In the 1959 Belyaev & his team spent many years breeding the silver fox & selecting only those individuals that showed the least fear of humans.
Eventually,Belyaev's team selected only those that showed the most positive response to humans . He ended up with a population of foxes whose behavior and appearance was significantly changed.
After about ten generations of controlled breeding. these foxes no longer showed any fear of humans. They often wagged their tails and licked their human caretakers to show affection.
Imagine what would happen if there is a nation which has been going through this for a couple centuries, & what more can possibly happen in the next couple decades? †
