Animal (Medical) Experiments

Well personaly i think that is a hard one to answer i suppose it would really depend on what kind of Animal evolved instead of us to be dominant. In a way No for the simple reason of we are the only living thing on this Planet that lives for knowlage where as every other living thing lives by instincts and survival so i guess if something else evolved dominating over us then we would more likly be on the food chain rather than tested on lol. :)
