Tiny little hole, looks like a piercing but it’s in a place you would never actually pierce?
Ear pits occur in Just 0.1 percent of the population in the US, 0.9 percent in the UK, and 4 to 10 percent in Asia and parts of Africa, according to this study
Preauricular sinus is a congenital disorder and even though harmless in itself, it can be susceptible to infection because… well it’s a tiny hole for bugs to enter your ear.
Signs of an infection include:
- swelling in and around the pit
- fluid or pus drainage from the pit
Neil Shubin, an evolutionary biologist, paleontologist, and popular science writer hypothesizes that the holes “could be evolutionary remnant of fish gills.”
Shubin wrote “Your Inner Fish: A Journey into the 3.5-Billion-Year History of the Human Body,” and it was named Best Book of the Year by the National Academy of Sciences
Ear pits are caused by the first and second pharyngeal arches. This is a structure found in all vertebrates that occurs during embryonic development. In mammals, they go on to form the structures of the head and neck, but in fish, they also help develop into their gills. – IFL SCIENCE
So according to science your ear pit a living proof of the long way humans had to go through to get where we are today, from a single-cell organism to fish and to homosapiens
What do you think of his hypothesis?
