Why does a more upright posture (i.e., limbs more under the body) in therapsids indicate a higher metabolic rate?
What will be an ideal response?
With a more upright posture, animals were able to run and breathe at the same time?that is, to have sustained activity. But sustained activity also depends on a higher metabolic rate. If therapsids had the anatomy indicative of a greater degree of sustained activity, then it is likely that they also had the physiology to support that activity.
