The cells of the sea anemone, a very simple early form in evolution, are as complex as the cells of higher forms. First life, when it appeared, had to be highly complex. Any living cell, even the earliest ones, are now recognized as having to be highly complex.-http://www.nature.com/nature/journal/v455/n7217/full/4551184a.html-And a whole issue of New Scientist suports this emerging concept:-http://www.newscientist.com/special/not_so_simple
