Tv-vært Puk Elgård

Danish TV host Puk Elgård spent a year writing a book about the deep evolutionary bond between humans and dogs, and the conversation reveals just how radical that bond actually is. The genetic difference between a wolf and a tiny lapdog like her own Hugo is only 0.04 percent — meaning they are 99.96 percent identical. Yet in a mere 10,000 years, a blink in evolutionary time, the wolf transformed into an animal whose brain has rewired itself to understand human language, read human emotions, and even trigger the same hormonal response in us as looking at a baby or a romantic partner.

The hunting alliance that changed everything

The story begins 45,000 years ago, when Homo sapiens wandered out of Africa into Ice Age Europe and encountered the grey wolf — "the king of the ice age," as Elgård describes it. At first, they were enemies. But both species hunted the same prey, including the woolly rhinoceros, a dangerous animal the humans could kill at a distance with spears while the wolves could surround and immobilize it. In this shared hunting ground, a mutual benefit emerged: humans began leaving meat for the wolves that helped them. Over generations, the wolves with the least aggressive, most curious temperaments received more food and reproduced more successfully. This self-selection process happened faster than Darwin himself thought possible.
