Optimal Organism Design and Costs for Not Being Perfect
Optimal means the best, but organisms often solve multiple problems so any one problem is not solved best. An optimal function is produced for sugar ingestion rates versus sucrose concentration through butterfly proboscides and pipets by humans. A choice experiment is performed using probing by a butterfly proboscis toward one of two concentrations of sucrose. A non-optimal system is then studied: cylindrical container designs by businesses where surface area (cost) is least when height equals d
