Yes, you heard right. Although the tail formation Although we think it is unique among animals, it is not impossible to find such a structure in newborn babies.

Without further ado how is such a thing possible Let’s make it clear.

About 40 babies officially reported as of 2017 were born with a tail-like protrusion.

Although this tail formation is actually quite rare, it can be observed up to 18 cm and larger It is a boneless structure that can be easily removed surgically, is very soft and has no function. The world of science has not yet fully solved the mystery of this formation, but researchers, of course, have different views on these extensions.

In fact, the mystery of the origin of human tails begins with Charles Darwin. More than 100 years ago, human tails that evolution is a coincidence On the other hand, Darwin argues that this situation is the remains of a tailed ancestor.

Also in the 1980s, scientists suggested that genetic mutations could occasionally revert to their historical state.

Five years later, he wrote in an article that these unique protrusions, which babies encounter at birth, show two different types of development. The first of these structures is called the “true tail,” while the second is the “false tail,” which may contain bones from time to time. They are called birth defects and are historically associated with birth defects.

In general, these two tail formations are considered harmless, but these protrusions pose a major risk in preventing the development of the embryo in the mother’s womb. Again mixed genetic and environmental factors Among the various theories that may cause this formation.

This peculiar tail-like extension appears when the embryo is about 5 weeks old.

In the 8th week, it integrates with the body of the embryo and therefore the tail will remain until birth, a fairly large congenital defect kind of. Babies born with a tail also face various neurological problems. A 2008 study also states that these extensions are not benign.

To ensure that these babies do not develop health problems in their future lives, the researchers say It is important to have surgery aimed at removing this tail while it is still in its infancy. In addition, he emphasizes that it is very important to pass a brain imaging check.
