What did a turtle evolve from? The DNA hypothesis suggests that turtles were a sister group to the archosaurs (the group that contains the dinosaurs and their relatives, including crocodiles and their ancestors and modern birds and their ancestors). A second hypothesis posits that turtles were more closely related to lizards and tuataras.

What animal poops out of mouth?
In 1880, the German zoologist Carl Chun suggested a pair of tiny pores opposite the comb jelly mouth might secrete some substance, but he also confirmed that the animals defecate through their mouths. In 1997, biologists again observed indigestible matter exiting the comb jelly mouth—not the mysterious pores.
Do turtles fart?
Tortoises and turtles do fart! Farts can range in size and sound just like humans.
