Measurements of bird flocking have been made [3] using high-speed cameras, and a computer analysis has been made to test the simple rules of flocking mentioned below. It is found that they generally hold true in the case of bird flocking, but the long range attraction rule (cohesion) applies to the nearest 5–10 neighbors of the flocking bird and is independent of the distance of these ...

In this video, we see the development of Possum the spotted pig into a sheep herder. It started out as a lark—the farmer noticed Possum chasing after the pigs in the field, and encouraging them ...
These genes affect embryogenesis and can confer tameness, smaller jaws, floppy ears, and diminished craniofacial development, which distinguish domesticated dogs from wolves and are considered to reflect domestication syndrome. The study concluded that during early dog domestication, the initial selection was for behavior.
