Inspired by Brave New World (book) Part 1

What kind of ideology is represented by the motto in the building?

The motto is: Community, Identity, Stability
My guess, is the pretention to build, from a society, a group named community which I define as a group that  work together for a goal and could recognize each other as a sibling, creating with that strong relationships. After the community has been recognized, for them to having a feeling of belonging to the community, and unifying the feeling to a group's definiton for themselves then they get their identity. If they can their identity accepted by foreigners and they do not want to change it continuously, they would get a constant level of their identity and with that level not being modified enormously, the stability is acquired.

Is there such a thing as Natural Selection?

Of course it exist. But we need to specify, actually I must say this concept doesn't apply to the human anymore. Why?
There are many supports for humans to making them survive and don't forget people is not anymore required by nature because people basically stays in cities. With regulations and mass production it's difficult for people to develop their hidden or not often used habilities. Despite this, the majority of newborns are best fitted for the world that has been created than the creators, so the effect of the hand of natural selection is still  slightly visible.
And for animals, there couldn't be more visible the mentioned hand, because, if humans stay away, their world is wild and that demand for the best use of their habilities to survive and reproduce and those habilities are inherited to nexts generations.

If you could decide who to reproduce/clone, who would you pick?
This is an incredibly hard question, I've been thinking on how to pick the ones with rights to reproduce, I haven't time to think about cloning.
Taking away the right to reproduce implies to remove the caracteristic of being a living being from that people. Very different than allow them to try and not getting it.
Besides, who can assure we aren't the best option that is allowed for us on our time? We have on our shoulders so many things, mainly knowledge, that if we had chosen to not live the disgraceful things, we wouldn't have the option to solve it.
And about cloning people, maybe the most intelligent people, not only about science, and people with natural defenses against diseases could be a good option.
