The biologist Liz Bonnin explores why some of the most bizarre and surprising animals pair up with each other, and with us. She'll scour the globe in search of the most extraordinary and cute animal relationships to investigate why such odd couples sometimes pair up. Everything from dogs mothering baby tigers and polar bears befriending huskies; to buffalos bonding with grown men and lions behaving like our brothers. We're utterly captivated by animals that behave in ways that we think of as uniquely human. Millions of us watch clips of animals showing friendship, genuine affection and maybe even love towards totally different species that would never normally come together. But these are not just freak occurrences; there is real science to explain these bonds.
