Instead, the study suggests, domesticated cats flourished in China only by following the Silk Road, arriving there around 1,400 years ago. It’s also possible that climate change led to agricultural and population shifts in the region, possibly affecting how much food was available to the lurking Asian wildcats, the researchers suggest.
The paper published in Science, by contrast, focused on Europe and North Africa. It builds on previous work that had suggested the ancestors of domestic cats were a blend of Near Eastern and North African wildcats.
For the new research, the scientists analyzed samples of nuclear DNA—the main genome of an organism, containing both parents’ contributions—from the same specimens that were examined in the older study, which had not looked at this type of DNA.
Particularly intriguing was taking a new look at cats that lived in Turkey thousands of years ago. “I was so excited to have a look at their nuclear genomes for the first time,” says Marco De Martino, a paleogeneticist at the University of Rome Tor Vergata and co-author of the study.
Yet the new analysis suggested something dramatically different to the older work. These Neolithic felines were pure wildcat. The finding, similarly to the results of the analysis done in China, suggests that cat domestication unfolded much more slowly than scientists had thought.
“The cat is a complex species; they are independent,” says Claudio Ottoni, a paleogeneticist at the University of Rome Tor Vergata and another co-author of the Science study. “They were not just staying with humans—they would still go around and mix with local wildcats.”
Both findings suggest truly domesticated cats arose far later than previously believed—perhaps as late as 2,000 years ago. If that timeline is correct, it underscores just how rapidly cats have settled into the human world—and how much we have to learn about our feline friends.
