Or, as Dr Malcom would say: life, uh, finds a way.
This should be a crucial piece of information about the tree laws, yet it's not mentioned in the Wikipedia article about the three laws [1], which is otherwise quite detailed.

He wanted an alternative to the Frankenstein plot where robots kill their creators and the three laws were part of the answer.
