Origin

Haplogroup J has an estimated age of about 45,000 years. In his popular book The Seven Daughters of Eve, Bryan Sykes named the originator of this mtDNA haplogroup Jasmine.

Subgroup J2a1a originated about 11,000 years ago perhaps in Spain. It spread into Europe after the last Ice Age.

Distribution

Haplogroup J (along with ‘T’) is associated with the spread of farming and herding in Europe during the Neolithic Era (8,000-10,000 yrs ago).

The average frequency of J Haplogroup as a whole is highest in the Near East (12%) followed by Europe (11%), Caucasus (8%) and North Africa (6%). J2 is localized around the Mediterranean, Greece, Italy / Sardinia and Spain. J2a is has an estimated age of 19,200 years (± 6,900 years). It is homogenously spread in Europe, but is absent elsewhere.
