Hi meekerdb and all,
Perhaps I am missing something. Isn't this a false dilemma ?
Why couldn't evolution and reason exist together ?
For there must be a reason for everything that happens.

I know, that's why I said "macroscopic". It's easy to make if the wheel is
microscopic because nutriments can just diffuse in and waste products diffuse
out; but as parts get bigger the volume increases by the cube of the radius but
the surface area only increases by the square, so when things get big diffusion
just isn't good enough. Evolution never figured out how to do better and make a
wheel large enough to see, but people did.
? explained in a post above why evolution does not select ?eels. An autonomous
living being must be topologically connected, and weels are not. This is a neat
consequence of the need of repairability. No autonomous robot with weels can
work for long time without supoort.. This is explained in detail somewhere
I can imagine a design in which wheels are connected to the circulatory system
just as some vehicles are built with hydraulic motors in their wheels.? Or the
wheels might be separate organisms in a symbiotic relation.? Those are possible
- but it's too hard to get there from here.? So you make the point yourself,
evolution is constrained in ways that rational design is not.

Oh I think if I tried real hard I could figure out how to make a wheel that you
didn't need a electron microscope to see, particularly if you gave me 3.8
billion years to work on the problem. But the task stumped Evolution.
> If there is no weel in natural evolution is because legs are far superior.
Claiming that nature could find no use for a macroscopic part that could move
in 360 degrees, a part like a neck or a shoulder or a wrist or a ball bearing,
is simply not credible. And I have no doubt that a supersonic bird or a
propeller driven whale or a fire breathing lizard or a nuclear powered cow
could successfully fill environmental niches, but making such a thing was just
too hard for random mutation and natural selection to do.

Anthropomorphism is a very useful tool but like any tool it can be misused; not
all anthropomorphisms are unjustified.

Guilty as charged, I'm a big fan of pride and self worship, it may be a bit
dangerous but is sure? beats the hell out of worshiping God.
you at least agree that is dangerous. Beware of all these self-help books. My
theory is that self-steem, like suicide and the white of the eyes are social
adaptations. ?o other animal has the white of the eyes. Thanks to it, other
people can monitor very well your eye movements, so they can detect your lies,
deceptions, but the others can trust you, because you bring them a mechanism
for mind reading. In the overall, the social group fitness is inproved.
Thats why sunglasses make people to look untrusty and menacing!!!
I left ?o you to elaborate the conjecture of why self-steem and suicide are
?hese social level adaptation may not be good for each one as individuals, but
are good for the society. No society, no you. Therefore in the middle-long
term, these things are good for you and your descendants.
> evolution works simultaneously with infinite variables
Evolution does not work in the rarefied realm of pure mathematics it works in
the physical world, and as near as we can tell in physics there is not a
infinite number of anything.
Evolution works with the computer of all reality, that is at the same time its
own game scenario. It is massivelly parallel. It has the maximum paralellism
that may be achieved: a computer for each element in the game.
Natural selection only works in the here and now and it only works with
whatever random variations occur.? That's why isolation in a an environmental
niche produces biota well adapted to that niche, but not elsewhere.? And such
niches depend on the isolation.? Once they are open to "all of reality" the
marsupials get displaced by the placentals.
> we NEVER are sure of knowing in FULL the reasons behind an evolutionary
True, but we don't need to know all the reasons to make something better; we
don't know all the factors than caused bone to have the exact composition that
it does, but a human made titanium girder is a hell of a lot stronger than any
> That gives evolutionary design an appearance of mess poor design
It certainly does!
> This is NOT the case.
Baloney. Evolution has no need to be perfect because an organism need not be
perfect, it just needs to be a little better than the competition. Just look at
the cells of the retina of the eye of any vertebrate animal, the blood vessels
that feed those cells and the nerves that communicate with them aren? in the
back of the eye as would be logical but at the front, so light must pass
through them before the light hits the light sensitive cells, this makes vision
less sharp than it would otherwise be and creates a blind spot right in the
middle of the visual field. No amount of spin can turn this dopey mess into a
good design, a human engineer would have to be drunk to come up with a
hodgepodge like that.
I explained that before , in detail, why this is so. This desing is better
?ecause it permits the eye to rotate.
No, what permits the eye to rotate is that all the nerves are gathered into a
bundle and exit the eyeball at one place.? There is nothing in the orientation
of the rods and cones that prevents this arrangement with the nerves behind the
photoreceptors.? It just point out that the squid eye may also be less than
optimum since it could have been arrange to swivel by gathering the nerves into
a localized bundle.? It's just another illustration that evolution doesn't have
to produce the best design, just one that's good enough.
