I believe that larger YDNA signatures (R, I, J, etc) in general occur
more than once over certain areas.
This is not the conventional explanation which relates all such
changes to solitary ancestors.
In the case of r1b1c7 however the evidence does seem to support the
idea of a single ancestor
or at the least a group of people who were in the same area at the
same time and subject to the same environmental influence.

In lieu of an alternative explanation we may all assume that r1b1c7
derives from a single ancestor.
