When the jogging/fitness craze first began it became clear that surprising numbers of people thought that survival of the fittest, in the Darwinian sense, had something to do with the need to exercise
It strikes me that the famous Watson/Crick model, especially in its modern multi-coloured ball & stick representation, encourages many people to think that you can design a baby in the same way that you can design a necklace, by picking & choosing from a tray of all available genes which look just like beads
And its surprising how many people react I hadnt thought of that if you point out that designer babies mean the end of the fun of making them in the old fashioned way.
