It’s strongly theorized that turtle ancestors went from land to sea and then back to land. However, it’s tough to completely pin down because turtles have a very bizarre evolutionary history. For example there are proto turtles with shells but without beaks but also proto turtles with beaks but without shells suggesting that either beaks or shells evolved twice and one of those lines died out. |
