According to the cladogram, which animal is most primi ve?
Which animal evolved first, crocodiles or turtles?
Which animals would be more closely related? Birds and lizards/snakes OR birds and turtles.
What trait do the amphibians not share with any other animal on the cladogram?
Which trait evolved first: live birth or opening in the skull for muscles?
