Sociality is a widespread trait in the living world and manifests itself through behaviors such as cooperation and competition. This bibliographical paper offers a comparative analysis of sociality in various taxa, from humans, through other mammals and vertebrates, to organisms lacking a nervous system such as bacteria, molds, and plants. The aim is to promote reflection on the evolutionary complexity of social behaviors, challenging the idea that such behaviors are exclusively linked to the presence of a brain or central nervous system. Instead, the study suggests that sociality may emerge as a shared adaptive strategy, rooted in fundamental biological processes and transversal to multiple domains of life. This approach aims to highlight the continuity and evolutionary convergence of social behaviors, offering a broader and more inclusive view of the phenomenon.
La socialità è un tratto largamente diffuso nel mondo vivente e si manifesta attraverso comportamenti come la cooperazione e la competizione. Questo elaborato, di natura bibliografica, propone un'analisi comparata della socialità in diversi taxa, a partire dall’essere umano, passando per altri mammiferi e vertebrati, fino ad arrivare a organismi privi di sistema nervoso come batteri, muffe e piante. L’obiettivo è promuovere una riflessione sulla complessità evolutiva dei comportamenti sociali, mettendo in discussione l’idea che tali comportamenti siano esclusivamente legati alla presenza di un cervello o di un sistema nervoso centrale. Al contrario, l’indagine suggerisce che la socialità possa emergere come strategia adattativa condivisa, radicata nei processi biologici fondamentali e trasversale a molteplici domini della vita. Questo approccio mira a evidenziare la continuità e la convergenza evolutiva di comportamenti sociali, offrendo una visione più ampia e inclusiva del fenomeno.

Abstract
Sociality is a widespread trait in the living world and manifests itself through behaviors such as cooperation and competition. This bibliographical paper offers a comparative analysis of sociality in various taxa, from humans, through other mammals and vertebrates, to organisms lacking a nervous system such as bacteria, molds, and plants. The aim is to promote reflection on the evolutionary complexity of social behaviors, challenging the idea that such behaviors are exclusively linked to the presence of a brain or central nervous system. Instead, the study suggests that sociality may emerge as a shared adaptive strategy, rooted in fundamental biological processes and transversal to multiple domains of life. This approach aims to highlight the continuity and evolutionary convergence of social behaviors, offering a broader and more inclusive view of the phenomenon.| File | Dimensione | Formato | |
