My guest this episode is Dr. Erich Jarvis, PhD—Professor and the 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 stutter/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, change our brains. For the full show notes, visit hubermanlab.com.Thank you to our sponsorsAG1 (Athletic Greens): https://athleticgreens.com/hubermanLMNT: https://drinklmnt.com/hubermanSupplements from Momentoushttps://www.livemomentous.com/hubermanTimestamps(00:00:00) Dr. Erich Jarvis & Vocal Communication(00:03:58) Sponsors: AG1, LMNT(00:08:01) Speech vs. Language, Is There a Difference?  (00:10:55) Animal Communication, Hand Gestures & Language (00:15:25) Vocalization & Innate Language, Evolution of Modern Language    (00:21:10) Humans & Songbirds, Critical Periods, Genetics, Speech Disorders (00:27:11) Innate Predisposition to Learn Language, Cultural Hybridization(00:31:34) Genes for Speech & Language(00:35:49) Learning New or Multiple Languages, Critical Periods, Phonemes (00:40:47) Sponsor: AG1(00:42:52) Semantic vs. Effective Communication, Emotion, Singing(00:47:32) Singing, Link Between Dancing & Vocal Learning (00:52:55) Motor Theory of Vocal Learning, Dance (00:55:03) Music & Dance, Emotional Bonding, Genetic Predispositions(01:04:11) Facial Expressions & Language, Innate Expressions(01:09:35) Reading & Writing (01:15:13) Writing by Hand vs. Typing, Thoughts & Writing(01:20:58) Stutter, Neurogenetics, Overcome Stutter, Conversations(01:26:58) Modern Language Evolution: Texting, Social Media & the Future(01:36:26) Movement: The Link to Cognitive Growth (01:40:21) Comparative Genomics, Earth Biogenome Project, Genome Ark, Conservation(01:48:24) Evolution of Skin & Fur Color(01:51:22) Dr. Erich Jarvis, Zero-Cost Support, YouTube Feedback, Spotify & Apple Reviews, Momentous Supplements, AG1 (Athletic Greens), Instagram, Twitter Neural Network Newsletter, Huberman Lab ClipsTitle Card Photo Credit: Mike BlabacDisclaimer

Jon Hamilton, an NPR science correspondent, hosts a captivating discussion with neuroscientist Erich Jarvis, chair of the Vertebrate Genomes Project. They explore the ambitious goal of sequencing 70,000 animal genomes to boost conservation efforts and understand evolution. The fascinating role of the platypus shines as a key player in unraveling mammalian traits. They also delve into the links between vocal learning and cognition in animals, pondering the ethical implications of genetic engineering related to vocalization.

In this engaging discussion, neuroscientist Erich Jarvis from Rockefeller University delves into the fascinating links between birdsong and human language. He reveals how both are rooted in similar brain structures and explores why some species vocalize while others do not. The conversation highlights vocal learning's rarity in nature and its implications for understanding communication across species, including fascinating insights into how birds develop their unique songs. Jarvis also touches on the evolutionary continuum of language, bridging gaps between various forms of communication.
