New research puts a fresh spin on current thinking of speech evolution in humans

A study, published today in the prestigious journal Nature by Dr. Michael Petrides and colleagues at the Montreal Neurological Institute (MNI) at McGill University, challenges current thinking that speech developed as a result of new structures that evolved in the human brain. Dr. Petrides and coll...
