The Galapagos Islands contain a very large
number of different finches, as well as flamingos, penguins, giant tortoises,
iguanas, seals, butterflies, and insects. Forty-two percent of the plants found
on the Galapagos, seventy-five percent of the bird species and ninety-one
percent of the reptiles and mammals are not found anywhere else in the world.
Darwin’s name is long associated with these finches though he did not discover
them, properly identify them or even use them in his book, Origin of the Species by natural Selection.
Actually, it was not Darwin who mythologized
the Galapagos finches, but 20th century evolutionists such as Percy Lowe and
David Lack. Lack's 1947 book Darwin's
Finches was an icon-maker for the Darwinists [1]. Thus
Darwin's finches have been studied more than any other bird families. In
1991 Peter Grant claimed he had found 20 cases of natural selection turning a
middle ground finch into a great ground finch. This, he claimed, was direct
evidence of evolution [2]. So has one species been transformed into another? A species is defined
as a population consisting of individuals with similar structural and
functional characteristics, able to mate only with one another in nature, and
which are unable to mate successfully with other individuals outside their own
population.
According to this definition, it is incorrect to
claim 14 distinct species of finches in the Galapagos Islands as they
interbreed significantly. Indeed, Grant himself admits that a maximum of 6
separate species and perhaps less than the 14 recognized currently [3]. Darwin’s claim
in the Origin was that his natural
selection could be responsible not only for variation within a species but for
the origin of species or transpeciation from one species to another. The Galapagos finches have no genetic
differences among them [4]. Max Planck Institute and Princeton
University in 1999 announced that the traditional classification of Galapagos
finches was not apparent at the molecular level [5] and
Hau and Wikelski state, "There is
no evidence for an absolute genetic barrier between Darwin's finch species.
Thus many species can potentially hybridize.” [6] All evidence points to
the fact that they are all the same species.

Much of Grant’s claim
emphasized the change in beak size. The average size of the Galapagos finches'
beaks increases or decreases according to food resources and that depends
greatly of the rainfall. El Niño takes place at irregular intervals
every two and 11 years, and at different levels of intensity, also alters the
climatic balances. At such times there is excessive rainfall; subsequent years
are then generally dry and arid. In years of plentiful rain, ground finches can
easily obtain the seeds they need to grow and breed. In years of drought,
however, the plants on the islands may produce a limited amount of seeds and
the number of finches decrease. The
rainfall in 1976 was normal, but fell to one-fifth in 1977. During the drought
there was a significant drop in the quantity of seeds and a major reduction in
the numbers of ground finches. The population fell 85%. The finches that survived the drought were rather larger than normal and had
5% wider beaks.
When the rains returned the
Darwinian process reversed and the finches returned to their previous size and
previous beaks. Yet, in his book,
Weiner described this change in the beak as "the best and the most
detailed demonstration to date of the power of Darwin's process. [7]" The fact that a reversal occurred after the drought
resulting in no long-term evolutionary change is neither mentioned nor
interpreted. California University biologist, Dr Jonathan Wells,
stated the claims from the finch evidence were "exaggerated" [8]. Berkeley
University's Professor Phillip Johnson said in the Wall Street Journal, "When
our leading scientists have to resort to the sort of distortion that would land
a stock promoter in jail, you know they are in trouble.[9]"
In the research on Darwin’s finches the term natural selection has been used as
a substitute for Darwinian evolution. However, Darwin clearly proposed that a
change sufficient to create a new species was possible. In his day a
substantial change in characteristics may have been essential criteria but in
the age of Mendelian genetics and DNA splicing a new species must exhibit new
DNA and chromosomal structure. This evidence is completely lacking.
The error in the Darwinist thinking
is one of extrapolation. A cow jumps over a two-foot fence. From this you
cannot deduce from that that a cow
can jump over the moon. Nonsense! The cow's
muscle power is absurdly inadequate to propel it to the moon. As we have seen
the power of natural selection can make minor modifications to one aspect of
its physiology. But, it is absurdly inadequate to change the DNA that allows reproduction possible. The general public's lack of biological knowledge causes them not to appreciate the
extrapolation problem and thus the error in the Darwinist conclusion. Rather than admit that there is no finch evidence for transpeciation Darwinists, such as Grant and Weiner, have substituted
subspeciation. Bait and switch is not a scientific principle.
Now in Genesis Chapter 1, the text
clearly states that everything brings forth "after its own
kind". Surely, if fish produce fish and only fish and cattle produce
cattle and only cattle then finches produce finches and only finches. So
subspeciation is no problem for Genesis. If Darwinism is the natural selection that
produces subspeciation in finches - finches that reproduce more finches - then
it agrees with Genesis 1. Statements that claim that Darwinism refutes Genesis
1 then are simply false. If, however, Darwinism means fish evolve into cattle
which evolve into apes which evolve into humans then the natural selection of
finches into finches is moot. Darwinists must then admit that it is "other" evidence that "proves" evolution. But these other mechanisms have no results that demonstrate their effectiveness and so do not demonstrated the
Bible is disproved. Darwinists mechanisms are either effective and agree with the Bible or are ineffective. Am I to be impressed by these claims?
