Description
Haplogroup J1b is a subclade of J1 found primarily in the Near East and at significant frequencies in the Arabian Peninsula, the Levant, and East Africa. It is part of the broader J1 lineage that is associated with the spread of Neolithic farming and herding cultures from the Fertile Crescent. J1b has been found in ancient DNA from the Early Neolithic of the Near East, confirming its presence among the founding farmers of the Neolithic revolution.
Interesting Fact
J1b, along with J1c, is among the mtDNA lineages introduced into Europe by Neolithic farmers migrating from the Near East around 9,000–7,000 BCE. Ancient DNA from early Neolithic sites across Europe consistently reveals elevated frequencies of J haplogroups relative to modern European populations.
