... To build a fruit fly, you need (among other things) a set of genes known as Hox genes. These are ‘master control’ genes that coordinate the activity of many other genes, so a head, abdomen, legs, antennae and all the other bits of a fly are built in the right place. You need essentially the same genes ...
