Stone Age. The Neolithic era follows the terminal Holocene Epipalaeolithic periods, beginning with the rise of farming, which produced the "Neolithic Revolution" and ending when metal tools became widespread in the Copper Age (chalcolithic) or Bronze Age or developing directly into the Iron Age, depending on geographical region. At the Khao Toh Chong rockshelter in Krabi archaeologists have found evidence of a change in diet leading up to domestication due to changes in sea levels. Recent archaeological excavations suggests that domesticated rice was introduced to central Thailand by immigrating rice farming societies about 4000 B.P. Domestication Neolithic culture appeared in many parts of Thailand, Mae Hong Son, Kanchanaburi, Nakhon Ratchasima, Ubon Ratchathani about 9000 BCE. People pioneered wild cereal use, which then evolved into true farming. For peninsular Thailand evidence of rice agriculture exists from 2500 - 2200 B.P. However, the possibility of an early presence of rice agriculture in southern-peninsular Thailand has recently been discussed by scholars Early Neolithic farming was limited to a narrow range of crops, both wild and domesticated, which included betel, bean, pea, nut, pepper, cucumber and domesticated cattle and pigs. The establishment of permanently or seasonally inhabited settlements, and the use of pottery. In Southeast Asia, the independent domestication events led to their own regionally-distinctive Neolithic cultures which arose completely independent of those in other parts of the world. Neolithic settlements in Thailand Spirit Cave Spirit Cave () is an archaeological site in Pang Mapha District, Mae Hong Son Province, northwestern Thailand. It was occupied from 9000 to 5500 BCE by Hoabinhian hunter-gatherers from North Vietnam. The site is at an elevation of 650 m. above sea level on a hillside overlooking the Salween River. Lang Kamnan Cave Lang Kamnan Cave () is an archaeological site in Muang District, Kanchanaburi Province, and is on a limestone upland, facing northeast and 110 m above sea level. The cave is about 4 km from the Khwae Noi River. By analysing the faunal remains in the cave, the cave is believed to be one of the many temporary camps of the seasonally mobile hunter-gatherers. It was occupied from Late Pleistocene to Early Holocene. Wang Bhodi Wang Bhodi () is an archaeological site in Sai Yok District, Kanchanaburi Province, western Thailand. Dating from 4500 to 3000 BCE. Since World War II, many stone tools have been found in the caves and along the rivers in this region. Ban
