Carb Dogs

Back off!

Recently, scientists published the results of a study on the canine genome. One of the crucial differences between dogs and wolves, it turns out, is that only the dogs can digest carbs. For a very long time, scientists and common sensists have reasoned that the domesticated dog as originally a wolf that followed humans around and fed on their middens or kill sites. A few people, sly as foxes, reasoned that both humans and wolves congregated around kills and carrion, and that the domestication process may have been more commensal than unidirectional. 

But now the genes tell us that the domestic dog can consume carbohydrates to some benefit, whereas los lobos cannot, and we move from an understanding of mutual carnivorism or scavenging to four-leggeds hanging around two-legged gatherers or farmers. [Eventually, I have no doubt, I wil learn of the legend in which farming is just a trick that coyote plays on humans so he can eat for free.] Whether it was people growing grain or digging roots, odds are that this imputes a greater role to women than the meat-eater model would have suggested, since women have long dug the wild roots and tended the gardens while men went off to hunt, or whatever it is they did when game was scarce and beer was not yet been invented.

The dog-carb connection comes as no surprise to me. I have a dog that is healthy, and a huge fan of bread. Serendipitously (or, honed by evolutionarily), the mutt likes her bread stale and hard. She is a huge fan of old bagels, and the photo above is her eating a burnt and aged loaf of soda bread, inedible to humans. In that shot, she is slightly blurred because she senses a threat and is springing into action, she feels like the photographer is coming after her precious lithified loaf. Never have I seen a dog of my acquaintance so viciously protective of something not made of ham. 

So thank you, scientists, for vindicating my non-obese, non-diabetic hound.
