Stable isotope analyses demonstrate that [C.sub.4] plants played an important dietary role in Eurasian prehistory. Uncertainty remains, however, about when and how crops were integrated into the diet of Central Asian populations. Here, the authors present [[delta].sup.13]C and [[delta].sup.15]N stable isotope analysis of human and animal bone collagen from Kyrgyzstan, revealing [C.sub.4] plant--likely broomcorn millet--consumption in the third millennium BC. Combining this evidence with AMS radiocarbon dating and animal collagen peptide fingerprinting demonstrates that broomcorn millet was consumed by humans and animals during the earliest episodes of the westward spread of this crop plant. The results contribute to debates about the timing and means by which domesticated millets were dispersed across Eurasia.
