Origin
Haplogroup JT is descended from the macro-haplogroup R. It is the ancestral clade to the mitochondrial haplogroups J and T.
JT (predominantly J) was found among the ancient Etruscans.[2] The haplogroup has also been found among Iberomaurusian specimens dating from the Epipaleolithic at the Taforalt prehistoric site.[3] One ancient individual carried a haplotype, which correlates with either the JT clade or the haplogroup H subclade H14b1 (1/9; 11%).[4]
