      If they had basic spatial cognition, they would not have needed that bridge. Good example of the emergent intelligence of groups instead of cohesive individual minds? https://twitter.com/boni_bo/status/1026067216360501248 …

      I read they need the bridge because they’re unable to carry wasp larvae home if they walk directly along the ceiling. But carrying down and back up is OK.

      If they had intelligence (= ability to build models) they could easily shorten the bridge, thereby freeing bridge building ants for foraging, but their evolved algorithm is too primitive for that.

      Maybe some practical reason the bridge has that shape? It looks like it might minimize stress/load of each bridge ant or on the connecting points

      Nah, the longer the bridge the more stress. The algorithm probably just days: as long as others walk on you, stay in the bridge; as soon as a gap emerges, fill the gap.

      Simple algorithm doesn't mean stupid. Given that these ants optimize bridge material vs path length in other experiments I'd expect there to be some benefit in this costly structure. Something something tension. I found a nice picture.pic.twitter.com/migRCuKaSV

      Of course, yet the bridge in the video was a wasteful solution. I understand the desire to romanticize insect cognition, but come on

          How else could they have built this bridge? They basically can just hang from both sides. Apparently they can not 'swing' and knot the ends together, could they? So they need longer lines until it is possible to reach the other side, I think.

          I suspect you give them too much credit: they don’t have communication or spatial models, so they did not start building from two sides. They probably just crawled on each other, slipped away from the ceiling and then kept elongating the bridge to account for additional slippage.
