A Critical Look at Macro-evolution

The Mechanism of Evolution
The mechanism of macro-evolution has never been observed. It usually is presented in
this fashion: Starting with some form of unorganized chemical matter, a rise in
complexity took place randomly through the influence of energy. It was preserved by a
mysterious process known as (a progressive form of) natural selection. This rise
in complexity was preserved as a result of some undefined advantage. This selection
process was repeated over and over again acting upon the latest example of preserved
complexity.
Because this rise in complexity itself is by random chance, the existence, preservation
and increase in complexity are all seen as taking place over vast spans of time. This
vertical progression to a higher complexity is said to bring forth new and different
kinds of life (Macro-evolution). Present life forms being the most recent expressions of
this (evolution) process.
1)Unorganized matter + energy + chance mutation + time = complexity
2)Complexity acted upon by progressive natural selection = preserved complexity
3)Complexity + time +mutation+ natural selection = increased complexity = new kinds

A Critical look at the Mechanism of Evolution
1)A progression from chaos to complex order is not observed in nature without a
preexisisting code of purposeful instructions. Energy moves from a higher to a lower
level (2nd law of thermal dynamics) Matter does the same. The stuff we buy wears
out, our bodies wear out etc.
2) Natural Selection is not observed as a progressive mechanism in nature; it is
observed as a conservative mechanism. It preserves the norm and assures that the
abnormal condition does not become predominate in a population. Ex. diabetes
3) Mutations are not observed in nature as beneficial. Multiple mutations are
deleterious even in bacteria.
4) Transitional forms from one kind of creature to another kind of creature are not
observed
in nature either in the fossil record or as living examples.
5) Vast time periods are not observed as making life probable from inorganic matter.

The evidence for evolution
”No theory should be presented without some evidence” Taken from Foundamentals
of Historic Geology by David Dathe.
It is said that Darwin derived his theory from his five year voyage on the Beagle.
His field studies in Britain and Library Research.
The Claim of Anatomical Evidence
1) Embryology – A close resemblance of embryos of certain organisms.
2) Homology – A similarity in certain structures such as bone and limbs in some animals indicates they have been modified for different functions.
3) Vestigial Structures – Organs inherited from an ancestor that now serve no purpose.



The Claim of Biological Evidence
1) Selective Breeding – Microevolution has been demonstrated in selective breeding.
Ex. Changes in plants and animals.
2) Ontogenetic Changes – Evolution demonstrated during an organisms life time. Ex tadpole to frog or caterpillar to butterfly.
3) Biochemistry – Similar biochemistry of organisms implies common ancestry.
4) Paleontological - Evolution is clearly documented in the fossil record.

A Critical Look at the Evidence for Evolution
With the exception of vestigial organs and selective breeding, all of the above
are arguments from Homology. That is that if something is similar to something
else it must be related.
Anatomical
1) The recapitulation theory was found to be a hoax.
2) Similarity is a weak argument as evidence for evolution just as saying the wheels on a motorcycle indicate it evolved from a bicycle. The motorcycle requires new and different information not found in the bicycle or a predecessor. A tornado rearranging parts and pieces on a bicycle even with natural selection picking out the” best” would never evolve into the motorcycle regardless how much time.
3) If there were true vestigial structures they would indicate a loss of information not an increase as required by evolution. Ex. Blind cave fish. Loss of function from lack of use an example of 2nd law of thermodynamics.
Biological
1) Selective Breeding is simply expressions of genetic variation found within the kind. It is just selecting a particular book from a library containing but one subj.
2) Ontogenetic life cycles - Many creatures have an aquatic stage in their life cycles. Ex. Salamanders, many insects such as mayflies, dragonflies, mosquitoes, etc. These creatures are not slowly evolving out of water but rather completing their life cycles through water. Their life cycle is a genetic program being executed according to existing instructions. (see note below) Winged insects fossils have been found in what is considered to be very old strata Their supposed evolution is a mystery.
3) Similar biochemistry simply implies that organic life on a common planet have common organic functions and were designed by a common designer.
4) There is no evidence in the fossil record that clearly documents evolution; In fact the fossil record argues against it. ex. Cambrian explosion.
Note: Metamorphosis (changing form) in creatures is not an indication of evolution.
Some aquatic bugs are said to undergo gradual metamorphosis (paurometabolous) where the immatures (without wings) share the same habitat with the adults. Dragonflies, Mayflies etc.are said to undergo incomplete metamorphosis (hemimetabolous) where the immatures live in a different habitat than the adults.
Caddisflies, Dobson flies etc. are said to undergo complete metamorphosis
(holometabolous) where the immatures are dramatically different from the
adults. The life cycles of all insects that undergo metamorphosis are complete and adequate by design and are not a picture of evolutionary transistion to a more favorable form.
