Abstract
An increase or decrease in size could not evolve without extensive rescaling of many physiological, morphological, and developmental variables. Although a 2.2 kg bird could have descended from smaller of larger birds, chances of her laying 400 g eggs would be unlikely without Large (∽13 kg) ancestors on a predator-free island.Keywords
