I don't think it makes much sense for us to build earth-like environments in space. It totally negates the benefits of being in a zero-g environment. I think it is more likely that our biology will be forced to adapt to space than the other way around. I can imagine a future where humans live in individual pods while hooked up to virtual reality systems that can simulate all the necessary needs of the person within the pod, while the pod traverses shared space near lagrange points to collect necessary resources. It'd be a sort of "cell" in a larger multi-cellular collective surrounding our local star; much like endosymbiosis lead to mitochondria when eukaryotes first evolved, humans will merge with machines to become space-faring cellular life.
