The Short Answer

Domestic dogs (and cats) have been preferentially bred for being non-aggressive (amongst other things) for thousands of generations. As a result they are psychologically a weird; they act alot like immature wild dogs (and cats). Wild dogs don't bark, but wild dog pups do. (Again, same with meowing in cats) This is why adult domestic dogs love to play, while adult wild dogs rarely do. 'Fetch' games seem like a version of the kind of play wild pups might do, chasing 'prey'. Many domestic dogs were also bred for hunting, and the ability to fetch the duck you just shot (or conked with a rock) would be a behaviour that would be favoured. I don't know if such a behaviour could be 'hardwired', and dogs can't inherit a learned behaviour, but I'd think that dogs who had a natural tendency to 'retrieve' would be favoured, and bred more than the dogs that eat the duck, then run round in circles while your neighbours laugh at you. Like my dog… (won't fetch, thinks he's above it. Or maybe he's just too smart)
