A los comienzos de la historia del ser humano se le denomina 'prehistoria' pues el hombre no habia desarrollado aún la forma de escribir y, por tanto, solamente existen hallazgos arqueológicos como testimonio para conocer su más remoto pasado. Durante este largo período de tiempo, que abarca las Edades de Piedra, Bronce y Hierro, las primeras comunidades humanas vivian protegidas en cuevas, se alimentaban de los animales que cazaban y la piel de éstos servia para vestirse, sus herramientas eran de madera y piedra y no existian las ciudades ni grandes construcciones.

There is no evidence that a commercial bay scallop fishery exists anywhere in the northwestern Gulf of Mexico. No data concerning scallop abundance or distribution was found for Alabama, Mississippi, and Louisiana. Texas is the only state west of Florida where bay scallop populations have been documented. These records come from a variety of literature sources and the fisheries-independent data collected by Texas Parks and Wildlife Department (1982–2005). Although common in the diet of prehistoric peoples living on the Texas coast, recent (last ~50 years) bay scallop population densities tend to be low and exhibit “boom–bust” cycles of about 10–15 years. The Laguna Madre, is the only place on the Texas coast where scallops are relatively abundant; this is likely due to extensive seagrasses cover (>70%) and salinities that typically exceed 35 psu. The lack of bay scallop fishery development in the northwestern Gulf of Mexico is probably due to variable but generally low densities of the species combined with a limited amount of suitable (i.e. seagrass

Ressenya del llibre Anténéandertaliens et néandertaliens du bassin méditerranéen occidental européen. L’autora estudia amb tot detall les restes humanes fòssils pre-neandertalianes i neandertalianes del Mediterrani Occidental.
