> Thalidomide had no negative effects on non-human animals, but created notoriously deformed children in humans

That's not actually true; it causes birth defects in animals as well. Only limited animal testing was performed before it was approved for use in humans; more extensive animal testing, which did demonstrate birth defects, was performed only after it had been withdrawn due to causing human birth defects.
