Domestic dogs are all one species. Similarly, all humans are species homo sapiens with race differences resulting from separation over thousands of years by geographic barriers. Dog breeds and human races are directly analogous as sub-groups within the respective species. <BR/><BR/>Much can be learned from studying dogs; medical science does a great deal of this to avoid experimentation on humans. The brain is no exception, as dog and human brain structure and information flow processes are very similar to that in humans. Numerous dog brain studies to analyze human brain diseases/conditions are in the medical literature.<BR/><BR/>Any experienced domestic animal breeder will acknowledge the profound influence of genetics on intelligence and behavior. Traits such as trainability, aggression, prey drive, docility, bite inhibition are highly heritable and difficult to modify. Extensive evaluations of dog intelligence have developed breed rankings according to ease of training (number of repetitions needed to learn a command) and reliability (percent of time) of correct response to learned commands. Instinctive ability to to take correct action in complex situations is also recognized to vary with breed (there is a valid reason police K-9 units use German Shepherds instead of Pit Bulls). Among dog breeds, there is a huge Achievement_Gap. This is all easily Googled… <BR/><BR/>You can talk openly about dogs without being politically incorrect. You won’t get into trouble, lose your career or research grants, as you might if you reveal unpleasant truths about humans: e.g., James Watson, Jimmy the Greek, Al Campanis, Don Imus…<BR/><BR/>Humans are not exempt from the fundamental rules of biology.Anonymousnoreply@blogger.com
