The 9 Most Tested Lab Animals
An anonymous reader writes "Discover Magazine has this odd photo gallery in which they explain why certain animals are used in scientific research. Why are high-tech contact lenses always tried out in rabbits? Why do we study monogamy in prairie voles? Etc. They say of the 9 animals: 'Taken (or stitched) together, they form a kind of laboratory doppelganger for humans.'"
This list is terrible. I'm a molecular biologist, and one glaring omission is C. Elegans , a tiny little worm that is heavily used in fields such as developmental biology and genetics research. Also missing is the zebrafish, which is also really popular for genetics and developmental biology. While I've seen occasional tanks of frogs around the school, I don't think anyone researches caterpillars. I imagine if I told our (quite reputable) immunology department that they should switch to moths, they'd laugh me out of the school. How can the insect immune system be so similar considering they have an open circulatory system?
