Vestigial Tail


The vestigial tail is an excess that appears in the lower part of the back of people, its elongated shape resembles the tail of an animal, hence the analog phenotype is established compared to the tail of animals. This phenomenon is very strange, very uncommon, in fact there are 100 documented cases around the world since the 17th century when this human pathology was discovered and analyzed. The term Vestigial Tail comes from the similarity of the surplus with the tail of animals and vestigial, that is to say that it is nothing more than a residue of what the species once was, here an interesting debate on the evolution of man originates.

The history of humanity has always focused on an origin derived from the primates, in which the conditions of the earth at that time forced the species to come to the surface (those that were in the water) and adapt to a life in the earth. All the reference of this evolution that has been studied for centuries, indicates that the human being and many animals can preserve some traces of their previous version. This type of queue is a good example of this. The vestigial tail that appears in humans does not have a bone structure or marrow as seen in animals such as dogs, cats and reptiles, which are the closest vestige to what animals were in the past. There are also other types of vestiges of our prehistoric past, some patients studied with deformities in the ears and skull have shown a similarity to chimpanzees and monkeys.

The vestigial organs, on the other hand, are parts of our organism that do not have an essential use for the subsistence of the human being, but that in ancient times may have been useful, an example of this type of organ is the appendix, which is no more that an extra part of the small intestine that perhaps served our herbivorous ancestors. The coccyx is also a section of the spinal cord that is extra in the human body, which surely in evolution was sectioned in this way, leaving a portion in the body.
