Using the concept of bone functional adaptation, this study analyzes femoral and humeral cross-sectional properties of human skeletal materials from Morton Shell Mound on the Louisiana coast. This work helps fill a gap in such analyses in the southern U.S. and contributes to an understanding of the functional adaptation of the human skeleton. Properties were compared to those of other prehistoric Southeastern fisher-hunter-gatherers from Gold Mine, Plash Island, and several Georgia coast sites to assess mobility and activity patterns among inland and coastal groups. Less sexual dimorphism of femoral midshaft shape among coastal Morton and Plash, compared to inland Gold Mine, indicates lower terrestrial logistic mobility. Greater robusticity (not significant) in coastal samples is linked to an expanded subpersiosteum, rather than terrestrial logistic mobility. Both coastal and inland samples exhibit round humeral shape, typical of fisher-hunter-gatherers.

San Jacinto 1, an archaeological site located in the savanna region of the north coast of Colombia, South America, reveals evidence for logistically mobile hunter-gatherers who made pottery and collected and processed plants from 5940 ± 60 BP until 5190 ± 40 BP (6000-5000 BC calibrated dates). The site is discussed in terms of the social and economic context of the early evidence of pottery in the New World. Social activities and aggregation are indicated and tied to the use of logistic mobility strategies within a restricted territoriality in a highly seasonal environment. Lithic technology also points to the intensification of plant processing as an early stage in the continuum leading to a dependency on food production. This is the first time that a special-purpose site of this kind has been reported for the American tropics. / San Jacinto 1, un sitio arqueológico localizado en la región sabanera de la costa norte de Colombia, revela la evidencia de cazadores-recolectores que realizaron trabajos de alfarería y procesaron plantas silvestres desde 5940 ± 60 a.p. hasta 5190 ± 40 a.p. (6000-5000 a.C. en fechados calibrados). El sitio es tratado en términos del contexto social y económico de evidencia temprana de alfarería en el Nuevo Mundo. Las actividades sociales y el conjunto de artefactos arqueológicos están relacionados con el uso de estrategias de movilidad logística dentro de un territorio restringido en un ambiente muy estacional. La tecnología lítica se relaciona con el procesamiento de plantas silvestres recolectadas, algo que representa, al parecer, una etapa temprana en el proceso que llevó a una dependencia de la producción de alimentos. Esta es la primera vez que un sitio con propósitos especiales de este tipo es reportado para los trópicos americanos.
