Ancient farming clues may finally expose where humanity's most important wheat first emerged

The exact origin of bread wheat (Triticum aestivum) is still a mystery, but researchers believe they are edging closer to the source of one of the most important food staples worldwide. Using genetic studies and ancient plant remains, an international team of scientists has narrowed the location and timeline to the Neolithic period(around 8,000 years ago) in Georgia, in the South Caucasus. They present their findings in a paper published in the journal Proceedings of the National Academy of Sciences.
