Science are humans "grays"?

How would the human body evolve and adapt over time in an enviorment with little to no gravity and with different atmosphere/magnetic energy shield etc.

Our bone structure would surely change, as we would need little to no muscle to function as we do on Earth. Over many generations this would cause us to grow smaller and smaller. If there was a lower content of oxygen in the air, maybe our lungs would need to gain in size, same can be said for the opposite.

Would the pigment in our skin change over time? On earth, where your race evolved also shows in the pigment of your skin so it makes sense if light was different or mosly absent alltogether it would affect the pigment of our skin as well.

If light was different than that of our sun, our eyes would have to adjust as well over time. Possibly growing shapewise differently with the change in surroundings.

Is it possible humans are the same original race as "grays" only they evolved in totally different enviorments.

A few of us that went to school together were drinkng, smokin and talkin theory and we started this topic. I know I have learned a couple things on past science topics here so figured this had to be discussed by some people here in the past and wondered if any input can be added that I can throw in the ring next time we get together.
