How the human voice became nature's most versatile instrument
Explore the biological evolution of sound in this lecture by Sophie Scott. Discover how everything from hissing cockroaches to opera singers uses frequency and resonance to communicate across the natural world.
In this lecture, Sophie Scott examines the diverse ways animals have adapted their bodies to produce audible messages, ranging from the chirps of crickets to the groans of deer. The presentation investigates the physics of sound, demonstrating how certain frequencies can even shatter glass.
The session explores the unique biological functions that allow humans to produce complex sounds, such as beatboxing and operatic arias. Scott also highlights the limitations of human hearing, noting that we are unable to perceive a fraction of the messages being sent by other species through different frequencies.
