This paper provides a minimally simple theory that accounts for the foraging behaviour of animals. It presents three separate systems of differential equations that predict the selection of diets from various types of food, and also the time-budgets

This paper describes a model of the physiology of feeding of a generic seabird. The bird is represented as two types of tissue ‐ structural tissue and reserve tissue ‐ and the ingestion of the food is controlled by a Holling type II functional re

This paper considers a variety of attempts to define fitness in such a way as to defend the theory of evolution by natural selection from the criticism that it is a circular argument. Each of the definitions is shown to be inconsistent with the other

Polymorphism in the cerci of the earwig (Forficula auricularia L.) has been re-examined making use of a graphical method for the analysis of frequency distributions. Three statistically distinct types of male cerci and two statistically distinct type

Optimal foraging theory has nothing to do with the theory of evolution: it has to do with the science of design. The science of design (Simon 1981) can be used to define the optimal strategy for the pursuit of some particular goal in the sense that,

Descartes proposed that animals are really machines, a view accepted by natural theologians who sought to reveal the wisdom of the Deity in the adaptations they discovered in animals and plants. Hume showed that there can be no logically coherent evi

IT has been suggested that environmental fluctuations will limit the degree to which species may be packed; the closeness of the packing increasing with increasing environmental stability1. This theory has been challenged by the suggestion that altho
