Wouldn’t a thinner atmosphere accelerate the evolution of life?
A planet with 20 percent Earths atmosphere would have more radiation thus more mutations.

And most mutations are detrimental to the organism.

recent science news " Mass extinction event 2 billion years ago killed 99 percent of life on Earth, study says".
and how was this done, a giant meteor striking the earth? no, the oxygen levels on earth grew over 100-million years, then when the oxygen-producing plants and bacteria ran out of food, they died, and then oxygen levels crashed, killing most of the animals that had come to rely on "oxygen". this was a world-wide extinction event.

No, it would have more cancer and death. Most mutations don't survive.

I think you are in the wrong forum. Biologists are the people to consult about life, it's requirements, evolution and structure.
This is the astronomy and space forum. Nothing to do with biology.

The answer to your question, is 'no'.
Radiation-based mutations have few guarantees
and will not always conclude with viable or acceptable results.

It took Mutations to produce Evolution

mutations arent from radiation, mutations occur randomly within offspring. It might actualy be reverse, the dinosaurs were able to evolve so quickly because there was a dense atmosphere with a lot of oxygen that's how they were able to become so big

possible, but we don't know the mutation rate of alien life. It could be much higher or much lower than DNA based life.
