RESUMEN: En este artículo se presentan datos de almidones que sugieren el uso de plantas por grupos forrajeros que ocuparon el río San Eugenio (Cauca medio) durante la primera mitad del Holoceno medio. Se logró recuperar una gran cantidad de granos de almidón (325) de instrumentos de molienda (manos y placas) procedentes de niveles precerámicos del sitio arqueológico La Pochola. Los datos indican el aprovechamiento de plantas ricas en carbohidratos, entre las que se encuentra una variedad de Phaseolus (silvestre o domesticada), convirtiendo al Cauca medio en una región promisoria para estudiar la domesticación y la expansión de este género. Por último, se propone un modelo de manejo del bosque basado en el uso selectivo de plantas y en el incremento de la diversidad local, que antecedió a la llegada y el uso de plantas domesticadas de origen alóctono.
ABSTRACT: This paper presents starch grain data that suggest plant usage by human foragers that inhabited the San Eugenio River Basin (Middle Cauca) in the fi rst half of the middle Holocene. A large number of starch grains (325) were recovered from grinding tools (manos and bases) from the preceramic levels at La Pochola archaeological site. The data suggest the exploitation of carbohydrate-rich plants, including a variety of Phaseolus (wild or domesticated), making the Middle Cauca region an important place to study the domestication and expansion of this genus. We then propose a forest management model based on the selective use of plants and the increase in local plant diversity that preceded the arrival and use of foreign domesticates.
