So did we evolve and now have lungs or are we evolving to not have lungs? That, is the question. :smile:

He's not exactly the most handsome fellow :laugh: but could we way ahead of the rest of use 4 legged creatures in an efficient way to get it's oxygen requirements. Thanks for posting the link. I actually never realized that there were any 4-legged critters without lungs (I didn't know that salamanders didn't have lungs either).
