➍ In the initial stages of the experiment, / no significant changes were observed / in the foxes. // However, / with the 6th generation came the appearance of an “elite fox,” / or in other words, / an obedient fox / that behaved more affectionately / and exhibited behaviors / such as tail wagging,  whining, and licking people / like a pet dog. // Furthermore, / when a 15th generation “elite fox” was living with humans, / researchers observed signs of a deep bonding / and affection between a human and the fox. // One day, /  much like a guard dog, / the fox barked at a security guard / that it thought / was an intruder and stopped barking on command, / suggesting that the fox had developed the loyalty of a dog. //
