| It's long been thought that a large percentage of studies on mice can not be replicated in humans because we are such different species but we use mice because it is cheap. http://www.slate.com/articles/health_and_science/the_mouse_t... Some larger animals might be somewhat closer but a.) much more expensive b.) more ethically challenging to kill/drug something more intelligent at the scale at which we do mice An acquaintance of mine did work in medical studies with mice and he quit after a few years because he said one handled the mice so much that he grew attached to them and could not bear to kill them at the end of the trials anymore. On the other hand we eat pigs and octopus and those are pretty smart creatures. |
