Let me ask you something Mike. What perspective do you want to present?
The number of different cellular types is certainly a measure of
complexity. But if the perspective is as you seem to desire, one that says
"no evidence whatsoever for evolution will be allowed into my
consciousness", then your perspective will certainly never see any evidence.

years

Let me describe the computer models the authors created. They had 2000
different 'beings' each of which could go up or down in the number of cell
types with every iteration of the computer. While the maximum number of
cellular types continued to go up, the average species didn't go up in
cellular types very rapidly. Secondly, if the arthropods and sponges had
increased their cell nubmers then they would not be arthropods or sponges.
Populations of fish that did evolve are now called amphibians, reptiles,
birds, mammals etc.
If you want to examine the math of this phenomenon, here is a basic program
I wrote to mimick what the authors of that paper did.
