THIS ISSUE:
This past week I read through a pamphlet put out by Jim
Lippard - on some of the flaws found in Fundamentalist beliefs.
(If you haven't read it yet, and would like to, contact Jim here,
on any of several other BBSs around, or send a self-addressed
stamped envelope to Jim Lippard, PO Box 37052, Phoenix, 85069.)
I don't agree with everything in his booklet; however, are
some extremely valid points brought up. This week I'd like to
talk about one such point that has been - and will continue to be
- a controversy. Evolution.
There are bound to be a few users who would prefer to avoid
the topic. And that's fine. It's also why I'm introducing the
topic in this first section (as usual), Those of you who would
prefer to avoid the subject need not go any farther.
EVOLUTION
A few hundred years ago the "science" of alchemy was hitting
a peak. Most people think that the single goal of alchemy was to
turn lead into gold. While that's not such a bad goal, it's an
inaccurate description of alchemy. If that's all it was about,
the church would've never condemned it (or, I doubt that they
would have).
The alchemists were fiddling with other things as well. One
of those things involved something called a "homoculus." The idea
was that a living body was a collection of elements and chemicals
in unknown arrangements - and so was a nonliving body. The
alchemists were searching and trying to find what the difference
was between the two.
To be fair, not very many of those "scientists" (in quotes
because, were they scientists, or weren't they?) were involved in
this search. In several parts of the world, to even be *thinking*
about such things was considered sufficiently criminal to have
the thinker put to death - often by slow torture.
In any case, they didn't succeed (as far as anyone knows).
But apparently they were on the right track. The interest
was revived again in this century. Nobel Prize winning scientists
such as Harold Urey were involved with biochemical studies - the
new and more respected (and more knowledgeable) name for what the
alchemists had tried earlier.
The New Studies
This time the idea was to attempt to discover if life could
have started on our planet spontaneously. (Most of you know the
name Carl Sagan. He was also involved in the early studies while
connected with the University of Indiana.)
What these scientists did first was to concentrate the
elemental parts of early earth in a sterile, test-tube environ
ment. Energy was then added to the closed system. (The basic
elements used were hydrogen, oxygen and nitrogen; with the energy
used, separately and together, being radioactivity, sunlight,
heat and an electric spark [all three of which occur in nature]).
The end result in every experiment was a combination of the
basic elements into increasingly complex molecules. That kind of
chemical reaction was pretty well expected. Chemicals *do* tend
to combine. What was more astonishing yet, however, was that the
combination that resulted was heading towards organic.
As early as 1951 the first organic molecules formed. Two
years later, and working with a more and more concentrated (but
still sterile) solution, the molecules continued to combine and
recombine until no one could deny that they were organic in
nature. By the early 1960s the first nucleic acids formed. For
those of you less familiar with organic chemistry, nucleic acids
are the so-called building blocks of protein - and proteins are
the building blocks of . . . YOU! - and of every other living
thing on earth.
Then later in that same decade, the first prime proteins
formed.
This happened again and again and again. Take those base
elements, add a bit of energy, and organic molecules *will* form
and *will* continue to become more and more complex. Under
heavily controlled conditions, with a man-made reconcentration of
materials again and again and again, it took less than 20 years
to go from the purified gases of hydrogen, oxygen and nitrogen to
a relatively complex protein.
During the 1960s and 1970s the studies continued, but along
other, related lines. Instead of starting with base elements, the
scientists began with already existing simple forms - viruses.
In any case, a virus has a protective coat of protein. Strip
away this coating and the virus seems to degenerate into a
collection of organic chemicals. Specific tests were done that
did strip away that coat, leaving two vials - one with the
internal chemical structure, and one with the external protein.
(This *can* happen in nature if the energy kicked in is violent
enough.) Then the two were recombined. And lo and behold! Quite
naturally and without any help from the scientists, the internal
structure and protein coat recombined to make another complete
virus.
Meanwhile, the other studies continued. Just shy of 1970 the
first virus resulted.
