The underlying assumption of the aerobic capacity model for the evolution of endothermy is that basal (BMR) and maximal aerobic metabolic rates are phenotypically linked. However. because BMR is largely a function of central organs whereas maximal metabolic output is largely a function of skeletal muscles. the mechanistic underpinnings for their linkage are not obvious. https://chefesquipmenters.shop/product-category/coffee-cups/
