It’s evolutionary biology. In a fascinating new discovery, scientists have found evidence suggesting that the flexible outer part of human ears may have evolved from the gills of ancient fish.

Think about how cats, dogs and certain monkeys twitch their ears in response to new sounds. This instinctive movement isn't just for show; it helps funnel sound toward the animals' eardrums ...

Research links human outer ears to cartilage in fish gills. Gene-editing experiments confirm evolutionary connection. Findings date back to marine invertebrates 400 million years ago.

Published in Nature by researchers at the Keck School of Medicine of USC, the study connects the elastic cartilage in mammalian ears to the same rare tissue found in fish gills. To explore this link, ...

LOS ANGELES — Scientists have made a groundbreaking discovery about the origins of the human outer ear, revealing that this distinctive mammalian feature evolved from an unexpected source: fish gills.

“If we can engineer an ear, that would be a better approach.” Spector’s team used 3D printing to create an anatomically accurate template of a human ear from polylactic acid bioink, a biocompatible ...

Biomechanical studies confirmed the replicas’ flexibility and elasticity similar to human ear cartilage, although they were not as strong and could tear. To enhance strength, researchers plan to ...

Pictured is the intricate, left-ear plastic scaffold that was created on a 3D printer based on data from a person’s ear, anterior view (left) and posterior view (right). Researchers have created ...
