A synthetic history of human land use: Humans began to leave lasting impacts on Earth's surface starting 10,000 to 8000 years ago. Through a synthetic collaboration with archaeologists around the globe, Stephens et al. compiled a comprehensive picture of the trajectory of human land use worldwide during the Holocene (see the Perspective by Roberts). Hunter-gatherers, farmers, and pastoralists transformed the face of Earth earlier and to a greater extent than has been widely appreciated, a transformation that was essentially global by 3000 years before the present.

Genomics of the Iberian Peninsula: Ancient DNA studies have begun to help us understand the genetic history and movements of people across the globe. Focusing on the Iberian Peninsula, Olalde et al. report genome-wide data from 271 ancient individuals from Iberia (see the Perspective by Vander Linden). The findings provide a comprehensive genetic time transect of the region. Linguistics analysis and genetic analysis of archaeological human remains dating from about 7000 years ago to the present elucidate the genetic impact of prehistoric and historic migrations from Europe and North Africa.

En este trabajo presentamos los resultados de los recientes trabajos llevados a cabo en la aldea neolítica de Mas d’Is (Penàguila, Alicante), centrándonos en las estructuras documentadas. La integración de los datos obtenidos en un contexto regional nos permiten plantear algunas reflexiones sobre la Arqueología social de los primeros agricultores, al tiempo que las dataciones radiocarbónicas permiten ir ajustando la cronología de la neolitización del Mediterráneo Occidental, así como el desarrollo de dicho proceso histórico.
