The 5,000-year-old stone circles at Stonehenge in England have now revealed yet another mystery.
Right next to these large blocks of stone, remains of cremated bodies have been found at the structure and this is the cause of the theory that Stonehenge was a monument in honor of the dead.
It has not been known who the remains belonged to, but it has now been revealed after new analyzes by English archaeologists.
220 km journey
The bodies were cremated before the bones were buried, so it is impossible to extract DNA from them for analysis.
Instead, the researchers studied different isotopes of the element strontium.
The composition of these isotopes varies depending on where people start, and it can be compared to a fingerprint of where we have raised the person over the last ten years.
Analysis of the bones showed that 5 of the 25 bodies belonged to people who had probably lived in the Preseli Hills in west Wales, about 220 km from Stonehenge.
The other 15 were found to be from the immediate vicinity. The results show that people have moved to the British Isles in large numbers 5,000 years ago.
