Umm, we mammals have a sustained high metabolic rate without avian
All I would say one can conclude from a lack of avian-type lungs is
the metabolism was not yet as high as in living birds!
May the peace of God be with you.
Yes, and one mode is lean muscle mass (don't mean to sound like a
Joe Weider advertisement!).
Mammals can increase metabolism by increasing muscular mass (vs) fat
tissue. But, muscle weighs
more than fat, so added muscle mass beyond a given weight isn't
really an option in a bird that flies.
In general, there are different metabolism strategies. So, I
tend to agree with you.
