DAVID’s comment: oxygen when plentiful allows evolution, but does not drive it.

dhw: I’m not sure that this is a valid distinction. Plentiful oxygen may trigger innovation by offering new opportunities, just as environmental factors trigger adaptation. In that sense it could be said to allow and to drive evolution.

Allowing and triggering are two very different concepts. Note, you define trigger as offering to interpret your comment. When I pull the trigger on my pistol I'm not offering the bullet, especially if you are standing in the way.
