Short summary
Many major food crops, including rice, wheat, maize, rye, barley, oats and millet, are domesticated species of grass. However, because grass pollen all looks highly similar, it has been challenging to track grass domestication using pollen in archaeological samples. Here, we show that we can use the chemical signature of pollen grains to classify different grass species. This approach has the potential to help unravel the spread of domestication and agriculture over the last 10 000 years.
