Failure of Intelligent Design and Evolution. |
All species has some survival mechanism which is consistent with
current physics theories.
But since no animal has developed inertial propulsion, anti-gravity,
FTL, invisibility cloak mechanism, we can conclude that said mechanism
will never be part of physics.
Especially I am curious about invisibility cloak. Biggest survival
tool. How ID/Evolution failed to develope invisibility cloak?

Hi John_Wilkins and Enkidu,
Arm-pit hair isn't long... it just keeps you cool.
Pubic hair is about nerve endings;
it doesn't advertize your long-term health, so it doesn't need to be long.
Long hair on the head is an ad... humans advertize a lot.
Here is what my short, red punky hairstyle is advertising: "Don't like the
way my hair looks? Kiss my butt!"

So, I guess keeping mine short is an advertisement that I live in a place
where the average summer is about seven to eight months long (if it's a normal
year).

What about frizzy hair?
Hair loss and negative hair changes are a sign
of Human Herpesvirus.
The other symptoms/signs are:
-heart disease and atherosclerosis (look up
deposition of plaque in cat cell cultures by
Herpes- also 55% of human plaque has been
shown to contain Herpesvirus).
-arthritic effects in joints
-depression that comes and goes
-those deep bags under the eyes accompanied by
intermittent red swollen spots on each cheekbone point
that leave larger and larger pits.

Hi Neo, White hair is a symbol of authority.
My beard is white, so I might be biased.
Do you know what a SilverBack gorrilla is ? See:
Upload.WikiMedia.ORG/wikipedia/commons/b/bc/Male_silverback_Gorilla.JPG
They're older than 12 years, and have large canines.
In the wild, some of them are 6 foot, 500 pounds.
In captivity, they reach 600 pounds.
Wiki_Pedia says:
Silverbacks are the strong, dominant troop leaders.
Each typically leads a troop of 5 to 30 gorillas and is
the center of the troop's attention, making all the decisions,
mediating conflicts, determining the movements of the group,
leading the others to feeding sites and
taking responsibility for the safety and well-being of the troop.
WikiPedia.ORG/wiki/Gorilla#Behavior
The health of a tribe is heavily effected by it's older members.

Problems with old age can never be selected against naturally, because
they happen after the reproductive years.
Blond is part of the fair skinned Northern European adaptation. Fair
skin contains less melanin, which was a survival factor in places that
didn't get much sun.

Jared Diamond debunked this myth a long time ago in "The Third

Skin colour is a product of sexual selection, not solar protection.
Saharan Arabs are much whiter than tasmanian aboriginals, and have
been in the area quite long enough for any solar protection mechanism
to have evolved in both cases.
Yet it hasn't.
Sexual selection it is, I'm afraid.

Yet Northern Europeand can develop kidney stones in hot sunny climates
because of too much vitamin D production, and children of immigrant
parents from South India and South Africa living in Britain can
develop rickets living in Britain because of vitamin D deficiency, in
spite of what Diamond claims.
Sexual selection it is, I'm afraid.
And also vitamin D production.

No. They produce too much vitamin D(?) if they spend too much time n
the tropics - and children of immigrant parents from host sunny
climates in the UK at least, needed vitamin D supplements because
their standard diet did not peovide enough.

This is a bit garbled. It is true that people with less melanin produce
more of the precursors to vitamin D than darker skinned people (though
not necessarily more of the hormone itself), but they do not produce
"too much" in the tropics. Further, it is an open question why melanism
is associated with latitude. Vitamin D cannot be the whole story (some
Northern peoples are not deficient in melanin -the Inuit, for example),
though it is likely part of the explanation. Sexual selection may also
be an important driver.

The Inuit eat lots of fatty fish, which are a good source of vitamin D.

I don't recall reading that hairs of chimps turn white when they get
old. Why old people's hair turn white? What advantage white hairs give
for survival in old age? What about those blonde, whatever hair for
survival?
Problems with old age can never be selected against naturally, because
they happen after the reproductive years.
Blond is part of the fair skinned Northern European adaptation. Fair
skin contains less melanin, which was a survival factor in places that
didn't get much sun.
This has been exposed as a fallacy.
No. They produce too much vitamin D(?) if they spend too much time n
the tropics - and children of immigrant parents from host sunny
climates in the UK at least, needed vitamin D supplements because
their standard diet did not peovide enough.
This is a bit garbled. It is true that people with less melanin produce
more of the precursors to vitamin D than darker skinned people (though
not necessarily more of the hormone itself), but they do not produce
"too much" in the tropics. Further, it is an open question why melanism
is associated with latitude. Vitamin D cannot be the whole story (some
Northern peoples are not deficient in melanin -the Inuit, for example),
though it is likely part of the explanation. Sexual selection may also
be an important driver.
I believe someone pointed out in a previous discussion of this topic
that the Inuit get plenty of vitamin D from their diet, so melanin isn't
selected against.

For what it's worth, the Inuit get plenty of vitamin D from their diet.
They eat lots of meat, lots of fat, lots of liver and other vitamin-rich
parts of animals. They have to watch out for hypervitaminosis.

Apart from the vitamin D.

survival of the fittest is until reproduction, after that, you are a
dead end and it doesn't matter.

Not quite.
Consider those who are able to enhance their survival by dint of
grand-parents nursing children.
Reproduction by proxy can occur long after menopause.

But hair color, or even existence, has no influence on that.
