Cattle domestication from wild aurochsen was among the most important innovations during the Neolithic agricultural revolution. The available genetic and archaeological evidence points to at least two major sites of domestication in India and in the Near East, where zebu and the taurine breeds would have emerged independently. Under this hypothesis, all present-day European breeds would be descended from cattle domesticated in the Near East and subsequently spread during the diffusion of herding and farming lifestyles. We present here previously undescribed genetic evidence in contrast with this view, based on mtDNA sequences from five Italian aurochsen dated between 7,000 and 17,000 years B.P. and >1,000 modern cattle from 51 breeds. Our data are compatible with local domestication events in Europe and support at least some levels of introgression from the aurochs in Italy. The distribution of genetic variation in modern cattle suggest also that different south European breeds were affected by introductions from northern Africa. If so, the European cattle may represent a more variable and valuable genetic resource than previously realized, and previous simple hypotheses regarding the domestication process and the diffusion of selected breeds should be revised.domestication ͉ Europe ͉ mtDNA ͉ aurochs

This paper brings to light a depiction of Milan made of small areas connected with the theme of urban agriculture and ‘spaces to care for' within the city. They are projects of different types which have in common the idea of connecting the practice of cultivation with the construction of shared life paths. Thinking which interprets horticulture as a device for ‘cultivating others' is therefore central here. It is a system for social promotion and inclusion, an instrument to practice forms of dissent, a platform for strengthening bonds, a common space for everyday life. In this sense the English community gardens defi nition, which although it places a perhaps excessive emphasis on community aspects, seems apparently more appropriate for referring to this type of experience connected with forms of social participation and a new relationship with the local community.
