>>I believe that there is at least one intestinal micro-organism << there's >400 microbiota in the human intestinary tract (close to the exit...) where they help us resorb water and minerals, deal with metals (heavy, poisonous etc) and otherwise keep us on our trajectory. getting this system out of balance means for instance cholera, colon cancer etc etc. The first real check of this flora and fauna was made by NASA for Apollo (using "no-limits"- kind of financing). Im part to another try (europe-wide project) using genetic fingerprinting (ribosomal S16 marking of these beasts).

Symbiotic microbes of choice, well established a couple of Myears in every one of our cells, are mitochondria - but they will travel with us wherever we go.

I was using a very low threshold for "viable" - able to live outside the mother's womb for a day would meet the definition. Growing a human fetus in utero (mechanical or otherwise) for 9 months is quite an accomplishment. I don't suppose you've ever done it yourself, but I have. The person who comes out isn't any different from the person was in there stretching and kicking, tossing and turning all day and all night for what seems like years. From my perspective, the main differences were getting to see the face of what felt like an octopus, feeding in a different way, and carrying in a more convenient manner.

Do we really need all the bacteria, yeasts, mites and whatnot that freeload on us? As DJ said, the beneficial ones keep the harmful ones in check. In a completely sterile environment, there would be no harmful ones, either.

"Human" to me means human culture. But children are very adaptable. They'll love a robot if it feeds them, changes its diapers and sings it a lullaby.

Along those lines (probiotics that might be missing) a substantial amount of our initial immunity is passed from mother to child via the placenta. I think. I'm not an expert on biology. Further, Iron is passed from generation to generation.

I suppose the answer to the non-probiotic issues is the supporting media during the maturation process. I expect we will know by the end of this century.
