It was harder to work out that there was a question than to think of the answer. - Richard Dawkins

You see, if you say something positive like the whole of life – all living things – is descended from a single common ancestor which lived about 4,000 million years ago and that we are all cousins, well that is an exceedingly important and true thing to say and that is what I want to say. Somebody who is religious sees that as threatening and so I am represented as attacking religion, and I am forced into responding to their reaction. But you do not have to see my main purpose as attacking religion. Certainly I see the scientific view of the world as incompatible with religion, but that is not what is interesting about it. It is also incompatible with magic, but that also is not worth stressing. What is interesting about the scientific world view is that it is true, inspiring, remarkable and that it unites a whole lot of phenomena under a single heading. And that is what is so exciting for me.

Replicators are no longer peppered freely through the sea; they are packaged in huge colonies—individual bodies. And phenotypic consequences, instead of being evenly distributed throughout the world, have in many cases congealed into those same bodies. But the individual body, so familiar to us on our planet, did not have to exist. The only kind of entity that has to exist in order for life to arise, anywhere in the universe, is the immortal replicator.

That it will never come again Is what makes life so sweet.
