She wouldn't have evolved so far if she had remained under the Caretaker's care because their lives were so controlled and managed, both by the Caretaker's provisions and by their own cultures passivity. However now that they are left to their own devices who knows? Perhaps having lots of choices has a triggering effect on the Ocampan brain. You know how you can exercise your brain through doing math etc.. to develop you thinking capacity. Well the Ocampans under the Caretakers care had pretty much no exercise in thinking, making choices, learning about consequences. I expect more and more of them will developing dramatically now that their environment is no longer protected.
