After attentive observation of the I values, one can clearly see that the results demonstrate a definitive correlation between the amounts of effective information and the organismal phenotypic complexity defined by biological taxonomy and evolutionary theory. C. pombe has the lowest I value, while human beings have the highest. Nematode, insects, amphioxus, fish, frog, bird falls in between. The I values of eukaryotes range from tens of thousands to hundreds of thousands of bits, which are just one order of magnitude higher than prokaryotes'. These results are also consistent to our intuition about organismal complexity, whilst the number of genes is a poor index here. P. tetraurelia has quite high number of genes 39,642, but is actually a simple single cellular organism with low I value. So the effective information is a much better index of organismal phenotypic complexity.
