Do humans have more hair than dogs?
Humans have significantly less hair than dogs. While humans have an average of 100,000 hair follicles on their head, dogs can have up to 700 per square inch on their bodies. This is due to the fact that dogs have evolved to survive in colder climates and need more hair to insulate their bodies. Humans, on the other hand, have lost much of their body hair through evolution and rely on clothing to regulate their body temperature.
