They would argue, much like the vestigial organ argument, that there were upwards of 90% of the DNA that was vestigial, or useless. I would argue that the supposed vestigial organs were in fact useful, and the argument for JunkDNA was an argument from silence … much like the 180 vestigial organ list of the late 1800’s was.

Female mammary glands are never fully developed and functional except during times of breast feeding the young. This vestigial organ argument was first discussed in some detail by Charles Darwin in The Origin of Species in a chapter section titled Rudimentary Organs. The term rudimentary means that these organs are atrophied relics of what they once were in our supposed animal ancestors. Darwin spent several paragraphs defending his idea that they are The last section of this chapter, labeled "Rudimentary Organs" addresses the vestigial structures in animals, and it shows that only natural selection can account for these features. Darwin defines vestigial structures as structures that persist within a species but have lost their function. They claimed that vestigial or diminishingly useful organs, which Charles Darwin called rudimentary, proved that bodies had evolved from more primitive forms.

Rudimentary organs vs vestigial organs

Vestigial organs are those structures in the body that have lost its function and reduced structure and also called rudimentary structures. These structures though may have lost the salient function but may have retained some residual function. The male mammary gland is clearly a rudimentary or vestigial structure, but even the mammary gland of the nonlactating female might be considered vestigial. Female mammary glands are never fully developed and functional except during times of breast feeding the young. This vestigial organ argument was first discussed in some detail by Charles Darwin in The Origin of Species in a chapter section titled Rudimentary Organs. The term rudimentary means that these organs are atrophied relics of what they once were in our supposed animal ancestors.

Darwin defines vestigial structures as structures that persist within a species but have lost their function. They claimed that vestigial or diminishingly useful organs, which Charles Darwin called rudimentary, proved that bodies had evolved from more primitive forms. However, research has shown the supposed vestigial organs or structures of the human body—such as the appendix, the tonsils and the tailbone—are not "vestigial" at all, but rather are quite useful and purposeful body structures. Although structures called vestigial often appear functionless, a vestigial structure may retain lesser functions or develop minor new ones.
