Why do some people’s ears stick out more than others?
Quick Answer
Ear shape is mostly determined before birth by genetics and the way cartilage develops. Small differences in the folds of the outer ear can make ears lie close to the head or protrude more.
The Full Story
The outer ear, or pinna, is made largely of cartilage that forms in the womb. Genetic variation influences how the ear’s folds and ridges develop, which is why ear shape differs so much among people. If the cartilage folds are less pronounced, the ears may stick out more. This is usually just a normal variation in anatomy, not a health problem. In some cases, ear shape can also be influenced by inherited syndromes or minor developmental differences.
