Incredible Can we humans be born with a tail? The vestigial tail is an excess that can appear in the lower region of the back, coincidentally resembling the tail of an animal. Hence, the analog phenotype is established compared to the tail of animals. This phenomenon is very strange and very rare in humans, since the seventeenth century more than 100 cases were documented around the world when this human pathology was discovered and analyzed. Really the term Vestigial Tail comes from the similarity of the surplus with the tail of the animals and of vestige, that is to say that it has been only a residue of what the species once was! Then an interesting and extensive debate arises on the evolution of man ("who came first? The chicken or the egg?")
The history of mankind has always focused on theories about evolution, for the most part centered on an origin derived from primates, there are theories that, in ancient times, many aquatic species were forced out of their habitat to settle on dry land. and adapt again to a life out of the water. Any reference to this evolution that has been studied for centuries indicates that both humans and many other animals can preserve some vestiges of our previous version. This type of Queue is a clear example. The Vestigial Tail that appears in humans does not have a bone structure or marrow as can be seen in animals such as: dogs, cats and reptiles that are the closest vestige of what were animals in the past! There are also many other types of recorded vestiges of our prehistoric past. Some of the people studied with "deformations" in the ears, skull or other places of the body have shown a similarity with chimpanzees and other primates.
The vestigial organs to a great extent are part of our organism, they do not have an essential utility for the subsistence of the human being. There are those who speculate the possibility that they had some function in antiquity.
