Have you ever wondered why human ears are built the way they are, and how they came to be? Science has yet to fully uncover ...

Our ears used to be gills? The outer ear, specifically. That’s the news from a new USC Stem Cell st ... “We had been studying ...

By comparing how the same gene control elements can drive development of gills and outer ears, ... Repurposing of a gill gene regulatory program for outer ear evolution. Nature, 2025; DOI: 10.1038 ...

Otitis externa, the most common one that typically affects the outer portion of the ear Otitis media, affecting the middle part of the ear canal and usually a secondary development in up to 50% of ...

External ear anomalies can thus serve as visible markers for vascular variations that might increase disease risk. Beyond embryonic development, ongoing cellular processes throughout life connect ...

Two new studies offer insights into the evolution and development of external ears, which appear in humans and other mammals but aren't found in reptiles, birds or amphibians ...

Evolution is a master recycler. It often uses old structures (or ancient genes) for new jobs. The mammalian ear is a perfect example. Over the eons, the jawbones of our fish ancestors became three ...

Gene-editing experiments indicate that cartilage in fish gills migrated into the ear canal millions of years ago during the course of our evolution.Going even further back, our outer ears may have ...

A University of Florida study found that early ear infections in children could have a long-term impact on speech development. The lead researcher and a pediatric otolaryngologist break down the ...
