Like Europeans, the study shows the migration and marriage of millions over 500 years

Scientists managed to provide 86 million profiles from a family site to discover 13 million inhabitants, mainly from Europe and North America.

Looking at genetic data, they were able to create a visualization of immigration and life expectancy and discovered exactly when they stopped marrying their cousins, reports “DailyMail”, the Periscope broadcast.

It has long been thought that people in the West stopped married to their relatives in the 19th century, when transportation was better and allowed them to travel at larger distances.

The rebuilt “Brezas show that we are all connected to each other,” said Peter Visscher, a nominal geneticist at Queensland University who was not involved in this study.

This fact is known by the fundamental principles of population history, but what the authors have accomplished is very impressive. ”

For the construction of the family tree, researchers have downloaded 86 million public profiles from Geni.com, a co-operative web site of “MyHerage”.

About 85% of the people in this tree are from the Western world./Periscopi/
