The Truth About Language

From God to Noam Chomsky, many have suggested that language arose suddenly in a way that cannot be explained through ordinary evolutionary processes. Corballis argues otherwise. He uncovers the precursors of language in the ability of mice and other animals to engage in 'mental time travel', the use of gesture by apes, the capacity of chimpanzees to step into the shoes (or paws) of others, and the increasing need for social co-operation as hominins left the forest. By adding voice and grammar, language enabled humans to take all those capacities up an evolutionary notch. Now we could share stories, we could work collaboratively in groups, and – as different languages became standardised – we could even learn to dislike different groups and different cultures. We were human.
