In an effort to replicate an experiment conducted over a century ago, researchers present evidence confirming at least one single-cell organism -- the trumpet-shaped Stentor roeselii -- exhibits a hierarchy of avoidance behaviors. Exposed repeatedly to the same stimulation, the organism can in effec...
