We have often wondered about this question. The heart doesn’t resemble what it is generally shown like. How did it acquire the most commonly used symbol ♥? There must be a reason behind this since the actual heart doesn’t resemble it at all!
In fact, the heart symbol long predates the time that we started to cut open corpses to look at the anatomy of our hearts with any scientific interest. Sure, some tribes were doing it for centuries, but it wasn’t until anatomists like Leonardo Da Vinci that we started to capture the true shape of the human heart so that the public could learn what it looked like. This video by Vox digs an interesting dig at history on how this symbol got popular.
