Scientists call this a “neural fossil”, a leftover trait from our evolutionary past that refuses to fade away. Yet, despite being functionally obsolete, the muscles around the human ear—the auricular ...
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.
Human ears try to move while listening to a sound, a recent study by Saarland University in Germany has revealed. Movement of ears is a common trait in animals, which not only help them focus on a ...
Andreas Schroer, the lead researcher from Saarland University in Germany, explained that it's thought our ancestors lost the ability to move their ears around 25 million years ago. However, it's hard ...
