Explore the fascinating world of animal communication in this 58-minute Christmas Lecture from The Royal Institution, recorded on December 2, 1985. Discover how animals use diverse methods to communicate for reproduction and complex social interactions, often employing senses and signals beyond human perception. Learn about animals that utilize sounds and colors invisible to humans, coded messages requiring special instruments to decipher, and sophisticated scent-based communication systems. Examine the remarkable world of electric fish that use weak electrical signals underwater and detect them through specialized skin sensors, as well as species that employ "touch at a distance." Investigate how animals balance communication needs with survival, from venomous species that boldly advertise their danger to harmless creatures that engage in deceptive mimicry. Understand interspecies communication, including plant-animal interactions and the cooperative relationships between humans and domestic animals. Delve into the fundamental principles governing all forms of communication, from personal exchanges to the intricate methods employed across the animal kingdom, as part of a comprehensive exploration that connects microscopic nerve membranes to worldwide technological systems and extends into space.
