Ancient human DNA is a fascination subject , there are a couple of other examples
Cheddar Man - found in Goughâ€™s Cave in Cheddar Gorge, UK . It is the oldest human skeleton found in the UK , dated back to 7150 BCE.
In 1997 , Bryan Sykes , Oxford University managed to extract the mitochondrial DNA from Cheddar man's teeth (apparently it is in haplogroup U).
Amazingly there managed this DNA was very similar to the DNA of the current residents of Cheddar , with two exact matches and one match with only one mutation (to a history teacher called Adrian Target) , which is pretty amazing
