I'm building a world that takes place millions of billions of years where humans have settled into terra formed planets and moons of the solar system. I wanted to play around with the transhuman aliens idea since actual aliens don't exist (and maybe not in the real world). With that being said, I know some possibilities like lower gravity planets yielding taller humans and higher gravity ones yielding shorter humans. With the exception of mars, planets close to the sun might have darker skin cook depending on the conditions. But, I wonder how we can end up with more starfish looking humans over the course of a billions years and is it possible?

Every little difference in environmental conditions, down to the microbes present and the exact composition of molecules and elements present in air, dirt and water, would give natural selection an opportunity to take advantage of. Varying levels of background radiation will impact the mutation rate, and the exact level of solar energy available will have a powerful impact on the metabolism of every organism in the biosystem.

Truth is, evolution is so complex you could handwave almost anything.

They would need some way to get food and live, but think about this.

If there are humans on other worlds, wouldn’t there be a whole ecosystem?
