These processes have evolved in the course of almost four billion year
history of the Earth and did not appear all at once:
Fossil record shows that life in its prokaryote unicellular form
emerged ~3.5 billion years ago (Schopf, J.W. 2006. Fossil evidence of
Archaean life. Philosophical Transactions of the Royal Society B:
Biological Sciences 361: 869-885). A mycoplasma cannot move and has no
cell wall but only a membrane and cannot solve its existencial problem
if the chance would not put inside a living organism; higher bacteria
move and express minimal phototaxis but have no fixed order in the
cytoplasmic structure and cannot learn; their behavior is far from the
adaptive behaviors of eukaryote unicellulars.

They don't seem to have much problem evolving resistance to the antibiotics we have developed using our brains and technologies. It doesn't require a brain to evolve, just some genes in a population.

The paleontological record also shows that about 1 billion years ago
the first unicellular eukaryotes appeared (Cavalier-Smith, T. 2006.
Cell evolution and Earth history: stasis and revolution.
Philosophical Transactions of the Royal Society B: Biological
Sciennces 361: 969-1006). These unicellular organisms show a centrally
positioned nucleus, a strictly determined organization of organelles
which were specialized in digestive, respiratory, excretory,
circulatory and sensory functions. Eukaryote unicellulars perform
complex reproductive behavior and complex adaptive behaviors including
the capability to learn from experience.
The fossil record also shows that multicellular animals appeared half
a billion years ago, not earlier than 575 million years (Aris-Brosou,
S and Yang, Z. 2003. Bayesian models of episodic evolution support a
late precanbrian explosive diversification of the Metazoa. Molecular
Biology and Evolution 20: 1947-1954). These multicellulars have been
sponges or sponge ancestors (Erwin, D. et al. 1997. The Origin of
Animal Body Plan. American Scientist 85: 126-137).

However, sponges were shown to be evolutionarily inert although they
had the same number of cell differentiation (7-10 cell types) with
cnidaria.

Evolutionarily inert? What does that mean? They haven't gone extinct have they? I don't think so. You are deriding bacteria and sponges.

The visible difference is that cnidaria succeeded in
differentiating the nerve cell, which was specialized in computation
that would prove to be so important not only in adaptive behaviors but
also in regulating functions of all the organ systems. Is it mere
chance that differentiation of the nerve cell and nervous system
coincided with the Cambrian explosion?

Why are you so focused on nervous systems? Bacteria and plants lack them and they are doing just fine (channeling an absent Moran here). How does your evolutionary scheme apply to the successes of plant evodevo?

It is obvious that all the great transitions mentioned above required
a long period of time. The temporal sequence of the appearance of the
above forms of life and the gradual appearance of the structural and
functional complexity in the living world speak for a natural
evolution of living systems.

My oak and maple trees would be insulted by your neurocentrism, but they lack the emotional processing capacities. The mold that grows in a house with water damage after a tropical storm or hurricane and causes health problems to humans could care less either. The MRSA bacteria aren't all that worried, nor are the strains of TB wreaking havoc still on people around the world. The many quasi-living viruses that coopt living cells and cause unpleasant or fatal diseases could give a rat's ass about your theories. HIV has no brain, but it sure benefits from the way human brains are geared for sex.

Now to return to the intelligent designer you allude to.

First of all it is a product of pure belief, the belief on which all
religions are based and to introduce it in this discussion is
impossible without rejecting the basic tenets of the scientific method
and the rational thinking. But, for the sake of argument, I will. Did
your "Designer" spend 3 billion years to create to humans an illusion
of evolution of living world for contradicting its own existence? If
it took the "Designer" 2 billion years to design the first eukaryote
cell it is not intelligent, at least not more intelligent than the
people who invented him.


Well you got a good point there.

Still though your neurocentricism is no less a distorting bias than that of genocentrism of many modsynth evolutionists.
