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.
