Raft-building ants exhibit memory

This is interesting because it was believed brains had to be a certain size to have a certain complexity, which allowed memory.

1. Researchers focused on Formica selysi, an ant species found in floodplains in central and southern Europe.
2. Ants cluster together during floods in order to survive.
3. These ants repeatedly go to the same position when they build a raft with their bodies.

There have been other studies about other social insects, like bees, which show some surprising intelligence also. There are also some bees which generate their own heat! It was thought that no animal except mammals and birds could generate their own heat.
