The results: The team found traces of wild grasses and legumes, fruits or berries, green vegetables, and roots and tubers native to the broader region. Shards recovered from sites in the Don River basin showed these people used the seeds of wild legumes (possibly clover) and grasses, as well as showing some evidence of bran and barley.
