Abstract
The authors provide an historical account, as well as suggestions for the future, regarding the study of communication from a biological perspective. They claim that the study of "speech" has always had a biological element in it. In today's research, they focus on the work of four sets of researchers, including the communibiological perspective of McCroskey and Beatty, the communication gene approach of Buck, the endocrine method of Floyd, and the biosocial approach of Hickson and Stacks. While indicating that the four views are different, they encourage trying to pull the research together. They also encourage all communication researchers to begin investigating the biological approach.
