Scientists say dogs evolved over 7,000 years to better be our best buds

---Researchers compared the DNA of ancient dog and wolf bones with that of modern pups and found that the loyal canines had evolved over the course of 7,000 years to better digest the food humans ate…found that ancient dogs began developing a higher number of special genes that helped them digest starch, found in wheat and millet. "This expansion reflects a local adaptation that allowed dogs to thrive on a starch rich diet, especially within early farming societies, and suggests a biocultural coevolution of dog genes and human culture," scientists wrote in the study.
