The most distinctly different brains, however, might be found among dogs who will die and not pass along their genes if they fail at their specialized work. Most of the highly technical paper describes the methodology of the MRI analysis, done to distinguish what parts of the canine brain evolved first, and are therefore shared in more or less equal proportion among all dogs, versus what parts have taken on different proportions during the relatively brief time in which dogs have been selectively bred by humans.
