Hi Mike, Xenophile:

Making an analogy with the evolution of life in earth dry surface,
when life arrived to the ground was anphibious for a long time.
Frogs, salamanders and similar animals live quite way in water and
in the ground. Nature evolves slowly, step by step.

I bet if some certain genetic fixings are needed to addopt people
better to space, those will be done in a very slow and conservative
manner. For instance, preventing seasickness, making harder for the
organism to lost calcium, and to addopt the brain to 3-D will be the
first steps, slowly, little by little. Perhaps in 100.000 years
humans would have evolved so much we couldn't recognize them, but in
between people more likely won't notice any change at all.

I agree with the idea that boots and other artificial gear will help
people to addopt better and fast. But I think that changed the DNA
couldn't be discarded... at least we start to believe DNA is taboo
and sacred.
