What properties would a world need to allow a highly evolved rapidly adaptive species to develop?

Specifically trying to create an alien species that can survive most environmental stressors and find a way to create an environment that justifies the species developing its characteristics that allows it to do this. I want the species to be a large animal like species with ability to survive extremes in temperature and pressure change, hypoxia or anoxia, extremes in electrical and magnetic fields and rapidly changing weather, low availability of food resources, tolerances of toxins and toxic gases. I was thinking a moon orbiting a gas giant may be appropriate with widely varying but periodic magnetic and gravitational fields and its tilted on its axis more than Earth is therefore creating more variable weather patterns or seasons. Maybe it's tidally locked with cold and hot sides??

If anyone could offer input of any sort then that would be greatly appreciated. Thanks
