The brain, like the rest of the body appears to structurally change in response to demands placed upon it. Calcium migrates in bones, muscles tone, and the brain adapts according to stress in our environment. In short, we dynamically evolve to meet the requirements of our environment.

This means the brain is as plastics as the rest of the body. Dogs CAN learn new tricks.

The next question now is, what part does epigenetics play in this evolution?
