Human Outer Ears May Have Evolved from Ancient Fish Gills, Study Finds
Human outer ears may have evolved from the cartilage in ancient fish gills, according to recent research. Gene-editing experiments demonstrated a genetic link between fish gills and mammalian ears, with findings suggesting this transformation dates back millions of years. Researchers tested genetic enhancers in zebrafish, mice, and lizards, uncovering evidence that ma...
