Research on animal behaviour has shown that if you serve two dogs (that know each other) an unfair treat, they know and show anxiety. So isn’t basic morality hardwired in some species? Wouldn’t we be one of these? As soon as we appreciate quantity, we acquire the rudiments of morality, in other words, what is fair and unfair (Letters, 14 September).
