Are Armenians and Pontic Greeks DNA related
DNA World Map: The Genetic Impact of Historical Events
Did you know that the Tu living in China are related to Greeks? Their DNA shows that around 1200 Europeans of Greek origin mixed with the Chinese population living there at the time. It was probably traders on the Silk Road who carried their genetic material to the remote corners of China.
World history is reflected in our genes. When people from different ethnic groups reproduce, their children's genetic makeup is a mixture of the DNA of both ethnic groups. It has been passed on through generations to this day.
Researchers from the Max Planck Institute, Oxford University and University College London have developed an interactive map of the world that sheds light on the genetic history of 95 different populations from around the world over four millennia. And it shows the genetic effects of historical events.
Mongolian DNA widely used
Around 1200 AD, the Mongol Empire developed into the largest contiguous area of rule in world history. Genghis Khan is still a myth and one of the central figures of our world history. Evidence of his vast empire can be found not only in historical documents and archaeological finds, but also in our genes.
The researchers found the DNA of Mongolian warriors in the genetic makeup of the Pakistani Hazara and six other populations as far as western Turkey. The scientists call their method "Globetrotter". Often they are amazed at how well historical events are reflected there.
"Sometimes we find surprising differences in the sources of mixing in people from neighboring regions," says Garrett Hellenthal of University College London. An example of this can be found in Pakistan. Neighboring ethnic groups there had different DNAs: "Some inherited DNA from sub-Saharan Africa, possibly through the Arab slave trade, others from East Asia and still others from ancient Europe," explains Hellenthal.
Traces of the colonization of America
In total, the research team examined genome data from 1490 people in order to filter out "blocks of DNA" that people from different populations have in common. "Every population has its own genetic range," says Daniel Falush from the Max Planck Institute for Evolutionary Anthropology in Leipzig. "If you were to paint the genomes of Maya living today, you would have to choose a mixed color palette consisting of Spanish, West African and Indian DNA.
This mix was created around 1670, which is consistent with historical records that people from Spain and West Africa settled on the American continents at that time. Although we cannot take DNA samples from groups that have mixed with each other in the past, we can still detect part of their genome within the mixed range of populations living today. "
You can track which genome is to be found where on the interactive map. Take a look at the Finnish genes. You will discover amazing things. (Attention, the map is very busy, so it may take a while for the page to open.)
