OBJETIVO(S)

Objetivos: 1.Se pretende documentar la aparición inicial de cultivos en las estrategias de subsistencia de las poblaciones en el Cauca Medio e identificar las especies de plantas que fueron domesticadas en esta región o importadas de Centro u otros sectores de Suramérica. 2. Se focalizará en la recuperación de vestigios obtenidos de instrumentos y sedimentos en sitios arqueológicos ya identificados y excavados por investigadores vinculados al proyecto. Se plantean nuevas excavaciones para toma de muestras. 3. Una prospección será adelantada en el sector de terrazas y colinas aledañas a la llanura aluvial reciente del río Cauca y al interior de los cursos bajos de sus mayores tributarios, buscando localizar sitios que extiendan la historia de la ocupación humana de la región, hasta el Pleistoceno Tardío.

RESUMEN

The goal of this research was to document the early history of cultivation and plant domestication in the Middle Cauca River Valley of Colombia and to examine the timing of the introduction into the region of plants domesticated elsewhere in the American tropics. The location of this region in the northwestern corner of South America is a good place to monitor the dispersal of domesticated plants moving north from other regions in South America and south from Mexico and Central America. Importantly, the Middle Cauca region contained a number of archaeological sites that were occupied during the Early and Middle Holocene (ca 12,500 to 5000 cal years BP) when early cultivation, plant domestication and dispersals occurred. We planned to focus on the recovery of starch grains, phytoliths, pollen and macrobotanical remains in order to identify the plants being utilized through time. That required that we have access to sediment samples and stone tools in contexts confidently dated to the Early and Middle Holocene from sites within our study region. To this end we obtained 36 AMS radiocarbon dates from 11 different sites, bringing the total number of radiocarbon dates for the sites under investigation to 65. The five sites with the longest history of occupation all have between 8 and 15 radiocarbon dates to firmly establish the chronological sequence in each. The dates on preceramic cultural deposits range from 12,574 + 124 years (calibrated) to 4107 + 85 years (calibrated). Starch grains are preserved on the surfaces of stone tools used to prepare plant foods, but not in sediments. Phytoliths (silicified plant cells) are found both on stone tools and in sediments. Pollen is primarily recovered in sediments although some pollen grains are recovered from stone tool surfaces. Over the course of two field seasons we conducted major excavations at La Mikela, Cuba and Invias 3. Throughout the sequence the stone tool assemblages remained remarkably similar. The most characteristic tools are handstones of unmodified river cobbles and boulder bases used for mashing and grinding plant foods. Also occurring throughout the sequence are large bifacially flaked and normally notched hoes/spades made of medium to coarse grained volcanics. The earliest examples have chipped stone bits while later examples have ground and polished bits. They were apparently used for harvesting roots and probably for planting crops as well. The rest of the chipped stone industry is characterized by the haphazard removal of flakes from irregular cores that are then selected for use with little or no purposeful retouch. Most of the primary material is locally available medium to coarse grained volcanics (e.g., andesite, dacite, basalt) and quartz. Small numbers of irregular cores as well as cobble hammerstones are also recovered throughout the preceramic sequence. The project was a collaborative effort by archaeologists, paleoethnobotanists, palynologists, geologists and soil scientists from the United States, England and Colombia. The information provided by this research will contribute to our understanding of the timing and nature of plant domestication and dispersals in the American tropics (Ranere, 2014). 497 palabras
