Man's best friend - a scientific basis?

[Catherine]

Thank-you for finding the articles. This is really interesting and it does have some interesting implications. We clearly have given some of our DNA to dogs over the centuries of sharing life together. Do we in return have some dog DNA? We already know that we have Neanderthal DNA mixed in with ours. What else do we have?

Does this mean that any two species that are closely associated, start sharing DNA? That blurs the line between species a little. It all bears further study and further thought.
