In Tamil Nadu, the Neolithic period had its advent around 2500 BCE. Humans of the Neolithic period made their stone tools in finer shapes by grinding and polishing. The Neolithic humans lived mostly on small flat hills or on the foothills in small, more or less permanent settlements but for periodical migration for grazing purposes. They gave the dead proper burials within urns or pits. They were also starting to use copper for making certain tools or weapons.
