New studies of canine genetics shed light on the diversity of dogs and our longstanding, still-evolving relationship to them.

The staggering array of modern dog breeds is typically traced to the Victorian era. But half of all canine variation was in place roughly 10,000 years ago, a new study suggests.

After the H5N1 virus hit the remote island of South Georgia in 2023, more than 50,000 breeding females may have disappeared.

“This is a type of science that has an impact that most people could see in their homes,” said Erin Hecht, a canine researcher at Harvard. “Now there’s just no money.”
