Killer whales are an icon of the world's oceans. However, genetic studies show that they haven't always been doing so well- especially during the last Ice Age. What's the story? And what relevance does the millennia-old plight of the orca have today? On the podcast today, we're going to use a genetic study from 2014 to explore just that.