Nobody can prove if a virus is alive or not. At times it
acts like a living thing. Other times it acts more like a
mineral. However, many scientists agree that the virus is the
simplest form of life - a kind of missing link between what we
definitely recognize as living, and what we definitely recognize
as nonliving.
Cloning
On the surface, cloning may not seem to be related to the
discussion above. It is.
To date, cloning has been more or less restricted to little
more than what farmers have been doing for years in combining the
advantageous traits of one plant with another. Despite rumors to
the contrary, at this time the highest lifeform successfully
cloned has been a salamander, with very limited success having
been done with rabbits - mostly in using a female rabbit's womb
as the home of an artificially inseminated egg - not true cloning
at all.
At the same time, cloning is quite similar to artificial
insemination (or natural insemination, for that matter) - a
combination of genetic materials.
The genetic structure of all living things on earth is
remarkable similar. It differs primarily in complexity. Other
than that, your DNA and that of a frog (for example) are very
close to being the same.
In very brief, and oversimplest, form, DNA makes you what
you are. It's kinda like a twisted ladder of chemicals, with each
rung on that ladder sorta-kinda representing a particular
characteristic of the creature (including you). Also keeping
things overly simplified, there are 4 basic chemicals used within
that chain - call them A, B, C and D. A will link only with C and
B will link only with D. Rip the DNA ladder in half and it will
tend to reform in exactly the same original shape and format due
to a given and exclusive chemical recombination.
In this way, the DNA can reproduce and reproduce like crazy,
making it possible for the half-DNA in the egg, and half-DNA in
the sperm to set off a chain reaction of reproduction that
eventually will create a whole, new living being.
Call it a simple, natural chemical recombination, or call it
the will of God. Either way the results are the same. Without it,
you and I wouldn't be here, nor would anything else that's alive.
Cloning makes use of this. Even when the cells of your body
have specialized into being those of the eye, or of a muscle, or
a nerve or whatever, they *still* contain the complete genetic
code of what you are. (The only place this is different is with
the egg of a female, or the sperm of a male, in which case the
structure is halved - sorta. The details of this could fill a few
thousand issues of the magazine easily.)
Scientists haven't advanced all that far in this field. They
*have* come along far enough to show that DNA recombination is
also natural. It happens, and without a whole lot of help (unless
you're religious, in which case it gets all the divine help it
needs).
Evidence and Decay
Any competent scientist can carry out these experiments, and
will get the same results. The elements within an organic
compound automatically join together, and join together again.
Take two parts hydrogen and one part oxygen, provide a bit of
energy, and you get water. Every time. Take that same pure water
and break it apart (such as by electrolysis) and you get two
parts of hydrogen to one part of oxygen. Every time.
There are quite a few people who deny these facts - who say
that the results were rigged, or worse yet that the results are
teh effect of the devil getting into the laboratory (or into the
scientists, and causing them, and their assistants, and their
staffs, and their colleagues, etc. to lie).
What these experiments show is that nature quite . . . well,
naturally . . . causes inorganic substances to combine into ever
more complex organic molecules under certain conditions - the
conditions that existed (and still exist to a smaller extent) on
earth. Deny it all you wish. You can yell as long as you wish
that gravity doesn't exist, but the next time you drop a hammer
it *will* fall.
From here we drop into the realm of speculation. Since this
does happen, does it necessarily mean that given sufficient time
true and recognizable life forms will come about?
Scientists have been carrying on organized and painstaking
research for about 30 years. The earth had millions and millions
of years for its own "experiments." We may never know what the
next step in the chain would be, simply for lack of time.
So this part will remain a matter of speculation for the
foreseeable future. It's entirely likely that the "final truths"
may never be known - or if they are, won't be for tens of
thousands of years.
Meanwhile we have other things to look at that *do* exist,
such as the remains of creatures that once lived.
It has been argued that archeological finds are useless for
proof of evolution because there are gaps. Indeed there *are*
gaps, sometimes of thousands of years.
But then consider the difficulty involved in having anything
at all remain after such a period of time. Some very special
conditions must exist.
Maybe you've once buried a favorite pet in the backyard.
