean and lowland South America, eastern North America, environmental archaeology, paleoethnobotany.
Research Activities and Interests:
I am an archaeologist, paleoethnobotanist, and wood anatomist. My research involves work with preserved plant remains from archaeological and paleontological sites, and is generally directed toward trying to unravel some of the deep history and inter-complexities of the human- environmental relationship. I work primarily with plant macroremains, including wood, seeds, and other organs, and in a variety of preservation states (carbonized, waterlogged, desiccated). I employ these data sets to explore details of ancient environments and past biodiversity, and use that as a basis on which to focus on human use of biotic resources, emphasizing subsistence systems, resource selection and sustainability, and the domestication of plant species, as a general approach to understanding the environmental, demographic, and social impacts of prehistoric and historic subsistence economies, the emergence of an agricultural way of life, and more. I work primarily in Florida and the Caribbean islands where in collaboration with other archaeologists I have identified the presence of ancient cultivars, plants used in ritual or for medicinal purposes, fuel and fiber resources, and more, along with evidence bearing on the sustainability of biotic resource use and economic practices. Cultural and island biogeographic factors have considerable relevance and inform much of my research.
Currently, the primary projects with which I am involved include a series of Florida and Caribbean Indian sites, in collaboration with archaeologists at the University of Alabama, the University of Miami; and with the Departmento Centro Oriental de Arqueología, CISAT, Holguín, Cuba; Leiden University, Netherlands; and University College London.
Recent Field and Lab Work:
Dr. Newsom is involved with several interdisciplinary projects focused on the emergence of social complexity and political-economic dynamics in the Caribbean, especially on Cuba and Puerto Rico, on the one hand, and on the other, Paleoindian and Early Archaic human ecology in the Southeastern, US, especially Florida. These are or have been variously supported by the John D. and Catherine T. MacArthur Foundation, the National Science Foundation, the National Geographic Society, The Heinz Family Foundation, and the Consejo para la Protección del Patrimonio Arqueológico Terrestre de Puerto Rico.
