1 Cells must communicate to coordinate their activities. 2  Communication between cells is also important for many unicellular organisms. 3  Biologists have discovered universal mechanisms of cellular regulation involving the same small set of cell-signaling mechanisms. Communication between cells is also important for many unicellular organisms. 2  Biologists have discovered universal mechanisms of cellular regulation involving the same small set of cell-signaling mechanisms. 3  The ubiquity of these mechanisms provides additional evidence for the evolutionary relatedness of all life.
