The world of hybrids can be both strange and perilous. In this episode, we explore two unique creatures born from human actions: the pizzly bear, a hybrid resulting from the mating of polar bears and grizzlies, a phenomenon exacerbated by climate change; and the notorious killer bee, created through the introduction of African bee species to South America. Both hybrids illustrate the unexpected consequences of human intervention in nature.
