Honed Instincts

Through hundreds of thousands of years of evolution, canines' senses and instincts have been honed to become fine-tuned instruments of survival. Dogs have been known to anticipate earthquakes, predict their owners' heart attacks, and detect imminent danger when the humans around them see, hear, and smell nothing, such as the bioterrorist threat when raccoons wander onto the porch.

My dogs, for example, employing the fine-tuned senses inherited from their prehistoric ancestors, know instantly, no matter how far away they are, when I am reheating pizza. They also make strong use of their atavistic ability to catch air-popped popcorn in midair when it escapes the gravity of the popcorn bowl.

Are they amazing, or what?
