or is that ability something they are more biologically prepared for that has evolved over the course of domestication?" All of the 375 puppies were Labrador retrievers, golden retrievers or a lab-golden mix and were still living with their mother and litter mates. None had left to live with volunteer trainers, where extensive one-on-one human interaction would begin. An 8-week-old puppy follows a human gesture toward a treat under a cup. Puppies were "highly skillful" at following the person's cues of pointing and looking at just one of the cups where the treat was hidden, Bray said, and there was "no evidence that their performance required learning to do so." "Most of the puppies chose the right cup 70% of the time," she said. "They're not perfect, but it's definitely better than chance. There's something that they're picking up on, even at 8 weeks old." In fact, many of the puppies were able to follow a person's gesture or glance toward a hidden treat from the very first trial, with no training. More than 40% of the variation in a puppy's ability to follow a human's finger point or gaze could be explained by the genes they've inherited, Bray said. Make your rescue or foster pet a 'forever' friend "It is an equation that we can calculate because we know the performance on the behavior, and we know how related all the puppies are to each other, because we have their pedigrees," she said. "This is the first direct evidence to show there is a genetic basis." Baby talk a must Why did the