Then later on, out of curiosity, maybe you tried to dig it up
again, only to find that nothing was there. All that can happen
in just a few years. (If you don't believe it, try an experiment
on your own. Bury something like a dead mouse, mark the spot and
dig it up 2 years later.)
Imagine the same effects of nature over a period of, say, 20
or 30 million years. And imagine them taking place on creatures
that are more simple than earthworms. (How many earthworm
skeletons do you think you'll find, however long you dig?)
There is also the argument that things left on the surface
take even longer to decay. Fine. That's true within limitations.
You can test the validity of this easily by leaving another dead
mouse on the ground for a year. By then it will still be gone.
The lack of evidence isn't so astounding. It's the fact that
any evidence at all remains that is astounding. Take something
large and bulky, like an elephant and bury it directly in the
ground. Just 100 years later you'll be lucky to find bone
fragments. A thousand years later you still *might* be able to
perform complicated chemical tests of the soil to show a
predominance of certain substances like calcium. Ten thousand
years later, not even that is likely to remain.
So missing links aren't the befuddlement of science - they
are the norm. If those links *were* there and easy to find, it
would be time for science to redefine itself. The lack is more
understandable, and more scientifically valid.
Dating
One of the key arguments against any finds is the dating of
that particular find. Is the scientist studying the jawbone of a
pig slaughtered 10 years ago? Or the jawbone of some ancient
creature that died 10 million years ago?
There are two general methods of dating. One takes a reading
of the radioactive elements that are still present in the
remains, along with the elements that this (or those) radioactive
elements decay into. The most well known of these is carbon-14,
which is a relatively common isotope of "regular" carbon.
Basically it works like this:
The rate of decay is a known factor. So is what the
radioactive element becomes after decay is complete, and what it
becomes in each stage along the way. By studying the proportion
of decayed elements, it's a relatively simple matter to backtrack
mathematically to determine how much was there in the first
place, and from there (once again mathematically) to figure out
how long it took to happen.
It's kind of like a natural clock.
There are a few problems with this form of dating, but it is
generally accepted to be accurate to within a few thousand years
or so, depending on how old the object is (was?) in the first
place. Other things can sneak in as well, causing a dating to be
more inaccurate.
Even so, if this form of dating is even as much as 10%
inaccurate (it's more like 1% or 2%), the findings are still
enough to provide definite evidence within allowable error. If
the dating shows something to be 1 million years old, and the
error is 10%, that means that the object under study is somewhere
between 1,100,000 and 900,000 years old. And if the dating is
totally inaccurate as much as 10% of the time (this is more like
0.1%), that means that it's correct enough for the other 90%
(actually the other 99.9%).
The second method is more simple, although less accurate.
You can see a part of it taking place right in your own yard, and
all over the world to a much larger extent.
Set something down in the yard. Within a couple of days it
will have a visible coat of dust on it. Leave it there long
enough it will be covered up completely. If you live on a sandy
desert where the wind blow constantly, it will take even less
time yet. (On the deserts of northern Africa, which was the site
of many battles during World War II, dig around and you can find
tanks and other machinery completely buried.)
Other forces of nature also assist in burying objects - the
flow of a river, earthquakes or volcanic eruptions, the wash of
the sea, rain, lack of rain, etc., etc., etc. All the forces of
nature combine.
The conditions on the surface change from time to time. What
is now a great desert in Arizona was once an inland sea.
Minnesota, with all its lush plantlife and thousands of lakes was
once completely covered by ice. Consequently, the "ages" tend to
gather as distinct layers.
Take a look at the mountains around the valley. Some were
produced volcanically. Others are huge hunks of the ground pushed
up by related forces. On these you can actually *see* some of the
layers.
Quite obviously (or what should be obvious), the deeper the
layer, the older are the things found in it. There are times when
this is not true - such as when the earth has literally turned
over from the forces of nature. But in this case, the signs of
the turnover will also be present, and the scientists *still*
have some idea of the time frame.
Imagine that in one layer you find the fossil of fish, with
all the fins essentially intact as they are with fish today.
