Genetic engineering of food is getting a lot of attention now.

We have been genetically engineering more than food for a long time, though. I refer to dogs, mans best friend, who has been modified genetically to suit our own needs over the last few hundred years.

Dogs are at least 15,000 years old, according to John Homans, who has written Whats A Dog For?

They evolved from wolves, but we dont know how. Did dogs domesticate themselves, or did humans breed the tamest wolves into dogs? A new theory printed in the New York Review in March argues that wolves became dogs whose bodies were best able to digest the starches that newly agricultural humans left behind in the trash.

One thing is certain: there is tremendous diversity among dogs, more than any other species, the article notes. We sure do love em, treat them like family, look on them fondly, feed them and pamper them like children.
