The Quest to Decode Whale-speak

from Bioneers: Revolution From the Heart of Nature · host Bioneers

When members of Project CETI (the Cetacean Translation Initiative) witnessed the birth of a sperm whale, they observed a breathtaking scene of cooperation and communication that few humans on earth have ever seen. The extraordinary experience was both a scientific milestone as well as one more strand in the web of sperm whale culture that this innovative project is studying. The Project CETI team leverages world-leading technology and science in a quest to understand nonhuman animal communication. At the same time, the scientists leading the project are keeping an ethical throughline, placing the health and well being of whales at the center of the effort. As we get tantalizingly closer to truly communicating with other species, the question becomes not only whether we can, but whether we should - and what the implications are if we do.  This is an episode of Nature’s Genius, a Bioneers podcast series exploring how the sentient symphony of life holds the solutions we need to balance human civilization with living systems. Visit the series page to learn more. Featuring David Gruber is the Founder & President of Project CETI (Cetacean Translation Initiative), a nonprofit, interdisciplinary scientific and conservation initiative on a mission to listen to and translate the communication of sperm whales. He is a Distinguished Professor of Biology and Environmental Sciences at the City University of New York, Baruch College & The CUNY Graduate Center.
