Of all the facts in The Origin of Species, embryology was the most important in support of the theory. In a letter to Asa Gray in September 1860, Darwin wrote – “embryology is to me by far the strongest single class of facts in favor” of the theory.

Then, just two months before the release of the first edition of The Origin of Species in September 1859, Darwin wrote to Charles Lyell, “Embryology in Chapter VIII is one of my strongest points I think.”

Darwin was fascinated by embryology. Writing in his autobiography, Darwin recalls: “Hardly any point gave me so much satisfaction when I was at work on the Origin, as the explanation of the wide difference in many classes between the embryo and the adult animal.”

To the point, Darwin writes – “We have seen in the first chapter that the homological [similar] structure of man, his embryological development and the rudiments which he still retains, all declare in the plainest manner that he is descended from some lower form.”

Darwin along with Fritz Müller (1821–1897) and Ernest Haeckel (1834–1919) were following in the footstep of Karl Ernst von Baer (1792–1876). Baer promoted the concept that a species’ embryological development (ontogeny) retraces the species’ entire evolutionary development (phylogeny).

In the case of man, then, the human embryo begins as a single cell and is progressively transformed into a tadpole, then to a fish, to an amphibian, to a monkey, and finally to man. In other words, at the different stages of development, the embryo is actually a series of ancestor species. The sequences of the embryo retrace the steps of evolution. Haeckel coined this process with the now-famous phrase “ontogeny recapitulates phylogeny.”

In the case of the appendix, then, the rise and fall of the appendix should be seen in the human embryo to demonstrate our presumed evolutionary human ancestry—from a functional to a non-functional organ. The question is does the evidence match the theory? The answer is – NO.

The reasons why the answer is NO, include  

• The appendix is not consistently found throughout the animal kingdom, occurring in only a few diverse mammals
• Not until the fifth fetal week does the appendix begin to develop
• Only after the fifth fetal month does the proximal end start differentiate into the true caecum
• Maximum growth of the appendix does not occur until after birth when the neonate takes on essential bacteria to reside in its colon
• Lymphoid follicles do not appear in the appendix until two weeks after birth at the same time that colonization of the large bowel with bacteria.

Contrary to the theory, at no point in the development of the appendix in the human embryo does arise and decline into a vestige organ. Rebecca E. Fisher, Ph.D., Postdoctoral Fellow from the Center for Functional Anatomy & Evolution Johns Hopkins University School of Medicine, in a review article entitled “The primate appendix: A reassessment” concludes that “the evolutionary history of the appendix has also proven difficult to trace.”  

The evidence on the development of the appendix now clearly stands to demonstrate the utter fallacy of the long-standing “ontogeny recapitulates phylogeny” theory of evolution.

Jerry Coyne’s (2009) contention in Why Evolution is True that, “our appendix is simply the remnant of an organ that was critically important to our leaf-eating ancestors, but is of no real value to use” is another clear example of deception used in the promotion evolution. The evidence is clear: the appendix is not an evolutionary leftover.

The “vestige” status of the appendix originated with Charles Darwin in The Descent of Man (1871). In Chapter 1, Darwin writes -

“With respect to the alimentary canal I have met with an account of only a single rudiment [vestige], namely the vermiform appendage of the caecum… It appears as if, in consequence of changed diet or habits [disuse], the caecum had become much shortened in various animals, the vermiform appendage being left as a rudiment of the shortened part… Not only is it useless, but it is sometimes the cause of death”

Darwin’s concept of the appendix continued unchallenged until late in the twenteth century when clinical research began to demonstrate that not only does the appendix function to balance the bacteria in the gastrointestinal tract, the appendix plays an important immunological function. 

Loren G. Martin, professor of physiology at Oklahoma State University, stated in Scientific America -

“Among adult humans, the appendix is now thought to be involved primarily in immune functions. Lymphoid tissue begins to accumulate in the appendix shortly after birth and reaches a peak between the second and third decades of life, decreasing rapidly thereafter and practically disappearing after the age of 60. During the early years of development, however, the appendix has been shown to function as a lymphoid organ, assisting with the maturation of B lymphocytes (one variety of white blood cell) and in the production of the class of antibodies known as immunoglobulin A (IgA) antibodies. Researchers have also shown that the appendix is involved in the production of molecules that help to direct the movement of lymphocytes to various other locations in the body.”

Martin continues noting, “the function of the appendix appears to be to expose white blood cells to the wide variety of antigens, or foreign substances, present in the gastrointestinal tract. Thus, the appendix probably helps to suppress potentially destructive humoral (blood- and lymph-borne) antibody responses while promoting local immunity. The appendix–like the tiny structures called Peyer’s patches in other areas of the gastrointestinal tract–takes up antigens from the contents of the intestines and reacts to these contents. This local immune system plays a vital role in the physiological immune response and in the control of food, drug, microbial or viral antigens.”

