Continuità, risorgenze, invenzioni? Sui simboli “preistorici” nel folklore contemporaneo
2015
I temi delle continuità culturali e delle “sopravvivenze” sono stati, nel recente passato, al centro del dibattito in ambito antropologico e storico religioso. Ritornano oggi d’attualità in relazione alla questione della patrimonializzazione dei beni immateriali, delle feste religiose “tradizionali” innanzitutto. Gli interrogativi che emergono sia circa l’utilità delle fonti storiche (archeologiche e documentali) ai fini della comprensione della realtà rituale contemporanea, sia rispetto al tema delle continuità cronologiche di pratiche e credenze, meritano infatti, dinanzi alla ormai avvenuta dissoluzione di quella che è stata definita “civiltà contadina” e ai rinnovati interessi verso il …
"Memorie dal sottosuolo". Una prospettiva di indagine sul simbolismo rituale delle feste religiose "tradizionali"
2017
In 1945, writing about the procession of Our Lady of Viggiano, Carlo Levi presents us a peasant world characterized by archaic beliefs and ritual practices, another world « where seasons run on peasant fatigue, [...] like three thousand years before Christ », a world « veiled with black veils, fiery and earthly [...] which you do not enter without a key of magic ». If that other world of the peasants seems to have come to an end today, the beliefs, practices and ritual symbols of reputed “pre-Christian” precedence or in any case alien to the official liturgy, as witnessed by Levi and many other narrators and demoanthropologists from the 19th and 20th century are not, however, definitively l…
Ammonites phylogenetic analysis: state of the art and new prospects
2004
Abstract Two main types of data are available to resolve phylogenies using fossils data: (1) stratigraphic ordering of taxa, and (2) morphological characters. In most phylogenetic studies dealing with ammonites, authors have given priority to the stratigraphic distribution of taxa. This practice is classically justified by the fact that the ammonite fossil record is frequently outstandingly good. In practice, the level of integration of stratigraphic and morphologic information in a single analysis depends on the confidence that authors have in the quality of data. Besides, many evolutionary concepts, which could differ over time and between authors (e.g. anagenesis, cladogenesis, iterative…
Diversification in evolutionary arenas - assessment and synthesis
2019
Abstract Understanding how and why rates of evolutionary diversification vary is a central issue in evolutionary biology and ecology. The concept of adaptive radiation has attracted much interest, but is metaphorical and verbal in nature, making it difficult to quantitatively compare different evolutionary lineages or geographic regions. In addition, the causes of evolutionary stasis are relatively neglected. Here we review the central concepts in the evolutionary diversification literature and bring these together by proposing a general framework for estimating rates of diversification and quantifying their underlying dynamics, which can be applied across clades and regions and across spat…
