The Full Story
The egg tooth, a small temporary structure used by chicks and other hatchlings to break out of the shell, was described by scientists in the 19th century. As embryology and comparative anatomy developed, researchers studied how birds emerge from eggs. The egg tooth is a brief but crucial adaptation in many bird species. It usually falls off soon after hatching, making it one of the most temporary structures in the bird life cycle.
