Ancient DNA samples have given experts an unprecedented view on where the people who built the iconic British monument, came from.

A new DNA study has revealed that the ancestors of people who erected Stonehenge traveled thousands of kilometers from modern-day Turkey to Britain.

According to reports, scientists extracted DNA samples from Neolithic Human remains found in Britain and then compared them to other DNA samples from the same period in Europe.

Experts found that the ancestors of the Stonehenge builders came to Britain around 4,000 BC, around 1,000 years prior to erecting Stonehenge.

Furthermore, experts say that there is conclusive evidence to suggest that these ancient people actually traveled all the way from Anatolia, in modern-day Turkey and made their way across Europe as early as 6,000 BC.

As they ventured out into the unknown, they spread across Europe the practice of farming.

Migrating from Anatolia, ancient farmers traveled through different routes across Europe. Some are thought to have followed the River Danube and made their way towards different parts of Europe. Others traveled in large groups making their way westward, across Europe.

They traveled along the coastline of the continent and visited different islands by boat.

Some of these people are thought to have walked all the way from Anatolia towards Britain.

Before reaching Britain, they also visited Spain and France.

The results of the study have been published in the journal Nature Ecology & Evolution.

The DNA results have revealed that Neolithic Britons largely descend from groups who traveled across the Mediterranean route. The results of the study also showed how minor British groups had traces of ancestry of groups that followed the Danube route as well.

The ancestors of the Stonehenge builders not only traveled across Europe spreading farming throughout the continent.

As they made their way from Turkey towards Spain, Portugal, and eventually Britain, they spread the tradition of building massive stone monuments, erected mostly using megaliths.

Before the arrival of ancient farmers and monument builders from Anatolia, most parts of Europe were inhabited by small groups of hunters and gatherers. These were eventually replaced. DNA results have shown that the hunter-gatherers from Europe did not mix with the people traveling from Anatolia.

In Britain, for example, hunter-gathers were entirely replaced by the new migrants from Anatolia, apart from a group of people from Scotland.
