'Interestingly, marmoset and tamarin babies also babble. It may be that the infants of cooperative breeders are specially equipped to communicate with caretakers. This is not to say that babbling is not an important part of learning to talk, only to question which came first�babbling so as to develop into a talker, or a predisposition to evolve into a talker because among cooperative breeders, babies that babble are better tended and more likely to survive.' Terrence W. Deacon infers that human infants don't even need to be particularly excited or even upset to babble because the fact is that human babies will babble spontaneously and incessantly only when emotionally calm. Deacon adds, 'It is the first sign that human vocal motor output is at least part
