Haplogroup I-M170
What is Paternal Haplogroup I-M170?
Haplogroup I-M170 is a group of Y-chromosome lineages defined by unique genetic markers. Your paternal haplogroup, or that of your father if you do not have a Y-chromosome, sheds light on 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 I-M170 is descended from haplogroup IJ-M429. Among 23andMe research participants, haplogroup I-M170 is commonly found among populations in the United Kingdom.
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 I-M170 is linked to the people of Doggerland
One of the places that was repopulated as the Ice Age waned no longer exists. During the Ice Age and for some time afterward, lower sea levels exposed much of the area that is now covered by the North Sea. Known as "Doggerland," the region must have been occupied by men bearing haplogroup I, because today it is abundant in all of the countries surrounding the North Sea.As the meltwaters of the retreating Ice Age glaciers caused sea levels to rise, the low-lying forests and wetlands of Doggerland gradually became inundated. Doggerland's inhabitants retreated to the higher ground that is now the North Sea coast. I-M170 is especially common today in Scandinavia and is somewhat common in England, Germany and the Netherlands.
