The starchild skull came into the possession of Lloyd Pye in February 1999 , the skull was found around 1930 in a mine tunnel about 100 miles (160 km) southwest of Chihuahua, Mexico, buried alongside a normal human skeleton that was exposed and lying supine on the surface of the tunnel.
Radiocarbon dating results conclude the skull is 900 years old + or - 40 years
In early 2011, a new analysis of the Starchild's DNA produced a startling result. Four fragments of mitochondrial DNA were sequenced, and their total base pair count of 1,583 amounted to 9.5% of the 16,569 base pairs found in every mitochondria of every human alive.
In humans, those 16,569 base pairs have as many as 120 differences between the 33 haplogroups we all belong to. Neanderthal mtDNA contains 200; Denisova, the new prehuman, has 385; chimps have 1,500.
