Actually lab rats do have a connection to humans. Why do you think we do medical tests on them first?
Physiologically speaking, rats, like most monogastric mammals, have a great deal in common with human beings in terms of how they absorb, metabolise and excrete drugs given orally. They have far more in common than they do not have in common
Decades of research of thousands of chemicals has shown that overall, pharmacokinetics and toxicokinetics in rats are highly predictive of pharmacokinetics and toxicokinetics in human beings.
Rats are somewhat less predictive of dermal toxicity in human beings, and rabbits or guinea pigs are often used as the test species instead, because experience has shown that their skin, if the hair is clipped, tends to react more like that of a human being than a rat’s clipped skin does.
They are exothermic, pentadactyl, have four limbs, two eyes a mouth a nose, lungs, liver, kidneys a similar brain architecture but with different size and proportions (infact they have pretty much all the same organs). They give birth to live young and have a placenta, lactate and have nipples. The are Eukaryotic so are very, very similar on the cellular level as are most Eukaryotes.
They have spine and a skull, their nose is arranged above their mouth and they have two eyes very similar in basic construction to human eyes e.g. same sort of lens system made out of the same stuff a retina wired to the brain in the same way.

Hoping for the right answer most are are a dice roll massive over doses hoping for the right answer.
Ever wonder why they ask for human volunteers if you want the true answer it’s only to go no exceptions.
incorrect. Tests conducted on mice reflect how humans will react
Why do they ask for human volunteers? That's at the end of the testing period - first they test in computers, then mice and finally on humans - for the last 1% of the DNA that we don't share with the test animal subjects
