A new study conducted by scientists from China, Sweden, and the United Kingdom reveals that the human middle ear evolved from fish gills.

But where the spiracle came from has puzzled academics for over a century. Chinese scientists have eventually found clues to the mystery in fossils unearthed in the provinces of Zhejiang and Yunnan, which provided anatomical and fossil evidence for the origin of vertebrate spiracles from gills.
