New fossil evidence from roughly 380 million years ago suggests the neck first arose as early fish-like vertebrates gained the ability to move their heads independently of their bodies. Researchers say this development is tied to the eventual transition onto land, and paleontologists are comparing skull and shoulder structures across species to trace how the arrangement evolved.

Why now: New paleontological findings about the evolutionary origin of the neck are drawing attention
