¿Cómo surgió el hombre hace treinta y cinco mil años, después de que su antepasado; el Homo erectus, sobreviviera durante más de un millón de años sin ningún cambio evolutivo? ¿Por qué brotan muchas especies durante breves intervalos de tiempo geologico y luego permanecen practicamente invariables durante millones de años?Los acalore}dos debates que tienen ahora lugar en los circulos evolucionistas giran en torno a la cuestion del cambio evolutivo. Si la nueva teoria evolucionista formulada en este libro es correcta y las especies evolucionan de forma muy rapida y radical en pequeñas poblaciones, entonces tendremos que replantearnos nuestras tesis tradicionales sobre la ascension del hombre y el equilibrio de la naturaleza.Steven M. Stanley, figura destacada en este apasionante debate, narra con fuerza y elocuencia la historia de la teoria evolucionista y sus nuevos y espectaculares desarrollos..Utilizando ejemplos tomados del registro fosil y observaciones de especies vivas que se han formado casi ante nuestros ojos, Stanley ofrece un fascinante relato cientifico e historico. Pero aunque 1as discusiones entre los cientificos causen estragos, una cosa es cierta: Darwin tenia razon en lo referente a la evolucion. Y aquellos que traten de defender la tesis creacionista no encontraran ningun consuelo en las teorias del cambio evolutivo rapido analizadas en este libro.

En ellas se documentaron diversas estructuras de habitacion, entre las que destaca una pequeña cabaña oval completa, con hogar central, donde se recupero valiosa informacion que ha permitido la reconstruccion de los modos de vida de aquellas poblaciones humanas.Junto al estudio arqueologico figuran tambien varios trabajos realizados por diversos especialistas en zooarqueologia, paleobotanica (palinologia), geologia, etc. que han permitido indagar en diversos aspectos de la vida en el Neolitico en este rincon de la geografia norteafricana. Los analisis geologicos muestran que el actual archipielago es de formacion relativamente reciente, y que en el Neolitico formaba parte de un gran tombolo, unido al actual Cabo de Agua.

The present volume was born from the interest to analyse the different modalities of the political strategies used by the dominant groups in Maya societies at different moments of their history. It tries to show the diversity of these socio-political strategies, and uses the case studies analysed in order to approach a theoretical understanding of the issue from a comparative and interdisciplinary perspective._,
