When did language originate? It’s a tricky question to answer. We can’t go back in time. We can’t even look at “fossilized brains” to see how they worked. So how can we understand the origins of language?
Scientists have a few ways to do this. One way is to scan the brains of living animals – humans, chimpanzees, apes, and monkeys. They can see how these brains work, how they are different than ours, and how they are the same. Using this, they can infer some of our own evolutionary history.
Many people previously thought the origins of language went back about five million years. But now, a team of scientists are suggesting that pre-language ability actually went back much, much farther.
Today on the podcast we are joined by Dr. Chris Petkov and Dr. Ben Wilson. Chris is a Professor of Comparative Neuropsychology and Newcastle University Medical School. Ben is a comparative neurosciencist studying how the brain evolved to support language. Previously he worked at Newcastle University, and is about to move to Emory University. We discuss how far back they can trace the origin of language, how they do it, and why language is so special to us humans after all.
