The ancestors of the people who built Stonehenge travelled west across the Mediterranean before reaching Britain, a study has shown.Researchers in London compared DNA extracted from Neolithic human remains found in Britain with that of people alive at the same time in Europe.The Neolithic inhabitants appear to have travelled from Anatolia (modern Turkey) to Iberia before winding their way north.They reached Britain in about 4,000BC. Details have been published in the journal Nature Ecology & Evolution.

The migration to Britain was just one part of a general, massive expansion of people out of Anatolia in 6,000BC that introduced farming to Europe.
Before that, Europe was populated by small, travelling groups which hunted animals and gathered wild plants and shellfish.
One group of early farmers followed the river Danube up into Central Europe, but another group travelled west across the Mediterranean.
DNA reveals that Neolithic Britons were largely descended from groups who took the Mediterranean route, either hugging the coast or hopping from island-to-island on boats.
