La aplicación de la computación en Humanidades en la última década se ha consolidado como una disciplina clave para el estudio de los procesos históricos desde numerosas vertientes siendo necesaria la utilización de diferentes softwares y lenguajes para la elaboración de dichas aproximaciones y el posterior tratamiento de los resultados. No obstante, son muchos los trabajos que carecen de transparencia (acceso a los datos y código) por lo que se hace imposible su reproducción por otros equipos de investigación. Por ello, en este documento se realiza una revisión de los trabajos publicados en revistas peninsulares para evaluar el grado de transparencia de la comunidad computacional hispano-lusa. The last decade has seen the consolidation of Computational Archaeology and the Digital Humanities as key disciplines in the multifaceted study of historical processes. In this regard, the use of different software packages or programming languages for data analysis has notably increased among archaeologists. However, in many cases open research protocols are not fully observed (when access to data and code are not always granted), which makes reproducibility impossible for other research groups. The present article reviews the transparency of works published in the most important journals of the Iberian Peninsula, to evaluate the degree of openness within the Iberian research community.

In the present article we use geometric microliths (a specific type of arrowhead) and Approximate Bayesian Computation (ABC) in order to evaluate possible origin points and expansion routes for the Neolithic in the Iberian Peninsula. In order to do so, we divide the Iberian Peninsula in four areas (Ebro river, Catalan shores, Xúquer river and Guadalquivir river) and we sample the geometric microliths existing in the sites with the oldest radiocarbon dates for each zone. On this data, we perform a partial Mantel test with three matrices: geographic distance matrix, cultural distance matrix and chronological distance matrix. After this is done, we simulate a series of partial Mantel tests where we alter the chronological matrix by using an expansion model with randomised origin points, and using the distribution of the observed partial Mantel test’s results as a summary statistic within an Approximate Bayesian Computation-Sequential Monte-Carlo (ABC-SMC) algorithm framework. Our results point clearly to a Neolithic expansion route following the Northern Mediterranean, whilst the Southern Mediterranean route could also find support and should be further discussed. The most probable origin points focus on the Xúquer river area.
