L'origine come materia comune
2012
The Origin Seen as Common Matter Twentieth-century theories of form and organic form show a hard ten- sion between the idea of the origin as appropriative dynamics – in which the dynamic element refers to a metaphysics of force, and the form-centring is just defined as appropriation – and the idea of the origin as a ‘common matter’. The essay explains these two theoretical options discussing these opposite polarities in biology and analysing some cinematic examples taken from Ejzenštejn’s thought on Disney’s Silly Symphonies.
Flexible parental care: Uniparental incubation in biparentally incubating shorebirds
2017
The relative investment of females and males into parental care might depend on the population’s adult sex-ratio. For example, all else being equal, males should be the more caring sex if the sex-ratio is male biased. Whether such outcomes are evolutionary fixed (i.e. related to the species’ typical sex-ratio) or whether they arise through flexible responses of individuals to the current population sex-ratio remains unclear. Nevertheless, a flexible response might be limited by the evolutionary history of the species, because one sex may have lost the ability to care or because a single parent cannot successfully raise the brood. Here, we demonstrate that after the disappearance of one pare…
Fra Terrence Deacon e la biologia teoretica: l’origine della facoltà estetica e la questione del gioco
2014
Based on a comparison between the contemporary evolutionary perspective supported, among others, by Terrence Deacon, and the biotheoretical thinking of early twentieth-century Germany, this paper purports to contribute to the debate on the origin of the aesthetic faculty, enhancing the role of morphology and the question of play, meant as an exemplary manifestation of the interaction between individuals and environments.
Predictors of enhancing human physical attractiveness: Data from 93 countries
2022
People across the world and throughout history have gone to great lengths to enhance their physical appearance. Evolutionary psychologists and ethologists have largely attempted to explain this phenomenon via mating preferences and strategies. Here, we test one of the most popular evolutionary hypotheses for beauty-enhancing behaviors, drawn from mating market and parasite stress perspectives, in a large cross-cultural sample. We also test hypotheses drawn from other influential and non-mutually exclusive theoretical frameworks, from biosocial role theory to a cultural media perspective. Survey data from 93,158 human participants across 93 countries provide evidence that behaviors such as a…
