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.
plays a crucial role in understanding the design and functionality of the human ear. Recent research has focused on various aspects of ear morphology, including the geometry of ear canals ...
To test whether enhancer activity — and therefore gene regulation — is similar in fish gills and human outer ears, Crump and his colleagues inserted human outer ear enhancers into zebrafish ...
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, ...
It turns out the human ear got off to a fishy start. Literally. A fascinating new study reveals that the mammalian outer ear has its evolutionary roots in the gills of ancient fish. This ...
