The
strength of any scientific theory is measured by its ability to make
predictions. It works sort of like this: I might have a guess about
what causes (or caused) some phenomenon. I would then say, “If my
theory is true, I would expect to find this other thing.” If that
other thing is found, it gives weight to the theory that it might be
correct. If that other thing is not found, then it could be evidence
that the theory is not correct.
I'll
give you a hypothetical example of how this works. Before we ever
went to the moon, pretend that I insisted that the moon is made of
cheese. If my theory were true, I could predict that any rock
brought back from the moon would actually be cheese. Technically,
theories are never “proven” to be true. If the rocks brought
back from the moon did turn out to be cheese, it still doesn't mean
the entire moon is made of cheese – it could have been just those
few rocks. Even so, it does make my theory seem more likely.
However, if all the rocks brought back turned out to be ordinary
rocks and none were cheese, it's very strong evidence against my
theory.
Some
people claim evolution is a strong theory that has made many
successful predictions. What they always fail to discuss is how
evolution is so plastic a theory that it's virtually impossible to
falsify and even some of the things we might predict if the theory
were true are epic fails. I thought I'd take a moment and discuss
just a few of evolution's failed predictions.
Radiometric
dating: Certain, naturally occurring substances are unstable and
so will decay over time until it becomes a stable substance.
Uranium, for example, decays over time and eventually becomes lead.
The rate at which the decay occurs varies from substance to
substance. Some decay at an extremely slow rate while others decay
more rapidly (relatively speaking). By measuring the ratio of the
parent/daughter elements (uranium/lead, for example), scientists can
estimate how long the decay has been occurring. Many scientists
consider radiometric dating to be the final word in determining the
age of any sample and it is from radiometric dating that many people
are convinced that the earth is very old. If radiometric dating
actually dates things accurately, we could make a few predictions:
Prediction
#1: Newly formed rocks should not have any of the daughter
element present and should show an age of “zero.”
Results:
Rocks
formed at the Mt St Helen's eruption were dated using potassium/argon
dating, the samples yielding ages up to 2.8 million years even
though the known age of the rocks was 10 years old. FAIL.
Prediction
#2: Carbon 14 is an unstable element found in all living things.
As living things breath and eat, they accumulate C14. Once the thing
dies, the C14 begins to decay and becomes C12. The key difference in
this radiometric dating method and those discussed in the previous
paragraph is that the decay rate of C14 is much quicker than many
other types. It has a half-life of only 5,730 years. Due to its
short half-life, we can predict that samples more than 100,000 years
old should have no detectable C14 remaining in them.
Result:
An 8 year long endeavor by creation scientists known as the RATE
project, has found it is impossible to find any old samples
without detectable levels of carbon. Even diamonds, the hardest
natural substance and virtually impossible to contaminate,
consistently yield trace C14 even though they are supposed to be a
billion years old. FAIL.
Progression
in the Fossil Record: According to secular dating, the rock
layers represent the accumulation of sediment being laid down over
time. The layers further down are older than the layers above them.
Where fossils are found in the layers supposedly represents when
those creatures lived. Creatures found in fossils in lower strata
lived before the creatures found above them.
Prediction
#3: If evolution were true, there should be a clear progression
of simple to complex in the fossil record where the older creatures
are more primitive than the younger creatures.
Result:
Dinosaurs allegedly evolved into birds. However, I recently wrote
about feathers
identified as 78 myo yet are still described as being “nearly
identical to those of modern birds.”
I also wrote about the supposed human ancestor, Australopithecus
afarensis. This very
ape-like creature was found in the same age of rocks as the Laetoli
Footprints which are described as “almost
indistinguishable from modern human footprints,”
matching our feet in both the toe pattern and stride. In both of
these cases, and many others I could cite, we see evidence of modern
creatures living simultaneously as their supposed ancestors. There
is no clear progression in the fossils of simple to complex. FAIL.
Transitional
Forms: Evolution is a history of descent with modification. A
lobed fin becomes a leg which become wing. A fold in the skin
becomes a scale which becomes a feather. The structures found on
every creature of every species are simply adaptations of more
primitive structures found on the creatures' ancestors.
Prediction
#4: If evolution were
true, we should expect to find volumes of fossil evidence showing
creatures in transition from one species to another. In Darwin's own
words, “innumerable
transitional forms must have existed.... [J]ust in proportion as
this process of extermination has acted on an enormous scale, so must
the number of intermediate varieties, which have formerly existed on
the earth, be truly enormous.”
We
should not be able to turn over a shovel of dirt without finding
another transitional form.
Result:
Darwin himself was surprised that we didn't find, “every
geological formation and every stratum full of such intermediate
links.”
After more than a century and a half of looking, and the trillions
of fossils that exist, evolutionists have – at most – a few dozen
examples of transitional forms and even most of these are suspect.
The “innumerable”
amount we would expect to find are simply not there. FAIL.
The
Appendix: As we've already discussed, evolution is a history of
descent with modification. Over time, some structures have
supposedly lost their original function and have either become
useless or have been adapted for some completely different function.
Such structures are called, “vestigial.” The appendix is perhaps
the most touted example of a vestigial structure.
Prediction
#5: The appendix appears in many different species of mammals.
If descent with modification has occurred, we should be able to trace
the appendix along the so called, “tree of life” and find that
all the creatures who have an appendix also share a common ancestor.
Result:
The appendix appears in some species of primates, rodents, and even
marsupials but is absent from the intermediate groups linking these
species. It
appears on the tree of life in no discernible pattern. FAIL.
Tiktaalik:
I bring this up because it is often cited by evolutionists as an
example of a successful prediction made by their theory. It was even
used by Bill Nye in his debate against Ken Ham. The most commonly
accepted understanding of history is that life began in the sea and
evolved onto land. If this has occurred, scientists would expect to
find fossil evidence of creatures with structures in transition from
sea-to-land.
Prediction
#6:
Based on their understanding of when the supposed transition of
sea-to-land occurred, researchers began exploring an area of exposed,
Devonian deposits in the Canadian Arctic in hopes of finding fossil
evidence of a creature in transition from sea-to-land. They found
Tiktaalik.
According to one
website detailing the prediction, “Not
only was it exciting to find a new species, but it was made all the
better by the fact that scientists had predicted the existence of a
creature like this all along.”
Result:
A few years after the discovery of Tiktaalik,
a track of fossilized footprints belonging to a tetrapod were
uncovered in a quarry in Poland. They were dated according to
evolutionary dating methods to be 18 million years older than
Tiktaalik.
This would mean that fully evolved, ambulatory tetrapods were
walking around millions of years before their supposed ancestor,
Tiktaalik,
ever
lived
(see failed prediction #3). FAIL.
In
summary, I'll just say that I'm not sure of any successful
predictions the theory of evolution has made. Many of those that
endure are what I call, “predictions after the fact,” like “if
evolution were true, I would predict that creatures could reproduce.”
These types of “predictions” are worthless. I only know that
there are many, many failed predictions. It's generous that we still
even call it a “theory.”
