Episode notes

Dolphins use sponges as protection when they are foraging on the sea floor. No males have ever been observed sponging like this, which is difficult to explain. All of the females are doing it and the males have yet to catch on. It's a wonderful example that demonstrates so many things about the cognitive abilities of different animals. But I think more than anything, it tells us something terribly important - we don't really know.

Most people in the modern world — and the vast majority of Mindscape listeners, I would imagine — agree that humans are part of the animal kingdom, and that all living animals evolved from a common ancestor. Nevertheless, there are ways in which we are unique; humans are the only animals that stress out over Game of Thrones (as far as I know). I talk with geneticist and science writer Adam Rutherford about what makes us human, and how we got that way, both biologically and culturally. One big takeaway lesson is that it’s harder to find firm distinctions than you might think; animals use language and tools and fire, and have way more inventive sex lives than we do. Adam Rutherford received his Ph.D. in genetics from University College London. He has written numerous books on genetics, evolution, synthetic biology, human history, and the origin of life. His most recent book is Humanimal: How Homo Sapiens Became Nature’s Most Paradoxical Creature — A New Evolutionary History. (Published in the UK with the more manageable title The Book of Humans: The Story of How We Became Us.) He frequently appears on and hosts science programs for the BBC on both radio and television, including Inside Science for BBC Radio 4.
