I am not sure if this is entirely correct, but first I am going to say that life on Earth mostly thrives in the visible range of the electromagnetic spectrum, and perhaps some infrared and ultraviolet (for some creatures), because it is the frequency range that they were the most exposed to throughout the evolutionary timeline.
In the case that early lifeforms on the Earth were given more exposure to highly ionizing radiation such as xrays or gamma rays, could it have been possible to have lifeforms evolve to these frequencies? From a purely probabilistic viewpoint, life would have indeed evolved to adapt to any environmental situations. But from a physics point of view, wouldn't ionizing radiation destroy the genetic makeup of such a species, including the genetic instructions to protect it from the radiation itself?
On that note, are there any cellular level 'shielding' methods that an organism can make use of when living in such conditions? I was once told about a subterranean bacterium species that lives in areas of high radiation from the ground. And then there are the organisms on the ISS that have evolved to withstand the sun's direct rays...
