      To many of us, dogs are the most familiar and best-loved of all animals.
      Agricultural worker, companion, pet and even surrogate child are all roles that
      have helped earn domestic dogs the tag "man's best friend". Now, Peter
      Savolainen and his colleagues' phylogenetic analyses have shown that East Asia
      was probably where dogs were first domesticated and therefore where dogs and
      humans have been living together longest. These new data also provide the first
      evidence that the incredible diversity of dogs we see today - think of the
      Chihuahua and the Great Dane - might have originated from a single wolf
      population.

      Mitochondrial variants of the 654 dogs sampled from all over the world fell
      into five evolutionary groups (clades), suggesting that dogs originated from at
      least five female wolf lines. Knowing the geographical sources of the wolf
      haplotypes related to these clades isn't much use in determining where they
      originated - wolves are too mobile - which is why a worldwide survey of dogs
      was required.
