How do crawdads clone themselves?

Author: Dustin Driver February 20, 2018 Duration: 6:57
In science fiction they call it gray goo - nanobots that replicate without limits until eventually everything on the planet is a featureless gray goo. It’s the first thing that came to mind when I read a recent article in the NY Times about a new species of crayfish that clones itself and is taking over Europe. The species emerged just 25 years ago as a mutation. Normally, animals have two chromosomes, one from each parent. This female crayfish ended up with three, meaning that she could produce her own fertilized eggs without mating. And every egg is a perfect clone of the original crayfish. Oh, and crayfish lay hundreds of eggs at a time. More from the German Cancer Research Institute: https://www.dkfz.de/en/presse/pressemitteilungen/2018/dkfz-pm-18-07-A-clonal-crayfish-from-nature-as-a-model-for-tumors.php

Dustin Driver hosts This is a Science Show, a space where curiosity meets conversation. It’s built on the idea that genuine discovery begins with admitting what we don’t understand. Each episode brings together leading researchers, thinkers, and storytellers to explore questions that sit at the intersection of hard science and human experience. You’ll hear discussions that range from the practical challenges of climate adaptation to the speculative futures of interstellar settlement and the long-term evolution of our species. This isn't just a lecture series; it’s a collaborative investigation into how scientific inquiry shapes our culture, our stories, and our society. The dialogue is grounded yet imaginative, always returning to that foundational moment of wonder. Tune in for a thoughtful and accessible journey through complex ideas, where every conversation is an invitation to think more deeply about our world and what lies beyond. This podcast thrives in the territory between known facts and the vast unknown, making the profound both engaging and relatable for anyone who’s ever looked up at the night sky and wondered.
