We analyze the evolution of the geometric proyectiles at the end of the Mesolithic and the beginnings of the Neolithic: this study is carried out region by region with special attention is given to the segments with retouch helwan. It is observed that during the Mesolithic is a shared evolution in the whole of the Iberian Peninsula and, at the same time, a regionalization according to the preferences by some or other types. During the Neolithic it renews the lithic industry, also the geometrics models. Again, there is a peninsular regionalization: affects to the lithic industry and to the other elements of material culture. Complementarily several examples of transfers are known. In this sense, the helwan segments identify the first Neolithic of, at least, the western half of the Ebro basin, the southwestern France and much of the peninsular interior. As a result of the Neolithic transferences, will also be known in the eastern half of the Ebro Basin and on the Mediterranean coast, at the Neolithic advanced times.
