The Evolutionary Connection Between Human Facial Structure and Fish

Dr. Michael Mosley explains the evolutionary links between human facial development and fish. He notes that during embryonic development, the human face begins to form in ways that resemble the structure of fish. This process is visible in how features like the nose and lips align and fuse. The expert highlights that these developmental stages are evidence of human evolution from aquatic ancestors. Failure in this complex developmental process can sometimes lead to birth defects like cleft lip or palate.