Jerry Coyne (2009), professor at the University of Chicago, writes in his new book, Why Evolution is True that, “We humans have many vestigial features proving that we evolved. The most popular is the appendix.” Coyne claims that: “our appendix is simply the remnant of an organ that was critically important to our leaf-eating ancestors, but is of no real value to use.”

Classifying the appendix as “no real value” exemplifies how evolution adherents persist to be woodwinked by ideology. Mounting scientific evidence continues to demonstrate why evolution is NOT true.

Long denigrated as vestigial or useless structure, the human appendix is now known to have a number of specific functions. The most widely recognized function is as a “safe house” for the beneficial bacteria living in the human gut.” There are approximately 500 species of bacteria in the gut alone—the continued presence of beneficial bacteria is essential for good health.

ScienceDaily in an article entitled “Appendix Isn’t Useless At All: It’s A Safe House For Good Bacteria,” October 8, 2007, William Parker, Ph.D., assistant professor of experimental surgery along with R. Randal Bollinger, M.D., Ph.D., Duke University professor emeritus noted—”Our studies have indicated that the immune system protects and nourishes the colonies of microbes living in the biofilm. By protecting these good microbes, the harmful microbes have no place to locate. We have also shown that biofilms are most pronounced in the appendix and their prevalence decreases moving away from it.” One of the functions of the appendix is to serve as a microbe storehouse.

According to their study published in the Journal of Theoretical Biology, the bacteria in the human gut functions to digest food and produce vitamins, like Vitamin K—essential to coagulation. In the event that bacteria in the intestines become unbalanced, or taken over by opportunistic organisms such as cholera or amoebic dysentery, the appendix functions to reboot the bacterial flora. Parker explains the mechanism: “Once the bowel contents have left the body, the good bacteria hidden away in the appendix can emerge and repopulate the lining of the intestine before more harmful bacteria can take up residence.”

“Darwin simply didn’t have access to the information we have,” explains Parker. “If Darwin had been aware of the species that have an appendix attached to a large cecum… he probably would not have thought of the appendix as a vestige of evolution.”

When Jerry Coyne (2009), professor at the University of Chicago, writing in his book, Why Evolution is True that “our appendix is simply the remnant of an organ that was critically important to our leaf-eating ancestors, but is of no real value to use,” excluded known evidence. Continued adherence to the vestige status of the appendix by evolutionists requires rejection of the scientific method.

“Maybe it’s time to correct the textbooks,” says William Parker, Ph.D., assistant professor of surgical sciences at Duke and the senior author of the study. “Many biology texts today still refer to the appendix as a ‘vestigial organ.’”  

Jerry Coyne (2009), professor at the University of Chicago, writes in his new book, Why Evolution is True that, “We humans have many vestigial features proving that we evolved. The most popular is the appendix.” Coyne claims that: “our appendix is simply the remnant of an organ that was critically important to our leaf-eating ancestors, but is of no real value to use.”

Coyne believes the expansion of appendix development occurred because of “use” followed by contraction due to “disuse”—the rise and fall of the appendix. Following this belief, one would expect to find the appendix first increasing then decreasing in our presumed human evolutionary ancestors.

The vestige logic is great; unfortunately, the evidence does not support the logic. Coyne, along with the rest of the vestiges adherents fail mention that the rise and fall theory of the appendix simply never happened. The reason: the appendix occurs only in a few diverse mammals—and does not follow an evolutionary continum of rising and falling.

In fact, the appendix, in any form, is not present in any invertebrate. Among the vertebrates, the appendix is absent in fish, amphibians, reptiles, birds, and, most importantly, even in only a few mammals. In fact, the appendix is only present in a few marsupials, including the wombat and South American opossum, a few rodents, including rabbits and rats, and only a few primates, only the anthropoid apes and man. Even monkeys do not have an appendix.

Even though the appendix is “critically important to our leaf-eating ancestors,” tracing the development of the rise and fall of the appendix in presumed human evolutionary ancestors is simply a mirage—nothing more.

Although the Chimpanzee, touted as our closest genetic ancestor, has an appendix, surgeons are not exploring the possibility of any type of Chimpanzee-to-human transplantation and nor is the pharmaceutical industry exploring the use of any Chimpanzee molecules for use in humans, not even insulin.

Insulin and heart valves from the Suidae, the biological family to which pigs and their relatives belong, have long been used in humans. Calcitonin, a polypeptide hormone, is identical to the Calcitonin produced in the species of the fish family known as Salmonidae—Salmon. Why are pigs and the salmon more similar to humans than our closest genetic counterpart?  

