Chickens represent by far the most important poultry species, yet the number,
locations, and timings of their domestication have remained controversial for
more than a century. Here we report ancient mitochondrial DNA sequences from the
earliest archaeological chicken bones from China, dating back to ? 10,000 B.P.
The results clearly show that all investigated bones, including the oldest from
the Nanzhuangtou site, are derived from the genus Gallus, rather than any other
related genus, such as Phasianus. Our analyses also suggest that northern China
represents one region of the earliest chicken domestication, possibly dating as
early as 10,000 y B.P. Similar to the evidence from pig domestication, our
results suggest that these early domesticated chickens contributed to the gene
pool of modern chicken populations. Moreover, our results support the idea that
multiple members of the genus Gallus, specifically Gallus gallus and Gallus
sonneratii contributed to the gene pool of the modern domestic chicken. Our
results provide further support for the growing evidence of an early mixed
agricultural complex in northern China.
