Very excited to hear this morning about gorillas in the wild being observed using tools for a variety of things. One used a stick to test water depth before stepping in (nice photo here ). That is not just tool use, it is pretty high level thinking, in my opinion. Once again, we are not alone... On a side note, not quite as anthropological, I was also excited to learn this week that a live giant squid has been filmed. Don't think they use tools, but a reminder that quite a bit of science fiction is fact if you look below the waterline is a good thing.
I could tell you how many steps make up the streets rising like stairways, and of the degree of the arcades' curves, and what kind of zinc scales cover the roofs; but I already know this would be the same as telling you nothing. The city does not consist of this, but of relationships between the measurements of its space and the events of its past...A description of Zaira as it is today should contain all Zaira's past. -Italo Calvino, Invisible Cities
