Rare Features
Did you know that you may have a rare body feature without even realizing it? One such feature is a cervical rib, which is an extra rib that appears above the first rib, near the base of the neck. Only one in 200 people have this rare extra rib, and it is usually harmless. In the rare case that it causes pain, it can be safely removed. Another interesting feature is heterochromia, where a person has different colored eyes. This can be complete, with two completely different colored eyes, or partial, with only a portion of the eye being a different color. Heterochromia can be present from birth or acquired after an injury. It is a rare condition, with less than 200,000 people diagnosed with it in the U.S. Eye color can also be rare, with gray eyes being less than 1% of the population. Gray eyes are caused by a lower level of melanin in the eye’s layers. Another rare ability is tetrachromacy, where some individuals have four types of cones in their eyes, allowing them to see a wider range of colors. This condition is believed to only affect women. Additionally, around 2% of people are born with a bifid uvula, which means that their uvula is split or forked. While this can cause difficulties with eating, drinking, and speaking, it’s really an interesting feature to know
