Re: [asa] How fast do fossils form

Steve gives a strong response to the YEC claim. Being simpler, I would
like to know why Willis doesn't know the difference between a
physiological process and fossilization. Maybe I've demonstrated
fossilization in osteogenesis for a couple of decades and whatever the
reverse is for several decades since. At least osteoporosis is rather
common with aging. But I am more likely to be considered a fossil at my
age than to be thought defossilized.

[Remainder of quote snipped]

This quote illustrates some flawed logic that is used in a number of
Young-Earth Creationist (YEC) arguments. The argument goes something
like this.

1. Authorities say the "Process X" takes a long time to happen. (Process
X may include fossilization rates, cave formation, stalactite growth,
coalification, oil generation, sediment deposition, canyon erosion, salt
concentrations in oceans, cooling of granite plutons (as mentioned in the
AiG news brief last week), and helium concentrations in atmosphere - just
to name a few).
2. Under special conditions it can be documented that "Process X"
sometimes takes only a short time to happen.
3. Therefore "Process X" does not take a long time to happen. ("does not
and cannot require a long time" in the quote above.)
4. Implied conclusion: Long periods of time are not necessary and so the
Earth is young.
5. Another implied conclusion: The authorities are lying to us.

The logic flaw can easily be exposed by inserting a more common process
for "X". How about this one?

1. Authorities say that the human gestation period is about nine months.
2. A lady in a remote part of China reportedly had a full-grown healthy
baby after only six months of pregnancy.
3. Therefore human gestation periods are only six months long.
4. Implied conclusion: My wife's three pregnancies of approximately 9
months each were unnecessarily long and she was faking it for at least 3
months.
5. Another implied conclusion: The Doctor was involved in this
deception.

Needless to say, my wife doesn't appreciate this argument and her Dr.
refuses to speak to me now.

To get back to the original point, the rates of fossilization are
irrelevant with respect to the age of the Earth issue. At best they
would only give us a minimum age - if it only takes 60 years to calcify a
fetus then the Earth must be older than 60 years. Not much argument
there unless you infer this means that the Earth is only about 60 years
old. An analogy that I've used before when addressing the fossilization
rate question is to ask, "How long does it take to get from my house in
Denver to yours in Durango?" The answer, of course, is that it depends
totally upon the means used and the route taken (and also whether Wolf
Creek Pass is closed by snow). The same is true for fossilization. I
developed this analogy further some years ago in another post to the ASA
list. See <http://www.asa3.org/archive/asa/200001/0216.html> for a
previous response to the same fossilization rates argument. Also read
the thread responses by Glenn Morton & Keith Miller.
