My guest this episode is Dr. Erich Jarvis, PhD—Professor and Head of the Laboratory of Neurogenetics of Language at Rockefeller University and Investigator with the Howard Hughes Medical Institute (HHMI). Dr. Jarvis' research spans the molecular and genetic mechanisms of vocal communication, comparative genomics of speech and language across species and the relationship between speech, language and movement. We discuss the unique ability of humans (and certain animal species) to learn and communicate using complex language, including verbal speech production and the ability to interpret both written and spoken language. We also discuss the connections between language, singing and dance, and why song may have evolved before language. Dr. Jarvis also explains some of the underlying biological and genetic components of stuttering/speech disorders, non-verbal communication, why it's easiest to learn a language as a child and how individuals can learn multiple languages at any age. This episode ought to be of interest to everyone interested in the origins of human speech, language, music and culture and how newer technology, such as social media and texting, changes our brains.
