Question: Why do we have names?

Sam Geen answered on 18 Jun 2013:

So we can tell people apart when we’re telling each other about people who aren’t there! Second names are sometimes related to what your ancestors did – people called Smith used to be blacksmith families, for example. Dolphins apparently also use names – they have sounds that they tell each other when they first meet, and then they use them later. Dogs, of course, can recognise their own names but they can’t talk to say them…
