When life begins to form, the very first cell divides into two perfectly identical copies, which divide into two more copies that are identical too, and so on. Despite this, at a given time, one cell will become a brain cell, and another a blood cell. Though each of these cells has exactly the same genes, at one point during embryogenesis, they will specialise by using only the genes they need. It is one of the wonders of Nature.
