Dog And Human Genomes Evolved Together

A new study finds that genes for diet, behavior, and disease in dogs and humans have evolved together.

The bond between dogs and humans is ancient and enduring. They snuggle up to us at night, gambol by our side during daily walks, and flop adoringly at our feet when we crash on our couches. But new research shows that the connection runs deeper than you might think. It is embedded in our genes.

Researchers from the University of Chicago and several Chinese institutions found that several groups of genes in humans and dogs—including those related to diet and digestion, neurological processes, and diseases—have been evolving in parallel for thousands of years.

This parallel evolution was likely driven by the shared environments of humans and dogs, wrote the authors in a study published May 14 in the journal Nature Communications. [...] National Geographic
