This paper is divided into two parts: classic knowledge on theory of island biogeography I and the evolution of behaviour and morphology under insular constraints II.

The main subjects dealt with are: the problem of small populations 1; the biological definition of an island and the importance of biological studies on islands 2; the species-area effect and its consequences for a nature conservation strategy 3; the equilibrium theory and the weaknesses of this model 4; the founder principle 5; some features of insular populations, such as clutch size, niche enlargement and changes in body size 6; the natural history of colonisation and the success and failure of colonisation 7; the morphological paradigm of island faunas 8 and the evolution of social behaviour under insular constraints – territoriality, altruism, social structure and its relationships with body shape 9.
