Evolutionary Adaptations for Human Companionship

Dogs have evolved specific traits through thousands of years of domestication that make them perfect human companions:

• Expressive eyebrows: Dogs developed movable eyebrows to create "puppy dog eyes," a trait not found in wolves, likely evolved because humans find it endearing.
• Eye contact: Unlike their wolf ancestors, dogs actively seek eye contact with humans as a form of bonding and communication.
• Genetic predisposition: Dogs have undergone genetic changes making them exceptionally friendly towards humans.
