I spy-der

It's that time of the year again. You can't go blackberrying without encountering a spider hanging in the still centre of a web.

Recently the idea of 'extended cognition' has advanced the  hypothesis that spider webs effectively outsource the central brain by interacting directly with the environment, picking up clues and sending back information which  spiders then use to their  advantage  by constructing  webs designed to maximise the potential of their surroundings, rather like the way that our smart phones (if we have them) provide information that may influence our decisions.
