there's a different story like this every few years. what it seems like is that the stones have multiple origin points.

these megaliths are all over the place, and one wonders if that is generally true, and maybe provides fresh evidence for the hypothesis that the purpose of the monuments was as a meeting point. if there were multiple origin points, it could be that there were multiple groups involved in making the monuments, and they could recognize a place where related clans came together for celebration or trade, or even be treaty or territorial markers.

let's take a step back.

most people probably don't realize that stonehenge is merely one example of a type of very ancient building structure that seems to have originated with the neolithic revolution and spread with farming from modern turkey across europe. a wide variety of evidence suggests that a caucasian, but not indo-european, people migrated into europe many thousands of years before the kurgan invasion brought the existing languages and r1* genotypes into the region. these people would have held out on britain longer than anywhere else, but the functions of the megaliths they built on the island are foreign in origin and purpose.

if it could be established that the stones came from many places, it could provide for a loose model as to how different communities in this farming culture, which spread over the entire area that caucasians are indigenous to today, carried out certain relations with each other.
