It's all in the genes

All domestic dogs are descended from wolves and they were the first animals to be domesticated over 15 000 years ago. While wolves tend to look the same, today’s dog breeds come in a huge variety of shapes and sizes. The genetic origin of this diversity has long puzzled scientists. Recent research of some 3 000 dogs from 143 breeds at Cornell University, USA, has shown that a single gene could explain the size differences between breeds.
