I hope you are right - but I think our genetic makeup strongly shapes our
environment - much more so than most people think - it is no accident that a
mole lives in a hole.

Natural selection greatly strengthens your argument - but what about
unnatural selection? Ah, but that's another subject. Can you give examples
of systems that become more complex on their own other than life? I digress
again. Once again, I don't think the new unexpected characteristics you
talk about are that unexpected.

This is a very interesting point you have brought up here. I said the same
thing many years ago about the so called large amount of "nonsense" coding
in the DNA molecule. I believe, as you point out, that much of this
"nonsense" is old genetic information - and in fact, contains evolutionary
vestiges of our past. I think a man named Albert Szent-Gyorgi had some
interesting insights as to some of the problems of this genetic "junk".

How much $$$ ?

I found your argument to be very well put.

I am all for research - and I hope you are right - but I still feel genetics
seems to get all the attention - whatever happened to physical chemistry? I
think Otto Warburg had more insight into some disease processes over 60
years ago than the sum total of all the genetics researchers to date.

I have heard this same stuff over and over again about cancer. I have not
seen any advances in the treatment of cancer. Oh sure, we are slowly being
forced to admit that the so-called quacks have been right about some things.
A short 10 years ago the "Powers That Be" called anyone a quack who said
that diet had anything to do with cancer. Now I ask you - Who were the
quacks? I have watched many people die of cancer - so don't tell me about
advances in cancer treatment. These people all received the latest and
greatest - and you know where they are today? They are dead.
And if you get cancer - you will get the same mix of chemotherapy and
radiation - oh, they may give you a little more of A than B, or a little
more of C than D, but in the end you will end up where they are. A nice
thing about oncology - the customers don't complain. Sorry if I sound
bitter - too bad!

Like I said, I am all for research. You want proof that genetics research
is not living up to its potential? Here is a quote from a recent national
"However, experts are leery of widespread genetic screening. Among the
--Even if someone is found to have a genetic susceptibility to cancer, it
is not clear what, if anything, can be done to help them avoid the disease.
--A negative test result may give a false sense of security. A woman with
no errors in her BRCA1 gene still probably faces the same 12 percent
lifetime risk of breast cancer that other women have.
--Those who carry the gene might be shunned by insurance companies. "It
is critical that we create safeguards to ensure that the benefits of
testing exceed the risks," Collins wrote in a journal editorial."
I don't know about you - but if I were a woman I would want to know if I had
the BRCA1 gene. I could at least try to avoid the disease. And look at the
reference to the insurance companies. Like I said - if we can't even tell
people when genetic research has a clear benefit - then what good is it?
And to the use of gene-splicing... You know, life evolved over millions of
years to be in its present state. Ancient Chinese proverb says, "Man who is
at war with Nature - is at war with Himself."
