Darwin's Tubercle Facts, Myths, Benefits, Removal

Darwin’s Point also called “Darwin’s Tubercle” or “Darwin’s Bump” is a small bump on the outside of the ear that Darwin used to try to show that evolution happened. The most frequent way to define Darwin’s tubercle is as a bulge on the superior part of the helix. Darwin’s Point gets its name because Charles Darwin first proposed using the fact that some primates, such as baboons and macaques, have a point at the tip of their ears as evidence that humans share a common ancestry with these animals in his book The Descent of Man. Darwin’s tubercle is an unusual helical growth that is completely harmless. 

The identification of Darwin’s Point is tricky since it is so varied in location and size that it might be situated in virtually any location in the approximate area where Darwin described it, even though it was barely distinguishable on the auricle helix of the ear.

Darwin’s tubercle is a birth defect of the ear that causes the helical rim to stick out or thicken abnormally. This is often found where the middle and top third of the helical rim meet. Charles Darwin gave the anomaly its name after describing this discovery in his books as proof of the evolutionary resemblance between primates. 

Darwin’s Tubercle Facts

A key issue is that our presumed closest ancestors, the chimpanzees and the majority of other higher apes, lack both a pointed ear and a Darwin’s Point.  Yellow baboons and Macaques are among the few monkeys with pointed ears. There are no descriptions or illustrations in the literature that show a chimpanzee’s ear with a characteristic like Darwin’s Tubercle. Gorillas, orangutans, gibbons, and the diminutive chimpanzees known as bonobos do not have pointed ears either. The Darwin’s Point trait is more strongly influenced by early developmental circumstances in the womb than it is by genetics, or even not at all, which poses a serious challenge to the atavistic view. 

Darwin’s Point is a characteristic of the embryonic ear that is thought to form due to an uneven inward twisting of the helix. The precise developmental factors that cause Darwin’s Point remain unknown. In other words, it is a benign congenital quirk that develops from a small deformity induced by the folding of the ear during early development. This abnormality is what leads to the ear having a lopsided appearance.

Darwin’s Tubercle Myths

Some individuals possess a little bulge inside their upper ear. Charles Darwin discussed this in his book “The Descent of Man,” hence the name “Darwin’s tubercle” or “Darwin’s bump” has stuck ever since (Darwin 1879). Darwin’s tubercle is occasionally used to illustrate fundamental genetics; the fallacy is that it is regulated by a single gene with two alleles, one of which is dominant. 

Darwin’s Tubercle Benefits

In terms of forensic science, Darwin’s tubercle is viewed as a characteristic that adds to the distinctiveness of the human ear. Darwin’s tubercle is an unusual helical growth that is completely harmless. Numerous research has proposed that the uniqueness of each individual’s ear could be used for personal identification. Some people have also stated that in the future if there is enough variation, ear prints might be utilized in courtrooms. Darwin’s tubercle, with its diverse manifestations, unquestionably adds to the individuality of each human ear and is useful for such purposes.

Darwin’s Tubercle Removal

Darwin’s tubercle surgery includes modifying the helical rim to remove the additional, undesired section of cartilage. The prominence in the cartilage needs to be shown first. The incision is often concealed within the helical rim’s inner lining. When the skin is pushed back, the extra cartilage that makes up Darwin’s tubercle is visible.  After that, precise cuts are made to the cartilage. The new form and contours become immediately apparent after the skin has been redraped.
