summary

This article challenges the commonly held belief that the evolution of the turtle shell was primarily for defense. It argues that the shell actually evolved as an adaptation for digging, rather than protection from predators. The author examines the evidence from fossil records and comparative anatomy to support this claim. The article suggests that the ancestors of turtles were burrowers, and the development of a sturdy shell allowed them to efficiently dig and maneuver through loose soil. This alternative explanation for the evolution of the turtle shell provides a new perspective on the adaptive value of this unique anatomical feature.
