Read the Bible, haven't read Orgin of the Species.

I have been reading popular science books (Life on Earth... asked for the book for my 7th birthday and enjoyed it very much) on biology and then astronomy as a child. Went on to do a BSc with majors in Physics and Geophysics, have also done first year core units in Chemistry, Astrophysics and Geology and a few electives such as Marine Science.

I would put my level at informed spectator.
