Most evolutionists believe that Natural Selection (NS) and chance mutations
over enormous amounts of time propel evolution. In theory, NS suggests
that the most fit individuals survive, reproduce, and redistribute
into the diverse eco-geographical regions of the world.
It is important to recognize that even creationists recognize NS. It is
a process we observe in this fallen world. Edward Blythe, a 19th century
scientist postulated NS twenty-four years prior to Darwins Origin
of Species. Creationists recognize that NS can effect change, but only
on a small scale. It enables a species to maintain its adaptation, not
improve upon it. In fact, NS is a friend to the creation model, promoting
a purity of Gods created kinds.
Not only is NS a friend to creation, but it presents major problems for
evolution. Evolutions imaginary transitional forms would have incomplete,
unusable new structures (i.e. partial wing, partial arm etc.). These isolated,
rudimentary aberrations would be inferior to the fully formed, fully functional
structures of their parents. An intermediate form would be a detriment,
not having selective competitive advantage.
In other words, natural selection over the long run does not seem
to improve a species chance of survival but simply enables it to
track, or keep up with, the constantly changing environment.1
The famous biologist DArcy Wentworth Thompson {1942} expounded on
the negative role of NS: We begin to see that it is in order to
account not for the appearance but for the disappearance of such forms
as these that NS must be invoked. And we then, I think, draw near to the
conclusion... that the great function of NS is not to originate but to
remove ... we see in NS an inexorable force whose function is not to create
but to destroy ---to weed, to prune, to cut down and to cast onto the
fire.2 Wesson says, Natural selection is credited with seemingly
miraculous feats because we want an answer and have no other.3
But what about the famous textbook proof of evolution, the Peppered Moth
study by Kettlewell during the 1950s ? Tree bark lichen died as
the industrial pollution deposited soot into nearby forests. Consequently
the white bark turned black in coloration. As a result, the light moth
population declined and the dark moth population increased. Were
told the black moths had a selective advantage of camouflage, since birds
ate the more visible white moths.
However, this is not an example of Evolution. This environmental stress
did not promote any new moth types (i.e. changes within a kind - subspeciation),
nor were there any changes between kinds (i.e. moth to butterfly - transpeciation).
Both populations of moths were present prior to the industrial pollution.
No accidental, chance mutation was needed to create this new variation.
In fact, both moth types were classified under the same Genus & species
(Biston betularia). The only difference between them is that the darker
moths have more melanin pigment. Since Kettlewells study exhibits
a population color shift, and not a new population origination, this is
definitely not an example of evolution.
Is this really an example of NS? That depends on the cause of these changes.
NS may have had a role if the increased visibility of the white moth population
was naturally selected against.
However, another viable explanation is that the majority of white moths
simply migrated to trees in outer rural areas with light colored tree-bark.
A population redistribution would not fit the NS mechanism. Since the
1960s, improved industrial pollution controls have helped restore
lichen covered tree trunks to their prior light coloration. To a large
extent, the light colored moths have returned as well.
Are these adaptations synonymous with evolution? No. Adaptations speak
of the enormous genetic potential of living creatures. The incalculable
complexities of the genome (i.e. total genetic potential of a population)
provide a tremendous resource of variation within a kind. This preprogrammed
gene pool gives created kinds the ability to adapt to a variety of conditions.
Even Kettlewells study itself has been called into question. Research
by British scientist Cyril Clark spanning 25 years determined peppered
moths to be primarily nocturnal. Rarely do they rest on tree bark during
the day. Their daytime absence would minimize enormously the effect color
would have on predation. (Kettlewells original photos were obtained
by gluing dead moths onto bark).
Other studies have not repeated these original results. In fact, a poor
correlation between population numbers and bark color exists. Even evolutionary
biologist Jerry Coyne (University of Chicago), agrees the peppered moth
story, which was the prize horse in our stable, needs to be
discarded.4
Since God is the author and designer of this world, He is central and
not peripheral to science. The most brilliant minds of science pale infinitely,
to the wisdom of our Lord Jesus Christ. The same Creator that spoke the
heavens and the earth into existence, became man and died for our sins.
The gospel of Evolution is a gospel of naturalism, atheism and humanism,
whose savior is NS, mutations, and vast epochs of time. It denies the
very existence, character, and identity of the living God. God and God
alone deserves our hearts, our lives, our all.
