A major West Eurasian Y-chromosome lineage whose subclades expanded widely in prehistory and later periods—often found in Atlantic and Central European contexts today.

A heavily studied subclade under R1b; parent to several major European branches with different regional histories.

A large Atlantic-leaning branch under M269—common in western European contexts alongside many other lineages.

A major M269 branch often concentrated in northern continental Europe—one among many lines present in medieval societies.

A paternal lineage long associated—at the population level—with Scandinavian Iron Age and later expansions; still not proof of “being Viking.”

A diverse southern/eastern European–leaning branch often discussed alongside Slavic and Balkan demographic processes—not reducible to one modern nation.

A widespread Eurasian lineage with strong frequency peaks in eastern and northern Europe depending on subclade.

A lineage most often discussed around the eastern Mediterranean and Near East; present across Europe through many separate historical episodes.

A lineage with deep origins in Africa and many branches across the Mediterranean and southern Europe—each subclade has its own chronology.

The most common European mitochondrial super-haplogroup—signals deep maternal ancestry across many populations, not one ancient tribe.

A frequent subclade under H, often discussed in European prehistory—still one maternal line among all your ancestry.

A Paleolithic survivor lineage in European mtDNA trees—often framed as “ancient European hunter-gatherer” signal in broad-brush stories.

A mitochondrial lineage often discussed in Near Eastern and Mediterranean contexts; present in Europe through many ancient and medieval movements.

A less common European mtDNA branch with Palaeolithic depth—popular literature sometimes over-interpreted it; treat with caution.
