LOL what a load of unsourced unscientific bullcrap What about making this article more scientific so people can actually use it There is no technical info Come on it doesn t take an university degree to describe it It s merely selective breeding it is well documented and has been practiced for 1000 s of years with animals It shouldn t be hard to describe the science behind it as the mechanisms are exactly the same with humans There are no principal differences between breeding an intelligent search dog and an intelligent human the method is the same 93 161 107 169
