Haplogroup W — Safekipedia Discoverer

Haplogroup W is a type of human mitochondrial DNA (mtDNA) haplogroup. Mitochondrial DNA is found in the energy-producing parts of our cells and is passed down from mothers to their children. Haplogroups like W help scientists study how humans have moved and changed over many thousands of years.

Haplogroup W is one of many groups that researchers use to trace ancient human migrations. By looking at patterns in mitochondrial DNA from people around the world, scientists can learn about our shared ancestry and how different populations are connected.

This haplogroup is found in people living in parts of Europe, the Middle East, and other regions. Studying haplogroup W helps give us clues about the history of these areas and the movements of people long ago. It shows how all humans are linked through our genetic heritage.

Origin

Haplogroup W is thought to have started about 23,900 years ago in Western Asia. It comes from an earlier group called haplogroup N2.

Distribution

Projected spatial distribution of haplogroup W.

Haplogroup W is found in Europe, Western Asia, and South Asia, with a high concentration in Northern Pakistan. It has also been identified in the Maghreb among Algerians and in Siberia among Yakuts.

This haplogroup has been observed in ancient times, including among ancient Egyptian mummies from the Abusir el-Meleq site and in individuals from the Starčevo culture and medieval Sungir.

Subclades

Phylogenetic tree of haplogroups I (left) and W (right). Kya in the left scale bar stands for thousand years ago.

This section shows how haplogroup W is divided into smaller groups, called subclades. Each subclade has been found in different parts of the world and in various populations.

The tree shows that haplogroup W splits into two main branches: W1 and W-C194T. From these branches come many smaller subclades, found in places such as Italy, Poland, Finland, Spain, Turkey, India, and many others. Some examples include W1a, found in Finns, and W3a1, found in many places from Armenia to the United States.

Famous members

Some well-known people belong to haplogroup W. Biologist Rudolf Raff was a member of haplogroup W. Journalist and investor Laurel Touby is a member of haplogroup W3a. Businesswoman and television host Martha Stewart belongs to haplogroup W6.
