Detailed explanation-1: -Eunotosaurus, a reptile who lived about 260 million years ago during the Permian period, is the earliest known ancestor of modern turtles. This animal had wide, elongated ribs, but had not developed an actual shell. It was also exclusively land-dwelling and had a full set of teeth.
Detailed explanation-2: -“We show that turtles share a more recent common ancestor with birds and crocodilians-a group known as archosaurs-than with lizards and snakes.”
Detailed explanation-3: -They may not be kissing cousins, but new DNA analysis confirms that turtles share ancestry with birds and crocodiles, according to a recent paper co-authored by an Occidental College biologist.
Detailed explanation-4: -Humans and turtles share a common ancestor What is remarkable is that the basic organisation of the EDC genes is similar in humans and turtles. This leads to the conclusion that the prototypical EDC genes developed in a common ancestor, who lived 310 million years ago and was similar to modern reptiles.