Through the layers beneath that you find other fossils of fish,
with each successive layer showing that the fish of the time were
more and more simple.
Conclusion
It's true that there have been hoaxes. There have also been
cases when a scientist or two will twist the findings to prove a
particular pet theory.
However, to claim that ALL findings are hoaxes, and that ALL
scientists are liars and frauds, is a bit ridiculous.
It has also been said that all the findings are inconclusive
and mean nothing, other than another case of scientists misinter-
preting data.
This is a valid point. Scientists are just people, and can
make mistakes. History is full of such cases - and in fact the
history of science is little more than a long study of errors.
However, and at the same time, it has to be taken into
account that the studies are becoming more and more accurate. As
new studies are completed, they aren't showing that the previous
scientists were misinterpreting, but that they were correct in
most instances - or even underestimated the results.
Just because scientists have made mistakes in the past
doesn't mean that they *always* make nothing but mistakes. If we
were to take that attitude - that science is always error and to
be dismissed out of hand - you're going to have to toss out more
of your beliefs than just an objection to evolution. And you
can't logically (or justifiably) toss out one faction that makes
you uncomfortable and keep the rest - can you?
Nor can you casually toss aside the findings of several
thousand scientists who have all come to the same results.
Beyond that there is the simple logic of the idea - although
you *can* argue that point successfully, I guess. Things like -
if a mountain under study has layers that took 50,000 years each
to form, and you find item A in layer 12, and item B in layer 13,
then item B is about 50,000 years older than item A.
Literally thousands upon thousands of researches have been
done that show that every creature on earth slowly changes. Some
of those changes can be seen in a single generation, particularly
with the simpler life forms. More extensive changes show up in
fossil records. And in both cases, this happens again and again
and again and again.
Then along comes Harold Urey and those who followed him,
with an ever increasing amount of evidence that shows that
organic molecules naturally form from the elements that would
have been on earth when it was first formed.
Coupled together, the indication is that evolution begins on
the molecular level and continues up through the most complex
creatures. It's the way of nature. Deny it all you like - or play
ostrich if you wish. It won't matter.
Scream and shout all you want that the earth is the center
of the universe. But, just as science showed such thoughts wrong
then, and just as the screaming and shouting and threats then
didn't move the earth from its orbit around the sun . . . .
UNTIL NEXT TIME
Well, *that* should get some discussion going!
I will ask a couple of things, however.
Feel perfectly free to take either side. But whichever side
you take, don't allow yourself to drop into emotional attacks or
insults. That's easy to do with a controversial topic, but it
will get you nowhere. Not here and not in life, either.
Ya see, we had this discussion before, on Zephyr. A couple
of people decided that the way to "disprove" the facts was to
first deny they existed, and then to insult anyone who believed
those facts, or who took the time to find them to be true. And
these same few stormed out in a huff because everyone was
"picking on them."
So, if you find yourself getting angry or upset, don't leave
a reply at that time. Log off, calm down, and think things over.
Second, I am extraordinarily busy at the moment. Everything
in this week's issue is verifiable, but I simply don't have the
time to go through my files and dig out the actual references.
While it is a perfectly valid, and even desirable, point to
demand that someone making a statement provide the references,
I'll have to pass this time. I apologize for this, but will just
have to leave it up to you to find those references on your own.
It's not difficult anyway. Just go to any decent library with a
good science section and look up the subject. Or get out an
encyclopedia and look up the names Harold Urey, Carl Sagan and
Cyril Ponnamperamu. These were the 3 prime movers of the original
biochemical studies. It's not secret information and is there for
anyone to find who cares to look.
And, yes - that's a cop out on my part. I just don't have
the time right now to do better. But, just because I don't have
the time to list the references for you doesn't invalidate the
facts. As I said above, check them out for yourself.
As to next week - or next issue if it takes more than a week:
Once again I have to resort to a cop out. I really don't
know what I'll be doing. For the third (or is it fourth?) time, I
am quite busy right now - with 3 books due to be put into the
publisher's hands in the next month. Then there's the new baby,
and . . . well, you get the idea.
Perhaps another piece of fiction?
