Why do some people have attached earlobes?
Quick Answer
Attached earlobes are a normal inherited variation in ear shape. They occur when the lower earlobe joins the side of the face more directly instead of hanging free.
The Full Story
Human earlobe shape varies widely, and attached earlobes are one common form. The trait is influenced by genetics, but it is not a strict single-gene switch because family traits can blend in different ways. Earlobes develop from tissue growth in the embryo, and small differences in that growth can create attached, partially attached, or free earlobes. The variation has no known health effect and is mainly a cosmetic difference.
