A 2013 genome study at Uppsala University in Sweden found ten genes that help dogs to digest starches. Lab work suggested that changes in three of those genes make dogs better than meat-eating wolves at splitting starches into sugars and then absorbing those sugars. According to geneticist Kerstan Lindblad-Toh, the rise of farming, beginning around 10,000 years ago in the Middle East, led to these digestion adaptations in us and our dogs. “This is a striking sign of parallel evolution,” she says. “It really shows how dogs and humans have evolved together to be able to eat starch.”
Yes, a very important study. It demonstrates the adaptability of life forms and tells us that dogs can use a very flexible diet. People, when told about this, will still object saying “it is not right” to feed them plants based diets. Obviously this is an emotional reaction, not one based on information.
