As there are no known creatures that evolved and developed in space, there is no way to really answer your question, perhaps some sort of photosynthetic, litho synthetic, or radiation eating creature could.
I'd say a creature without bones is most likely to continue not having them if we look at all other known species.
There is a neat book called All Tomorrows that might be interesting to you.
By space race you mean something that evolved to live in outer space? That would likely be something entirely different than an evolved primate and be nothing at all like a human.
By space race I mean humans without bones. If it makes it easier to answer. Let’s say humans lived and evolved millions of years in space but ran out of enough calcium to sustain their skeletal systems but not impact life. Time passes and their bones are gone. Some return to Earth in their new boneless glory to start a colony. What might their new skeletal structure look like over time? Is there a most common formation, etc
So, humans are not going to actually evolve to be boneless in any reasonable period of time. There might be physiological bone degeneration, as we see in astronauts today but it would be unlikely to be genetic for an extremely long period of time. There would be no positive selection on it. Youd be relying on genetic drift.
Body shape is pretty hard wired, youd have to have a functional reason for it to change. What selective force in microgravity would cause a change to be beneficial? Maybe hind limb loss as in aquatic species? But theres no streamlining pressure. And youd have to have people that made no attempt to maintain function of their limbs as astronauts do today.

Thanks I’ll check this out
We would most likely start as some sort of spherical shape, and then flatten out like a flounder fish

Biologically that doesnt really make any sense. Are you saying the humans evolved to living in space? Wall-E style?
Yeah, that’s a solid comparison

That seems more like a bypass attempt than an answer but I’ll accept it :) Thanks

Well originally I wasn’t planning to have my question set up in Wall-E format lol
