The pink remnant in your eye is a relic of evolution
In short: That small pink structure in the corner of your eye is actually a vestigial third eyelid. Dorsa Amir explores why our bodies carry these evolutionary leftovers that no longer serve their original purpose.
The video examines the concept of vestigial organs—body parts inherited from ancestors that have lost their primary function. Using the human third eyelid as a central example, the lesson investigates how natural selection and evolution allow these remnants to persist in the human body across generations.
