Discoveries that changed the world

As it is impossible to rank them in order of importance, they are listed chronologically from as far back as 35,000 BC to the discovery of Oetzi, the Ice Man in 1991. Each article goes into detail about who the discoverers were, how the discoveries came about and their significance. For example, in 1543, while on his deathbead, Polish astronomer Nicholas Copernicus published his theory that the Sun is a motionless body at the centre of the solar system.
