Tell us if this better helps your understanding of the movie in the comments below...
Not sure who to send this to. I've seen Prometheus twice now and have discussed it many times. One thing that came up many times was the many mutations that took place and why they were all a little different. So I took to some mind mapping software to try to outline what happened and to better understand things. I'm not sure it's perfect, however, I look forward to this provoking discussion and seeing if there other takes on it, or missing elements.
I think it is safe to say that this DOES contain spoilers!
