Depending on the day that you visit EPCOT, The Wonders of Life Pavilion may not be opened. The last 2 times my family vacationed in Orlando, we were unable to enjoy this exhibit so I am hesitant to write much about it. Evidently, the pavilion is only open during particularly busy times or perhaps when other pavilions are closed for renovation.
I also suspect that the pavilion is used for more corporate events where a visiting company or association will rent out the pavilion for an evening after the park has closed.
