If this represents a clock, then the numbers or correlations "2 o'clock equals transition from Hadean to Archean". Otherwise, I see how this circular format has any benefit over a linear timeline, besides perhaps being more visible on a small screen. However, it is misleading to have a circular diagram, since 1 million years in the future would be equivalent to 1 million years after the beginning of the earth. Perhaps this should be redesigned to spiral outwards like a nautilus shell. --Ice Ardor (talk) 02:24, 26 June 2008 (UTC)
