I think splenda is a good example, in the end after killing thousands of animals to approve it people discovered it can actually cause weight gain[1]! Kind of destroys the original reason for it. That's the thing with models, they're just models and ultimately they will have flaws. We rely heavily on animal testing and have built up reasoning to say why it's right, and that it helps, but we also don't know how much it hurts our own science with ridiculous blunders like that. Another recen inflammation, and they've been used for decades![2] That being said, do I think science would progress slower without animal testing, or just far less and safer for the animal testing? Sure, probably, but it's worth the cost, and we'll get some benefits with less horrible blunders by relying on models. Another example, science could progress a lot faster if got rid of safety laws to test on humans, but somethings are just wrong so we don't do it.
