The organism goes through many stages

1. Is "the organism" a metaphor referring to the installation piece that is talked about?

2. Does "each one" refer to "many stages"?

3. Would not "adopting" be a more appropriate substitute for "adapting"?

Context:

... a series of works for European outdoor sites in which performers shift breeze blocks to create and continually reconfigure architectural structures. In the twenty-four-hour staging of the work in 1997 the bricks were first arranged to form a high wall. Then the performers entered and began to move the bricks apparently at random, forming new constructions as they went on. Sometimes they operated individually, at other times they collaborated, all the while demolishing and rebuilding... ‘I think nature is interesting enough,’ writes Maynard Smith:
"Art is about human beings, which includes their response to nature. For an artist our response to the notions of randomness, uncertainty, chaos, catastrophe are more interesting than the phenomena themselves…These performances have more of a relationship with developmental biology. The organism goes through many stages before becoming mature, each one adapting and building on the structures which existed before. In the breeze-block pieces information is released into the building process at controlled points in relation to feedback from the process. The information is in the performers’ brains. I think the thing it proves is that the higher the level of organisation, the more evolved and interesting the design."
