Rabbit history (and a bit about rats, too)

Ed Yong writes about the great confusion over how rabbits became domesticated.   Apparently, there have been a few science-y urban myths floating around about this for some time (not that I had heard of them before.)  But I also learnt some things about how rabbits have been used:

Archaeological evidence tells us that people in Spain and France were eating rabbits as early as the Epipaleolithic period, between 20,000 and 10,500 years ago. During the Middle Ages, they became a high-status food and people started carrying them across Europe. But it’s hard to pinpoint exactly when this happened because of, as Irving-Pease and Larson note, “the intrusion of rabbits into archaeological stratigraphies.” Translation: It’s hard to know if a rabbit bone came from an ancient rabbit, or a recent one that went digging...

....Rabbits are among the most recently tamed animals, and yet neither history nor archaeology nor genetics can accurately pinpoint when they were domesticated. “There is solid genetic evidence that domestic rabbits are closely related to wild rabbits from France, from which they were mostly derived,” says Miguel Carneiro from CIBIO, who recently did his own genetic study of rabbits. “But the timing, initial motivation, and the underlying process remain poorly understood.”

Larson thinks that’s because people tend to wrongly picture domestication as a singular event. “Everything’s the same, and everything’s the same, and something changes like a bolt from the blue, and now everything’s different,” says Larson. “A lot of our narrative structures hinge on that. But if you’re looking for a moment of domestication, you’ll never find it. It’ll recede from your fingertips.”

Domestication is a continuum, not a moment. Humans hunted rabbits, tens of thousands of years ago. They transported the wild animals around the Mediterranean. The Romans kept them as livestock in structures called leporaria. Medieval Britons kept them in “pillow mounds”—raised lumps of soil that acted as earthen hutches. Later, they used actual hutches. Eventually, we bred them as pets. None of these activities represents the moment when rabbits hopped over the domestication threshold. But collectively, they show how wild bunnies turned into tame ones.
Yong says domestication of animals is hardly ever deliberate, anyway:
The problem is that there’s no solid evidence that humans domesticated anything deliberately (with the possible exception of tame foxes that were bred for scientific purposes). There’s no unequivocal case where humans grabbed a wild animal with the express intent of domesticating it. Instead, for example, it’s likely that scavenging wolves were attracted to human hunts or refuse piles, eventually developing a more tolerant attitude that led to their transformation into dogs. Similarly, mice were attracted to our grain stores, and cats were attracted to the mice. “There is no why to domestication,” says Larson. “That implies a directedness that appears not to exist.”
 I wonder, however, if Yong is overlooking the matter of Jack Black, rat catcher to the Queen, who is credited with taming wild rats into pet fancy rats.   Maybe Yong doesn't consider that pet rats are truly domesticated, but there is perhaps a debate to be had about that.  From a book "Domesticated:  Evolution in a Man-Made World":
