How the Turtle Got Its Shell

The video explores the evolution of turtles, starting with the discovery of Proganochelys, the oldest known turtle. It delves into the debate over turtle ancestry, discussing whether turtles belong to the clade Para reptilia or Eu reptilia. Developmental biology provides insights into shell evolution, suggesting that the plastron evolved before the carapace. Fossil discoveries, such as Odontochelys and Eunotosaurus, offer evidence supporting these theories. The video concludes with theories on why turtles developed shells, highlighting adaptations for burrowing and protection.
