A new evolutionary tree of dog breeds has been produced based on DNA sequences from over 100 breeds.
The basenji is closest to the root in this survey. These are interesting dogs that don't bark, but make lots of other noises.
The tree is circular with the root (oldest part) in the center and more derived groups branching off farther from the middle.
A tree structure for dog breeds is not (IMHO) the most accurate way to display this information since some breeds were generated by crosses between other breeds (for example Dobermans). A plot better reflecting this kind of relationship would be a network rather than a tree structure. However, the tree probably just reflects the strongest genetic signals.
