Haplogroup J-CTS15
What is Paternal Haplogroup J-CTS15?
Haplogroup J-CTS15, also known as Haplogroup J-M304 (Y Chromosome Consortium long-form label), is a genealogical group of lineages defined by unique genetic markers present on the Y-chromosome. Your paternal haplogroup, or that of your father if you do not have a Y-chromosome, paints a picture of your ancient origins and the migrations of your ancestors. Although your paternal haplogroup reflects just one of your many ancestral lineages, it carries information about that lineage over tens of thousands of years.
Haplogroup J-CTS15 is descended from haplogroup J-M304. Among 23andMe research participants, haplogroup J-CTS15 is commonly found among populations in the United Kingdom, Ireland and Italy.
It's important to note that your haplogroup doesn't define your current ethnic identity; rather, it provides an insight into your deep ancestry on the paternal side.

Haplogroup J-CTS15 is linked to men who spread the Semitic languages
Men carrying the J-M267 lineage took part in many waves of migrations over the millennia, and domesticated animals and plants weren't the only things they carried. They may also have been among the communities that spread the Semitic languages, a diverse group that bloomed from a single proto-Semitic tongue in the Levant nearly 5,750 years ago. These men likely carried branches of both haplogroup J and of the Semitic language family through the Arabian Peninsula to the Horn of Africa. Still later, some J-M267-bearing men re-expanded from the Arabian Peninsula back through the Middle East and across North Africa in migrations associated with the emergence and spread of Islam.
