Story summary

A groundbreaking discovery by USC scientists reveals that our outer ear evolved from fish gills, thanks to elastic cartilage. By examining gene control elements known as enhancers, researchers found these elements active in both zebrafish gills and mammalian ears. This insight sheds light on the remarkable adaptability of structures through evolution, enhancing our understanding of ear development.
