Map showing the relative proportions of haplogroups sequenced from archaeologically derived remains.

<p>Each pie represents 100% of the sequences obtained and the numbers inside each pie refer to the legend which details the geographic provenience and the number of samples from each area. Each colour represents one of three distinct haplogroups. The natural range of Red Junglefowl is outlined in red and represents the area in which initial domestication events must have occurred <a href="" target="_blank">[8]</a>, <a href="" target="_blank">[21]</a>. The red shaded area in northern China represents an area in which <i>G. gallus</i> bones have been recovered from archaeological sites older than 5000 BC. This has led to debate about whether the natural range of Red Junglefowl in prehistory extended further north <a href="" target="_blank">[13]</a>, <a href="" target="_blank">[22]</a>, <a href="" target="_blank">[25]</a>.</p>
