Summary
Without language, social interaction would be impoverished beyond recognition. It enables us to reveal our innermost thoughts to others, or, if the mood takes us, to disguise them with misinformation and lies. With language, action can be coordinated so that a group of people can act as one – even if chimpanzees could conceive of a pyramid they still couldn’t build one because they lack the ability to coordinate action through language. Language also, as we shall see in Chapter 14, enables hard-won knowledge to be passed on to others – including our children – enabling culture to proliferate in ways that would not have been possible in our languageless ancestors (in fact, as we shall see, one theory proposes that language evolve to facilitate cultural transmission). When language evolved it was evolutionary dynamite. Not only did it vastly extend the range of things that ancestral humans were capable of, enabling them, perhaps, to outcompete other hominins around at the time, but it is also likely to have had an impact on the evolution of the brain itself. It is unlikely that our languageless ancestors had brains identical to ours but lacking the appropriate language circuitry; it is more likely that the gradual evolution of communicative sophistication led to huge leaps in the way that we interact with others. So great are the advantages of language to our species that surely it must have been the product of natural (or sexual) selection.
