(PhysOrg.com) -- A new theory based on studies of locations of large landmarks in Britain, such as stone structures, hill forts and earthworks, suggests they were part of a grid used for navigation around 5,000 years ago, which implies people at the time were not as primitive as previously thought.

The theory, put forward by Tom Brooks, a retired marketing executive turned amateur historian, claims landmarks such as Silbury Hill and Stonehenge were part of a navigation network that allowed people to travel long distances without maps.

Analyzing 1,500 sites in southern England and Wales, Brooks found that all the known sites could be connected to at least two others to make isosceles triangles, which have two equal sides. Some of the triangles have sides greater than 100 miles long, and the equal sides are accurate to +/- 110 yards, which Brooks says could not have happened by chance.
