More proof that body language is bomb:

nthropologist Gregory Bateson has noted that our nonverbal communication is still
evolving: "If . . . verbal language were in any sense an evolutionary replacement of communication by
means of kinesics and paralanguage, we would expect the old, predominantly iconic systems to have
undergone conspicuous decay. Clearly they have not. Rather, the kinesics of men have become richer and
more complex, and paralanguage has blossomed side by side with the evolution of verbal language"
