Resumen
Descripción general del contenido del recurso.
During morphogenesis and as a result of developmental homeostasis, anatomical pair units in bilaterally symmetrical organisms reach similar -but not completely identical- size and shape dimensions. The difference between these units is distributed as a random variable commonly known as bilateral asymmetry (BA). It is considered to be caused by the effect of located factors, mainly environmental, that act during the growth of the individuals and can be used as a measurement of developmental stability. The aim of this work was to evaluate this feature in a group of fishermen of the late archaic period exhumed at Punta de Teatinos in the Semi-arid North of Chile (4905 100 AP - 4000 95 AP). Because of the quality of available information obtained by one of the authors (SQ) this study was made possible. The distributions of cranial and post-cranial traits were analyzed in a simple way and completed with a short exposition on statistical data regarding the decomposition of the phenotypic variation for each feature. Generally the variable distributions were similar to the normal distribution. No sufficient tests could be obtained to show significant bilateral differences between right and left mean values indicating that a stable development process operated during the life of individuals. Uncommon distributions and extreme values were observed, due to certain disorders in the skull, arms and legs of some individuals, being more frequently in children than in adults. Data were discussed within the framework of available information about the adaptation process to marine resources of this particular group of fishermen.
