Where do dogs get their Vitamin C from, when they don eat fruits?
This is number 2 in the new Questions you never asked, but now that I mention it, yeah, that’s a good point series. So, although you probably never thought about it, now that I mention it, yeah, that’s a good point. Where do dogs get their vitamin C from? Well, actually, we’re the screwed up ones, not the dogs. You see, almost all animals have a gene for making vitamin C. Humans do not. This is because somewhere along the long and glorious line of evolution of man, this gene became a pseudogene. This means that because of some mutation, the gene didn’t code for the protein that makes vitamin C anymore. So now we have a gene that looks very much like the gene for making vitamin C in our DNA, only ours doesn’t work. Although this is not an evolutionary advantage (obviously someone who makes vitamin C is more likely to survive than someone who needs to import it), somehow the gene was nevertheless removed from the species. Most animals, including dogs and cats, can manufacture vitamin C,
