Fossili di insetti preistorici giganti che conservano ancora intatti i muscoli delle zampe e parti del sistema nervoso dopo 240 milioni di anni sono stati rinvenuti sul Monte San Giorgio, al confine tra Ticino e Italia.
Uno studio in merito è stato pubblicato su Scientific Reports dall'Università Statale di Milano in collaborazione con l'Università Ludwig Maximillian di Monaco.
Questi animali vissuti nel Triassico potevano raggiungere gli otto centimetri di lunghezza. Nati dopo una grave crisi delle forme di vita sulla Terra, confermano che l'evoluzione procede a balzi, con brevi periodi di cambiamento seguiti da lunghi periodi di stasi.
