Origini, specie e individui di fronte al divenire dei processi biologici

Alessandro Minelli

Abstract


Because of the steady involvement of organisms in evolutionary dynamics, of the frequent occurrence of uniparental reproduction and of the diverse outcome of hybridisation events, the species category does not easily apply to a sizeable part of the living world. Problematic is also often the use of the category of the individual, especially in the case of polyembryony, and the distinction between metamorphosis of the individual and metagenesis (alternation of generations) is also often uncertain. More generally, fixing origins is commonly arbitrary, in respect to phylogeny (‘origin’ of species) and ontogeny (‘origin’ of individual) alike.

Keywords
