Actually, given the fact that resources not on planetary bodies are much
more plentiful and easier to get at than those on said bodies would argue
against settling planets once you were in space....

Umm, well that was a given in the original problem statement. ALL colonies
must be self-sufficient, therefore they are either net producers or at least
non-negative. I'm afraid the concept of trade or commerce is out of the
picture, at least until someone invents a much faster way of getting there.

Well, that kind of goes with being a pioneer and always has. You are
reasoning from a modern western viewpoint, and I am afraid that is all it
is - a single point of view. It is by no means the only one, much less the
correct one. The other ninety percent of the world's women can tell you all
about giving birth to lots of babies and working all the while.

You seem confused on what adapt means. Genetic changes to the basic human
genome constitute adaptation and I would not expect to see much of that,
though I could be wrong. After all, that is also just a viewpoint and not
necessarily the right one... Vaccines and immunizations are not adaptations,
but they will certainly be necessary. If planetary colonization becomes a
question, that is the purpose of the Explorer class. It will take years for
a 700 person crew to fully catalog and identify the biosphere of a planet.
In fact, we have not yet completely done so on our own planet!
In earlier discussions it was put forth that perhaps the best thing to do
was to simply remain in space and exploit the resources of the system and
avoid planetary surfaces altogether, at least those of Earth like planets at
