A top-10 list indicates 6 primates, cat, dog, and cow. While there has been a lot of testing done on primates and dogs, they are much more sympathetic for animal-rights groups, and the general public, when protesting vivisection, breeding, and confinement.
Anatomically and behaviorally, primates would still be the top choices there. And many, many disciplines experiment on animals, where results don't come at the genetic level.
Good, the genetics match closely. But mice (or rats: see the idiom "lab rat") are also considered vermin, prolific breeders, fit in your hand, short life-cycle, and easily obtained. So they join fruit flies in the lab experiments.
Interestingly, pigs are used in many types of medicine while not enjoying that genetic similarity. In the 1950s and 60s, your insulin and thyroid meds were often derived from pigs.
When the sections are stored above ground, they can make for some really gnarly skate parks. You've heard of the half-pipe, now see the attempts at full-pipe!
I was running Minix and OpenBSD at home, but in 1999 I began using Linux, and that was because it was mature, no longer only a toy for experimenting, but mostly that it was the only PC Unix OS that supported the "ftape" Floppy-Tape interface for a QIC backup drive.
An LLM citing sources is linking you to stuff that it recently found that kind-of matches its answers. I don't believe it is possible for an LLM to cite original training materials, and it wouldn't be desirable if those are unavailable to the end-user, anyway.
This is an added nuisance for webmasters beyond automated AI-training scrapers. When users query an LLM like Grok or Gemini, it will go search a list of websites and "browse" them to glean information, and though that seems like a contradiction to what I just wrote, it is not "LLM" activity, not really "agentic", but sort of a smart proxy.
