Daimabad on the Pravara, shows that the Kayatha culture was succeeded by
the Banas, Malwa and Jorwe cultures in turn.
     These cultures exhibit some similarities in subsistence economies, house
form, flaked stone tool kits, the paucity of ground stone axes, and the limited
use of copper (although at Ahar a heavy reliance on copper and evidence of
rice make the Banas culture here somewhat distinct from the rest). The
ceramics however are distinct.
     Thus, it is possible to consider a process of cultural development and
transmission of ideas for about a millennium along the important marshland
of west-central India, which gave access to the productive basins of the
Krishna and Tungabhadra where· settlements of the ‘southern Neolithic’
flourished.
Early Iron Phase
Just as the emergence of settled village life took different forms in different
parts of the country, so also the introduction of iron occurred at different
times in different contexts.
     A survey conducted to examine the evidence from six regions of South
Asia on the antiquity of the use of iron showed that there was no cause to
impute its origins to the immigration of the Aryans. The survey of the
location of iron ores (suitable for smelting with simple techniques)
highlighted their abundance and wide occurrence.
     On the basis of available radiocarbon dates it was suggested that iron
working might have begun in Malwa around 1100 BC. This was based on the
argument that there was continuity between Chalcolithic and Iron Age
material cultures at sites in Malwa, and the dates for the terminal phases of
the Chalcolithic period here were around 1300 BC.
                               USE OF IRON
  It may be pointless to search for the first site or region producing iron, as
  there are too few radiocarbon dates and as there may not, in any case, have
  been one center of origin. But it is fairly clear that within a stretch of a few
  centuries many communities began to use iron.
