Human Vocalization: Its Evolution and its Use to Study Evolutionary Migrations
Friday, November 21, 2009
Lecture Hall 8, 4:00 PM
Human beings are among a handful of animal groups that have the capacity for vocal learning. Vocal imitation provides a basis for both the developmental acquisition and cultural evolution of languages and musical systems. I will present neuroimaging findings on the identification of a larynx-controlling area in human motor cortex, and discuss the evolutionary implications when looking at larynx representations in the non-human primate brain. Moving then to a cultural view of vocalization, I’ll make mention of work investigating the potential use vocal forms, mainly song styles, as markers for the analysis of human migrations, with a focus on the Austronesian expansion.
