An analysis of skulls from than 600 ancient and modern dogs and wolves suggests that much of the diversity seen in present-day dogs emerged thousands of years ago. The analysis, together with a study of ancient dog genomes from central and eastern Eurasia — both published today in Science — offers clues about dogs’ origin story, but still no firm answers as to when, where or why they were first domesticated from wolves.
“Dogs, from very early on in their relationship with humans, are a really important part of human cultures and society,” says Carly Ameen, a bioarchaeologist at the University of Exeter, UK, and co-author of one study.
