Cooperation between humans and animals is not common, but does happen. Killer whales in Eden, New South Wales, had cooperatively hunted baleen whales with Indiginous peoples for millenia, and then for a short time with the commercial whalers of the late 19th and early 20th centuries. Eventually the baleen whales they hunted became scarce, and so did the Eden killer whales. Was their disspearance due to lack of prey, a breach in protocol (did the humans break the Law of the Tongue), or something else? Did they just die out, or spread their genes elsewhere? Genetics can help solve at least some of this mystery. This is the story of the Eden killer whale, Old Tom, and his pod. Join us as we discuss this unique relationship, and what possibly became of those killer whales.
