History of Tamil Nadu
The ancestor of modern humans (Homo sapiens sapiens) who appeared around 50,000 years ago was more developed and could fabricate thinner flake tools and blade-like tools using a variety of stones. From about 10,000 years ago, humans made still smaller tools called Microlithic tools. The material used by the early humans to make these tools were jasper, agate, flint, quartz, etc. In 1949, researchers found such microliths in Tirunelveli district.
