The foetus basically develops in a zero g environment anyway- being suspended in liquid- its on the adult that the major effects would occur.
And I would put my money on the body adapting very well to a reduced gravity environment if it was born into it. I have no proof for this apart from the adaptability of genetics and development.
.... I want us to go to mars. I want us to become an interplanetary species. I want us to travel to the stars, hollow out asteroids, wack nuclear engines on them, and get them up to relativistic speeds.
Because if we don't, what is the point of.... All of this?
Anyway I'm a dreamer, but I'm also a scientist, and I suppose the two go together fairly often.
Being suspended in a liquid and zero-g are not at all the same thing. Gravity still pulls, e.g., you will still feel what is up and down.
Experiments with rats indicate that zero-g is not a good environment to have babies, but also that it is possible. In any case we could just create artificial gravity.
My best hope for humanity is transhuman: to adapt ourselves to our environment. Think the ousters in Hyperion.
