Story
Kirby and Charlie explore the current theory that dogs did not descend from gray wolves, but that dogs and wolves have a common ancestor. They discuss the theory that 27,000 years ago dogs might have approached the garbage thrown out by humans at the edge of a settlement. If the dogs were aggressive, they were likely chased away but not if they were friendly. They further speculate the friendly dogs joined in hunts and were sometimes useful as emergency food. The theory goes that the common ancestor dog went extinct but dogs have changed quite a bit through evolution, breeding and artificial selection, a breed whose scientific classification is canis familiaris. Testing has proven that when a human looks into the eyes of a dog, it increases the dog's oxytocin level by over 100% and when the dog looks back at the human, it increases the human's to over 300%.
