Abstract
Contrary to previous widespread belief, the small intestine possesses only a modest excess of nutrient absorptive capacity over nutrient intake. This problem exemplifies a field that is now emerging at the infrace between physiology and evolutionary biology and that is concerned with the relation between evolved capacities and natural loads of physiological systems.Keywords
