Jerry Coyne, in his new book entitled Why Evolution is True, conveniently circumvents any reference to the butterfly, as does Darwin-Discovering the Tree of Life by Niles Eldridge. The California State sponsored website, “Understanding Evolution,” website completely ignores the notorious nature of butterflies—metamorphosis.

So, why is the evolution industry silent on butterfly metamorphosis? The answer is simple—the same DNA is found in all four life cycles; egg, caterpillar (larva), cocoon (pupa) and butterfly (adult). Metamorphosis, to the theory of evolution, is an enigma.

For over 3,500 years, to the Egyptians, Chinese, and Greeks, the butterfly symbolism was derived from the unique butterfly life cycles. The egg first develops into the caterpillar before transitioning into the cocoon. Amazingly, inside the cocoon, the caterpillar is destroyed before developing into the stunningly colorful butterfly cycle. Continue reading more

Ignorance more frequently begets confidence than does knowledge.  Charles Darwin

Darwin argued in The Origin of Species that evolution develops through the processes of natural laws, changing the simple into the complex, in ways analogous to the laws of gravity -

[W]hilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been, and are being, evolved.

The chromosome is the organizational structure of DNA and proteins in cells. DNA contains the nucleotide sequences that form the genes. During the twentieth century, determining the number of chromosomes in species has been in the investigative forefront.

Since Darwin envisioned that “natural selection acts solely by accumulating slight, successive, favourable variations; it can produce no great or sudden modifications”, according to the theory, chromosomes were expected to demonstrate evolution from the simple into the more complex via “slight, successive” changes.  

While the simplest known organism, Mycoplasma hominis, does have only one chromosome, Darwin’s simple to complex theory quickly breaks down. Unless the Gorilla, Chimpanzee, Cow, Guinea Pig, and Goldfish evolved from Humans, the simple to complex theory of evolution is simply incompatible with the scientific evidence.

The American Museum of Natural History, in the New York presentation of the Darwin exhibit organized by curator Niles Eldredge, declares

A century and a half ago, Charles Darwin offered the world a single, simple scientific explanation for the diversity of life on Earth: evolution by natural selection.

The exhibit explains – “Natural selection is a simple mechanism that causes populations of living things to change over time.”

“Simple”, according the Answers.com means 1) having or composed of only one thing, element, or part, and 2) not involved or complicated, easy, a simple task. A common antonym of simple is difficult.

Perhaps, the zeal over evolution caused Eldredge to overlook what Charles Darwin actually wrote in The Origin of Species: the term simple was only used 56 times, while difficult was used 213 times. Darwin even entitled Chapter VI – “Difficulties of the Theory.” Chapter VI became an add-on chapter after the 1^st edition. There is no “simple” chapter.

Jerry A. Coyne, one of the leading evolutionists at the University of Chicago, in his new book entitled Why Evolution is True (2009) writes “much confusion and misunderstanding surrounds evolution” even though “the modern theory is easy to grasp.” The question is how can a theory be “easy to grasp” and still be surrounded by “much confusion”?

But what could the confusion be over? Here are some examples.  Charles Darwin wrote in The Origin of Species - “There is no logical impossibility in the acquirement of any conceivable degree of perfection through natural selection”. Coyne contradicts Darwin by stating – “natural selection does not yield perfection”. Over a trivial issue, confusion reigns over whether natural selection can or cannot produce perfection in nature.

Presumably, to show how easy the theory of evolution is to understand, Coyne features what he calls the six basics of evolution: “evolution, gradualism, speciation, common ancestry, natural selection, and nonselective mechanisms”. For Coyne, natural selection is not the exclusive driving force of evolution.

Niles Eldredge, evolutionary biologist and curator of the American Museum of Natural History, disagrees. Niles Eldredge, architect  and designer of the museum’s currently touring Darwin exhibit in the companion book Darwin, Discovering the Tree of Life (2005), credits Darwin with discovering the actions of natural selection—the essence of evolution: “When [Darwin] formulated the principle of natural selection, he had discovered the central process of evolution.”

Unlike Coyne, Eldredge envisions evolution acting exclusively through the process of natural selection: “A century and a half ago, Charles Darwin offered the world a single, simple scientific explanation for the diversity of life on Earth: evolution by natural selection.” Unlike Coynes six basics of evolution, Eldredge uses a VISTA acronym for natural selection that stands for Variation, Inheritance, Selection, Time, and Adaptation.

Differences in approach even between Coyne and Eldredge, exemplify why evolution theory continues to be confusing—even on the basics. The teaching of evolution is in chaos. Coyne pines “most of my university students who supposedly learned evolution in high school, come to my courses know almost nothing about this central organizing theory of biology.” Could it be because a unified theory of evolution simply does not exist?

Even university science major graduates seem to be no better. T. Ryan Gregory and Cameron A. J. Ellis, in their paper entitled “Conceptions of Evolution Among Science Graduate Students” published in BioScience 59(9):792-799 (2009), surprizingly found that less than 30% of students pursuing advanced science degrees could correctly identify even the basic principles of evolution.

The reason is—a comprehensive theory of evolution simply does not exist. Even with the convening of the most respected evolutionary scientists at the Altenberg Summit in 2008, no consensus was reached on a comprehensive theory of evolution.

Given the flood of available evidence, in the wake of Crick’s Central Dogma collapse, evolution is a theory that remains in chaos—now more than ever.
