Blood Lines

How do different animals go about the business of parenting? And what drives some species to stick around their offspring, while others walk away? It’s all about genetic heritage. In this episode, we trace the tactics, trials and tribulations of a vast array of different species in their fight to further their bloodline. From the capybara mom who chooses to lose one baby to save seven, to the elephants standing vigil over an unknown calf, this is a journey into what really makes animal parents behave as they do.
