You need to explain to your study group why the breathing ability of amniotes is different than that of amphibians. Your classmates argue that something like a terrestrial salamander is identical in its breathing mechanism to an amniote. To convince them of the critical breathing innovations of amniotes, you report that in order to breathe as an amniote does, the terrestrial salamander would have to

grow scales on its body

develop new musculature associations in the ribcage

grow lungs

reduce the size of its mouth

In order to breathe as an amniote does, the terrestrial salamander would have to  develop new musculature associations in the ribcage.

It might utilize, skin, gills or lungs for the procedure of breath, though amniotes only breath through lungs.
