I thought a huge part of the problem is mice are not that similar to humans (lots of things have different effects on mice versus humans) but mice are really easy/cheap to test with compared to larger mammals that are a bit closer to humans. We could be missing a lot by not testing stuff in humans that has zero/deleterious effect in mice.
