Not All Mammals Vomit -- Or How To Study Emesis In Mice

Journal Of Clinical Investigation
Summary:
If biologists have learned anything over the past decade, it is how similar all mammals are at the genetic level. 95% of the genes found in mice are also found in humans, and we even share a significant amount of genes and genetic circuitries with creatures as different as fruit flies or puffer fish. This might not come as much of a surprise to physiologists who have long used animals to learn about basic mechanisms in organ function that are shared across vertebrates or mammals, but the extent of overlap is still impressive to most.

This might not come as much of a surprise to physiologists who have long used animals to learn about basic mechanisms in organ function that are shared across vertebrates or mammals, but the extent of overlap is still impressive to most. In many areas of biomedical research, rats or mice are the animal model of choice. And while most researchers are aware that mice are not just furry little humans that walk on all fours, some fundamental differences surprise even experts. Among 10 scientists who identify themselves as mouse geneticists, only one was aware that mice (and in fact all rodents) lack a very fundamental behavior: they do not vomit.