The reason is—nature is discontinuous and digital, designed as unique creations. Anatomical and molecular evidence demonstrates that nature is not the result of “slight, successive changes” via mutations as touted by evolution adherents—evidence Jerry Coyne must inconveniently ignore; a practice popularized by Charles Darwin.  

In the final paragraph of the section entitled Rudimentary, Atrophied, and Aborted Organs, Darwin writes: “Finally, the several classes of facts which have been considered in this chapter, seem to me to proclaim so plainly, that the innumerable species, genera and families, with which this world is peopled, are all descended, each within its own class or group, from common parents, and have all been modified in the course of descent, that I should without hesitation adopt this view even if it were unsupported by other facts or arguments.”

The concept of vestiges from the actions of “use and disuse” continues today even though proven to be “unsupported by other facts or arguments.” Little wonder why students continue to question whether science in the classroom today is really science. Even though touted by esteemed college professors, what may be “most popular” can be dead wrong. 

Vestiges  are tauted as evidence for biological evolution based on the Larmarckian concept of “use and disuse” that Charles Darwin reluctantly, yet fully accepted by the 6^th edition of The Origin of Species in 1872.

In the 1^st edition Darwin wrote that“use and disuse seem to have produced some effect” that was later changed to “use and disuse seem to have produced a considerable effect” in the 6^th edition. For Darwin, the importance of “use and disuse” increased from “some effect” to “considerable effect.”

In this series, we are examining the concept that the human appendix is a vestige structure through the process of “disuse.” Vestiges are thought to be biological elements that have lost their function through “disuse.” At issue is—what is the evidence that the process of “disuse” can actually produce vestiges?

In the decade following the publication of the 6^th edition, German biologist August Weismann, at the University of Freiburg, launched the first scientific inquiry to directly challenging Darwin’s theory. Now known as the “Weisman Barrier” in 1883 Weismann cut off the tails of mice from twenty-one generations. Seeing that the twenty-second generation still had tails, Weismann concluded that the evidence contradicted Darwin’s theory of “disuse” and that despite obvious reasons for change in the mice, “continuity” was observed, not new variations.

The concept of the Weismann Barrier became central to the emerging  Modern evolutionary synthesis. “Disuse” alone simply does not result in vestige structures. Ernst Mayr, known as Darwin’s bulldog of the twenty-first century, called Weismann “the second most notable evolutionary theorist of the nineteenth century, after Charles Darwin.”

Evidence from the Weismann Barrier continues to stand unchallenged, now for over 100 years. Even more to the point, after thousands of years of circumcision, “disuse” has failed to any effect on human anatomy. Without scientific experimental evidence demonstrating that “disuse” can result in any biological changes, the concept of vestige as evidence for evolution remains untenetable.

Other known vestige problems for evolution include, 1) the appendix is not found systematically found through nature, even in mammals; 2) “vestige” structures are now known to be functional. These evolutionary contradictions for vestiges continue to undermining evidence for evolution.

In the up-coming posts, we will continue to explore why these last two problems have completely undermined the concept that the human appendix is a vestige structure.

Charles Darwin attempted to avoid the use of the term “vestiges” largely because the term had been associated with the “erroneous” Larmarckian concept of “use and disuse” that was only “veritable rubbish.”

Jean-Baptiste Lamarck (1744 – 1829) was a member of the French Academy of Sciences and was appointed to the Chair of Botany in 1788. When the Muséum national d’Histoire naturelle was founded in 1793, Lamarck was appointed professor of zoology. In 1801, he published Système des animaux sans vertèbres, a major work on the classifications and coined the term invertebrates. Lamarck is thought to be the first use the term biology in its modern sense. Lamarck continued his work as a premier authority on invertebrate zoology.

Darwin did credit “Lamarck as the first man whose conclusions on the subject excited much attention.… In these works he up holds the doctrine that all species, including man, are descended from other species.”

Lamarck’s theory of evolution, which he referred to as “transformism,” was based on the idea that individuals develop new traits during their own lifetimes by “use and disuse” and transmit them to the next generation. Larmack writes – “Progress in complexity of organization exhibits anomalies here and there in the general series of animals, due to the influence of environment and of acquired habits.”

The giraffe served as Lamarck’s classic example of evolution through “use,” acquiring longer necks in successive generations in competition to reach the ever-scarcer leaves higher in the trees. In illustrating Lamarck’s views on adaptation, Darwin wrote, “To this latter agency he seems to attribute all the beautiful adaptations in nature; such as the long neck of the giraffe for browsing on the branches of trees.”

For Darwin, however, this explanation was simply not scientific – “Lamarck, who believed in an innate and inevitable tendency towards perfection in all organic beings, seems to have felt this difficulty so strongly that he was led to suppose that new and simple forms are continually being produced by spontaneous generation. Science has not as yet proved the truth of this belief.”

