The human appendix was once considered to be a Biological ‘Remnant’, a useless evolutionary artefact, that had lost all its function (or atleast all of its important function). Many Darwinists regarded this as evidence for macro-evolution.
However latest research shows that appendix performs important immune functions. Loren G. Martin, professor of physiology at Oklahoma State University, in his reply to the question, What is the function of the human appendix? Did it once have a purpose that has since been lost? states that
We now know, however, that the appendix serves an important role in the fetus and in young adults.
He explains its role in the fetus
Endocrine cells appear in the appendix of the human fetus at around the 11th week of development. These endocrine cells of the fetal appendix have been shown to produce various biogenic amines and peptide hormones, compounds that assist with various biological control (homeostatic) mechanisms.
Loren G. Martin, shows that “Among adult humans, the appendix is now thought to be involved primarily in immune functions.” He says
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.
Not only that, Loren G. Martin, points out 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” and “helps to suppress potentially destructive humoral (blood- and lymph-borne) antibody responses while promoting local immunity”. It is also “regarded as an important ‘back-up’ that can be used in a variety of reconstructive surgical techniques”
William Parker, PhD, assistant professor of surgical sciences at Duke, reflects on the latest findings. “Maybe it’s time to correct the textbooks,” he says “Many biology texts today still refer to the appendix as a ‘vestigial organ.'”
Thus we conclude that the contention that the human appendix is a vestigial organ and thus provides evidence for macro-evolution is a myth of the past. Latest Scientific research shows that appendix performs important immune functions.
