The first clue toward cracking this mystery was the team's discovery that gills and outer ears are both composed of a relatively rare tissue type: elastic cartilage. "When we started the study ...

Here’s how it works. Humans' outer ears may have evolved from the gills of prehistoric fish, a new study finds. Gene-editing experiments indicate that cartilage in fish gills migrated into the ...

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 ...

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.

The first clue toward cracking this mystery was the team's discovery that gills and outer ears are both composed of a relatively rare tissue type: elastic cartilage. "When we started the study ...

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 ...

Scientists have long wondered about the evolutionary origins of outer ... the novel cartilage by chance, while getting ready to look at mouse ear tissue under a microscope. After using chemicals ...

Humans' outer ears may have evolved from the gills of prehistoric fish, a new study finds. Gene-editing experiments indicate that cartilage in fish gills migrated into the ear canal millions of ...

Unlike bones, which can fossilize and provide clear evidence of evolutionary changes, the outer ear consists primarily of elastic cartilage – a flexible, specialized tissue that rarely preserves in ...

The outer ear is unique to mammals, but its evolutionary origin has remained a mystery. According to a new study published in Nature from the USC Stem Cell lab of Gage Crump, this intricate coil of ...
