I submitted an answer via the comments. I meant to add the word "challenges" to it. Challenges are at the heart of the evolution for each. Other great applicable words are disruption, innovation, transformation and reinvention. And, of course, the issue of facing the fear of death -- and how fear can either paralyze or motivate. And eventually, when it's time, accepting death/passing/progression to a new form of life. Also, look at how you can apply business/management terms and concepts, specifically, to each.
