Plant Studies May Lead Us to Rethink the Concept of Behavior

David Stenhouse’s classical definition of intelligence as “adaptively variable behavior within the lifetime of the individual” (Stenhouse, 1974, in Trewavas, 2003), widely accepted among biologists, explicitly refers to behavior, requiring thus a previous understanding of this concept. Here, we are providing a biologists’ perspective, which may differ from that of psychologists, economists or cognitive scientists, in hope that we may prompt colleagues from those fields to participate in quest for a common language.
