Description
Haplogroup C1b2 (B477) is the primary paternal lineage associated with the settlement of Sahul (the prehistoric continent comprising Australia and New Guinea). Arising in Southeast Asia or the now-submerged continent of Sundaland, its carriers migrated eastward nearly 50,000 years ago. It serves as the common ancestor to the major lineages of Indigenous Australians and many populations across Melanesia and Polynesia. C1b2 is a critical genetic marker for one of the most significant maritime migrations in human history.
Interesting Fact
C1b2 is the defining paternal lineage of the initial peopling of the Pacific, and its early split into Australian and Oceanian branches mirrors the geographical separation of these regions following the rising of sea levels at the end of the last Ice Age.
