Dogs: Our Oldest Friends

A tiny fragment of jawbone discovered in Gough's Cave in Somerset has transformed our understanding of when dogs became domesticated. DNA analysis confirmed that this bone belonged to one of the earliest known dogs, proving that humans and dogs lived closely together in Britain 15,000 years ago.
The discovery pushes back the timeline of dog domestication by approximately 5,000 years. Dr. William Marsh from the Natural History Museum made this breakthrough by accident while researching specimens that had been stored in museum drawers since the 1920s. Initially thought to be unremarkable, the jawbone turned out to be a crucial piece of evidence.
The first dogs descended from grey wolves that lingered around human settlements at the end of the Ice Age, scavenging for food scraps. Over many generations, these animals became tamer and evolved into working partners for hunting and guarding. Chemical analysis revealed that these ancient dogs ate the same diet as their human owners, suggesting an incredibly close bond.
Further genetic testing of similar specimens across Europe and Turkey confirmed that early dogs had already spread widely across the continent, traveling alongside their human companions. This remarkable relationship between humans and dogs has lasted for 15,000 years and continues today.
