The Language of Bees | Dr. James C. Nieh | Natan Podcast #4
Honeybees are the only animals besides us that tell each other where to find food. Dr. James Nieh has spent thirty years decoding how they do it, from the waggle dance to the "stop signal" he discovered when his first experiment fell apart, and he thinks their language evolved as encryption against enemy spies.
THE BOOK The Language of Bees: https://www.amazon.com/Language-Bees-James-C-Nieh/dp/0691204896 (https://www.amazon.com/Language-Bees-James-C-Nieh/dp/0691204896)
THE PLAYLIST Free videos of the waggle dance, stop signal, and colony warfare: https://www.youtube.com/watch?v=zEquVG35La0&list=PLeqMCDrvHGdNn10XWL4jmJ1O-42FJVL1H (https://www.youtube.com/watch?v=zEquVG35La0&list=PLeqMCDrvHGdNn10XWL4jmJ1O-42FJVL1H) 00:00 – Cold open: bees hear through hairs, and honey burial for kings 00:28 – What a world without bees actually looks like 01:38 – Quitting biology for medieval history, then coming back 02:58 – The waggle dance: direction from the sun, distance from duration 05:12 – Navigating a pitch-black nest (polarized light, ocelli, gravity hairs) 07:15 – Inside a bee's mind: UV vision, vibration, electric charge on flowers 10:16 – A day in the life of a bee researcher 11:48 – Cross-fostering two species: distance dialects and genetic pull-back 14:30 – Bees in religion, honey as medicine, honey burial 19:09 – The failed experiment that became the stop signal 26:01 – Spies, odor trails, and why the dance may be encrypted communication 29:58 – Why bees look the way they do: warning coloration and cheaters 31:54 – The superorganism: queens live years, workers live 40 days 34:58 – Who actually decides when a new queen is made (not the queen) 36:54 – Is there a hive mind?
