When researchers were first doing laboratory experiments about scurvy prevention, they did a lot of studies on rats and pigeons. These went nowhere. Then they did experiments on guinea pigs and got tons of results. This is because guinea pigs, like humans, can't manufacture their own vitamin C. They (and we) have to get all our vitamin C from our diet. Rats and pigeons, on the other hand, can manufacture their own vitamin C and therefore can't get scurvy.
Source: Radio interview with the author of
A Guinea Pig's History of Biology, a book on the organisms used for scientific research throughout history. They didn't mention the date of these experiments, so I'll have to read the book and find out. I think the radio show was "Calling All Pets" of all things - that's what comes on my radio alarm when I have to get up to go to work early on Saturdays!
