Dogs' ability to digest starch may have contributed to their domestication, according to new genetic analysis that also suggests humans who lived off farmed foods went through similar genetic changes. The findings, reported in the journal Nature, also suggests differences in brain development between dogs and wolves that contributed to behavioral changes as dogs became domesticated. "Now we're also trying to take the behavioral side of the story further to try to pinpoint the genes, the individual mutations, to understand exactly how they might have changed the dog brain and dog behavior," said the study's researcher.
