Nascoste nelle rocce o sotto il sole, di fossili di ragni/ragnatele non ce ne sono. Le storie si dissolvono l'una nell'altra, fanno crollare scale temporali, colmano le distanze. Considera la tua evoluzione multispecie quando disegni il tuo albero genealogico
Hidden in rocks or under the sun, of spider/web fossils there are none. Histories dissolve into each other, collapse scales, bridge distances. Consider your multispecies evolution when drawing your family tree.

Caratteristiche anatomiche: Gli occhi di questo ragno sono disposti su quattro file, molto ravvicinati gli occhi mediani anteriori, sopra i quali e leggermente più distanziati si trovano gli occhi laterali anteriori, poi alle estremità della zona cefalica gli occhi mediano posteriori e ancora più sopra quasi in linea con i laterali anteriori, gli occhi laterali posteriori. Le zampe sono provviste di robusti e lunghi peli sensori. La colorazione tendente al giallo, gli permette di essere poco visibili tra la vegetazione.
Comportamento: Questo ragno è un vero predatore d’agguato, grazie agli occhi laterali anteriori, più grandi degli altri, posti su un piano verticale riesce a mettere bene a fuoco la preda e a lanciarsi su di essa con precisione. Gli altri 6 occhi più piccoli tutti intorno all’area cefalica gli permettono invece di vedere ombre di eventuali predatori, dai quali sfugge lasciandosi cadere.
Anatomical features: The eyes of this spider are arranged in four rows, very close together the anterior median eyes, above which and slightly further apart are the anterior lateral eyes, then at the ends of the cephalic area the posterior median eyes and further above, almost in line with the anterior lateral eyes, the posterior lateral eyes. The legs are provided with strong and long sensory hairs. Its yellowish colouring means it is hardly visible in the vegetation.
Behaviour: This spider is a true ambush predator. Its front side eyes, which are larger than the others, are placed on a vertical plane and allow it to focus on its prey and attack it with precision. The other 6 smaller eyes around the cephalic area allow it to see shadows of possible predators, from which it escapes by falling.
How could anyone ever imagine living things were not social?
How could anyone ever imagine living things were not social? The moment one considers the obviousness of more-than-human sociality, the question of how we could have missed it jumps out. Of course, this is much too big a question to consider properly here, and perhaps the most useful contribution of raising it is to bring many answers to mind in every reader. There are many currents of history that congealed in a social science oblivious to non-humans. Still, there seems to me one small current that is usefully addressed to help us reopen this history. This current is the genealogy of ‘freedom’ as an attribute that separates humans from all other living things. If humans are free, while other species are mechanical toys, then perhaps human sociality is entirely unique. But do other species really lack freedom?
[...]
But, of course, other living beings have ways of life too. Social relations are the forms through which ways of life are organized. They do not have to be organized through conscious direction to be social. [...] Their world-making activities and their freedom to act are also clear—if we allow freedom and world-making to be more than intention and planning. It is from this shared potential of freedom and worldmaking that we can proceed into more-than-human social lives.
