Research on how bacteria adapt to changing environments underlies the
contemporary biological understanding of signal transduction (ST), and ST
provides the foundation of the information-processing approach that is the
hallmark of the 'cognitive revolution,' which began in the mid-20th century. Yet
cognitive scientists largely remain oblivious to research into microbial behavior
that might provide insights into problems in their own domains, while
microbiologists seem equally unaware of the potential importance of their work to
understanding cognitive capacities in multicellular organisms, including
vertebrates. Evidence in bacteria for capacities encompassed by the concept of
cognition is reviewed. Parallels exist not only at the heuristic level of
functional analogue, but also at the level of molecular mechanism, evolution and
ecology, which is where fruitful cross-fertilization among disciplines might be
found.
