TED-Ed: David Ian Howe: A brief history of dogs

Modern humans have spread across the globe, often accompanied by domestic dogs, which evolved from gray wolves, our ancient rivals. As wolves adapted to human presence, they became more docile, leading to domestication. Early dogs helped humans hunt and guard, eventually becoming the first domesticated animals. Over time, diverse dog breeds emerged, some with health issues due to selective breeding. The process of domestication favored juvenile traits, a phenomenon known as neoteny. This long co-evolution has created a strong bond between humans and dogs, marked by mutual understanding and shared emotions.
