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 Goddess", was found near Uzunovo, Vidin Province in Bulgaria, which pushes back the Neolithic revolution to 7th millennium BC. Genetic studies since the 2010s have identified the genetic contribution of Neolithic farmers to modern European populations, providing quantitative results relevant to the long-standing "replacement model" vs. "demic diffusion" dispute in archaeology. The component due to Mesolithic European hunter-gatherers and Neolithic farmers expanding from the Near East were called "Western Hunter-Gatherers" (WHG) and "Early European Farmers" (EEF, also "First European Farmers" FEF), respectively, in the seminal 2014 study which first identified the contribution of three main components to modern European lineages
