The axiomatic theory presented in Galleni and Forti [1999], being part of the foundational programme of Ennio De Giorgi, is based on the fundamental notions of quality, relation, operation and collection, and provides a very general axiomatization of the biological notions of living object, generation, species and speciation. Within this theoretical framework we consider here a difficult case of classification of species: the Callithrix jacchus group of the New World monkeys. Although the morphological analysis strongly suggests the individuation of six different species, nevertheless several experiments of crossing give evidence to fertility of hybrids. Since both the morphological and the hybridological criteria have shown to be of enormous importance in actual classification of species, this apparent contradiction seems very disappointing. Our axiomatization of speciation processes as operations acting in special time intervals permits to avoid the contradiction by allowing for i...

In 1513 the famous Turkish navigator, geographer and cartographer, the admiral Pîrî Reis, drew a large planisphere showing the entire known world of the time. Today only a fragment of this work remains, conserved at the Topkapi Sarayi Museum in Istanbul (Turkey) and referred to as the Carte de l'Atlantique. This map represents one of the most controversial, mysterious and beautiful documents in the history of cartography. The aim of this study is to analyse the zoomorphic representations of the Pîrî Reis map, investigating the sources of their iconography as well as focusing on their zoological and cultural meanings. We carried out a review of existing literature on this topic, attempting to provide an updated scientific interpretation of the animals portrayed, considering the zoological knowledge assumed to exist at the beginning of the 16 th century and the probable cultural background of Pîrî Reis. Our interpretation demonstrates that many of the animals represented in the Pîrî Reis map conform to the European and Near-Eastern late medieval iconographic tradition. On the other hand, other zoomorphic representations, such as Caribbean parrots, appear unrelated to any previous source and could possibly have been copied from Columbus' lost map.