One of the most eminent pre-Darwinists was Charles Darwin’s own grandfather, Erasmus Darwin (1731–1802). Erasmus discussed his ideas at length in a two-volume work, Zoonomia, published in 1794. Erasmus wrote that “all … have risen from one living filament.”

Erasmus’ book was widely popular in Western Europe- even translated into German, French, and Italian. Erasmus envisioned that the driving force behind species modification was a result of “lust, hunger, and danger.” In line with Greek philosophy, Erasmus envisioned changes by “continuing to improve its own inherent activity.”

Actually how these “improvements” developed was completely unknown to Lamarck and Erasmus—evolution was a philosophy, not a science. The unknown cause of “improvements” is what drove Darwin to discover the underlying laws of nature—scientifically. Writing in the preface of The Origin of Species, Darwin suggests how Erasmus’s work, although “erroneous,” may have influenced Lamarck: “It is curious how largely my grandfather, Dr. Erasmus Darwin, anticipated the views and erroneous grounds of opinion of Lamarck in his Zoonomia.”

For Lamarck, new characteristics are acquired through the process of “use and disuse.” Darwin’s grandfather, Erasmus Darwin, was a Lamarckian evolutionist. Charles Darwin, however, in pursuit of a “scientific theory” of evolution, initially opposed Lamarckian evolution, only granting the theory marginal support.

In a letter written to J. D. Hooker in 1844, Darwin wrote, “Heaven forefend me from Lamarck nonsense of a ‘tendency to progression.’ … But the conclusions I am led to are not widely diff erent from his, though the means of change are wholly so.” “With respect to books on this subject,” Darwin continues, “I do not know any systematic ones, except Lamarck’s, which is veritable rubbish.”

Although attempting to distance himself from Lamarck’s concepts of “use and disuse” and “vestages,” Darwin distain for “use and disuse” eventually waned as causes for the origin of variation required for the actions of natural selection remained Darwin’s largest unsumountable enigma.

Since then, the term, “vestiges” has once again gained prominence over “rudiments,” as has Larmarckian concepts of evolution. The question remains, however, are structures classified as “vestiges” evidence of evolution? Specifically, have vestiges seemingly lost all or most of their original function in a species through evolution?

To address answers to these questions, we will be examining the most popular example of vestiges—the mammalian appendix in the up-coming posts.   

Charles Darwin uses “vestiges” five times in The Origin of Species. Vestiges, since then has become synonomous with evolution. The emenent evolutionist, Douglas Futuyma, Professor of Ecology and Evolutionary Biology at the University of Michigan, notes that vestigial structures make no sense without evolution. The first question is—what are vestiges?

 In this first in a series on vestiges, we will discover how structures labeled as vestiges play an important role as evidence for the theory of evolutionary. Since the most popular example of a vestige structure is the human appendix, the human appendix will be the focus structure examined in this series.

By the time The Origin of Species was published in 1859, vestiges had already been a hot topic popularized by Robert Chambers’ following the publication of the Vestiges of the Natural History of Creation in 1844. The work brought together various ideas of stellar evolution and progressive transmutation of species. The book was a best-seller and is now seen as causing a shift in public opinion that paved the way for the general acceptance of evolution.

While agreeing with the general concept of evolution, Darwin took exception to the concept that evolution occurred by sudden changes in nature. Darwin wrote – “The author apparently believes that organisation progresses by sudden leaps, but that the effects produced by the conditions of life are gradual.”

Perhaps for these differences with Robert Chambers, Darwin even avoided defining the term “vestiges” in the The Origin of Species. In the Glossary, however, Darwin does define a related term: “RUDIMENTARY.—Very imperfectly developed.” In The Origin of Species, the term “rudimentary” appears 101 times.

Darwin envisions rudimentary structures to be the result of two different dynamics: 1) as structures “imperfectly developed”—emerging, and 2) as structures in disuse undergoing loss of function—elimination. Darwin writes – “Rudimentary organs will speak infallibly with respect to the nature of long-lost structures”—a Lamarckian disuse concept. Darwin explains that rudimentary structures exist because “natural selection… had no power to check deviations in their structure.”

Today however, only the elimination due to disuse concept is thought to be in operation. WIKIPEDIA.org states: “Vestigiality describes homologous characters of organisms that have seemingly lost all or most of their original function in a species through evolution. Answers.com defines vestige structures, as “A rudimentary or degenerate, usually nonfunctioning, structure that is the remnant of an organ or part that was fully developed or functioning in a preceding generation or an earlier stage of development.”

The next question is – how well does the human appendix fit the vestige structure criteria? Next week we will examine the existence of the appendix throughout the animal kingdom.
