Haplogroup JT is a human mitochondrial DNA (mtDNA) haplogroup.

Origin

Haplogroup JT is descended from the macro-haplogroup R. It is the ancestral clade to the mitochondrial haplogroups J and T.

JT was extremely common among the ancient Etruscans.[2] The haplogroup has also been found among Iberomaurusian specimens dating from the Epipaleolithic at the Taforalt prehistoric site.[3]
