Dear reader, the video is a little lower. The dog is a domesticated descendant of wolves. Also called the domestic dog, it was selectively bred during the Late Pleistocene by h∪nter-gatherers. Dogs and the modern gray wolf share a common ancestor. Dogs were the first species to be domesticated over 14,000 years ago, before the development of agriculture, though genetic studies suggest the domestication process may have begun over 25,000 years ago. Due to their long association with humans, dogs have gained the ability to thrive on a starch-rich diet that would be inadequate for other canids.
Dogs have been br℮d for desired behaviors, sensory capabilities, and physical attributes. Dog breeds vary widely in shape, size, and color. They have the same number of bones (with the exception of the tail), powerful jaws that house around 42 teeth, and well-developed senses of smell, hearing, and sight. Compared to humans, dogs possess a superior sense of smell and hearing, but inferior visual acuity. Communication in dogs includes eye gaze, facial expression, vocalization, body posture (including movements of bodies and limbs), and chemical communication. The global dog population is estimated at 700 million to 1 billion.
