AQA Science Exam Question and Answer

Question:

Discuss the domestication of dogs and their unique relationship with humans. Explain the evolutionary history of dogs from their wolf ancestors and the significant contributions of domestication to the diversity of dog breeds. Provide examples of the various roles dogs play in society, including their use in service, therapy, and as companions.

Answer:

  • The domestication of dogs is a remarkable example of the close bond between humans and animals. Through selective breeding and taming over thousands of years, dogs have become our loyal companions. Dogs descended from wolves, and their domestication began around 15,000 to 40,000 years ago. This process involved wolves exhibiting less aggressive behaviours, gradually adapting to human environments, and forming beneficial relationships with early human communities.
  • The domestication of dogs has led to an incredible diversity of breeds, each selectively bred for specific traits and purposes, such as hunting, herding, guarding, and companionship. Today, dogs hold various roles in society, serving as therapy animals for emotional support, guide dogs for individuals with disabilities, search-and-rescue dogs in emergencies, and even assisting law enforcement agencies.
  • Their loyalty, intelligence, and adaptability have made dogs valued members of our families and communities, and their contributions to society continue to make a significant impact in various areas of human life.
