Abstract

Spider social species, while being relatively scarce, present a greatdiversity in their organization. The passage to permanent social lifeseems to have occurred several times, quite independently, in distinct lineages. Within these lineages the social forms do not differ from the solitary ones by any marked morphological feature. This suggest that socialization consists basically in behavioural changes, and that these changes are easily produced. The information collected from extant species lead us to attribute such a phenomenom, at first, to certaincharacteristics, already present in solitary species, which can he considered as preadaptations to social life. All spiderlings are gregarious during their first days of living; in maternal species, spiderlings may show an extension of mutual tolerance and social cohesiveness upto an advanced stage. The evolutionary role of these preadaptations may have been amplified by behavioural plasticity, a characteristic found in many extant species. Moreover, the extension of interindividual interactions is likely to have made possible the emergence of cooperative activities, thence increasing the adaptative value of permanent societies.
