One of the more recent archeological ideas is that the Vedic culture is evidenced by Painted Grey Ware pottery in north India, which appears to date around 1000 BC and was found in the same region between the Ganges and Yamuna as later Vedic culture is related to.
It is thought to be an inferior grade of pottery and to be associated with the use of iron that the Vedas are thought to mention. However, it is associated with a pig and rice culture, not the cow and barley culture of the Vedas. Moreover it is now found to be an organic development of indigenous pottery, not an introduction of invaders.
