Neolithic use of polished or ground stone tools, in contrast to the flaked stone tools used during the Paleolithic era. Neolithic people were skilled farmers, manufacturing a range of tools necessary for the tending, harvesting and processing of crops (such as sickle blades and grinding stones) and food production (e.g. pottery, bone implements). They were also skilled manufacturers of a range of other types of stone tools and ornaments, including projectile points, beads, and statuettes. But what allowed forest clearance on a large scale was the polished stone axe above all other tools. Together with the adze, fashioning wood for shelter,
Neolithic Europe for many centuries, with ongoing gradual admixture throughout the 5th to 4th millennia BC (rather than a single admixture event on initial contact). Admixture rates varied geographically; in the late Neolithic, WHG ancestry in farmers in Hungary was at around 10%, in Germany around 25% and in Iberia as high as 50%. There is no direct evidence of the languages spoken in the Neolithic. Some proponents of paleolinguistics attempt to extend the methods of historical linguistics to the Stone Age, but this has little academic support. Criticising scenarios which envision for the Neolithic only a small number of language families
