The beginning of the Late Neolithic Period about 2200 BC is characterized by the appearance of the Corded Ware culture, pottery with corded decoration and well-polished stone axes (s.c. boat-shape axes). Evidence of agriculture is provided by charred grain of wheat on the wall of a corded-ware vessel found in Iru settlement. Osteological analysis show an attempt was made to domesticate the wild boar.[6]
