A Brief History of Dogs | National Geographic

Summary

The script explores the ancient relationship between humans and dogs, tracing their domestication from wolves around 20,000 to 40,000 years ago. It highlights how certain wolves less fearful of humans were favored for their tameness, leading to the development of dogs. The ancient Egyptians and Chinese played significant roles in selective breeding for specific purposes and appearances. By the 19th century, purebred dogs became status symbols, and crossbreeding led to the first dog shows. Today, with over 300 breeds, dogs are Earth's most diverse species, but selective breeding has also led to genetic disorders. Despite this, dogs have become integral to human life, serving as pets, therapy, search-and-rescue, and war dogs, while advancements in veterinary care and rescue organizations ensure their well-being.
