Most populations of free-ranging Pan troglodytes across Africa use tools. This is equally true of wild and released populations and of all three geographical races. No patterns of tool-use are universal, although most function to facilitate subsistence. Even in preying on termites (Macrotermitinae, especially Macrotermes spp.) a variety of tools techniques are shown. Regional differences exist, such as nut-cracking with hammer-and-anvil being confined to the far western sub-species. -from Author
