Dogs Evolved to Eat Your Leftovers

Humans did not just tame dogs; we fundamentally rewired their biology. Thanks to thousands of years of shared meals, dogs evolved the unique ability to digest starch, a feat most wild wolves cannot perform.

Long before we settled into farming, hunter-gatherers were already changing the genetic makeup of their canine companions. Because dogs lived closely with humans, they developed special enzymes to process the grains and starches found in our food scraps. This dietary adaptation helped them thrive alongside us while their wolf cousins remained strictly carnivores. It is a perfect example of how our two species physically changed together over millennia.
