Oh wow, that's cool! Is the urge to breathe in humans instinctual or is there a chemical signal that pushes us to after a certain amount of CO2 builds up in our bodies? If we had the physiological adaptations of a whale (the blood and muscle oxygen storage) would we still experience a push to breathe before we reached an unsafe blood CO2 level or would we be able to go longer because of that increased oxygen retention?
