In the last episode of Professor Brian Cox’s epic journey across the universe, he travels from the fossils of the Burgess Shale to the sands of the oldest desert in the world to show how light holds the key to our understanding of the whole universe, including our own deepest origins.
With some of the world’s most fascinating fossils in hand, Brian considers how but for an apparently obscure moment in the evolutionary history of life, all the secrets of light may have remained hidden. Because, although the universe is bathed in light that carries extraordinary amounts of information about where we come from, it would have remained invisible without a crucial evolutionary development.
Brian holds in his hand a fossil of one of the very first creatures to have an eye. Only because of that evolutionary development can we now observe, capture and contemplate the incredible wonders of the universe that we inhabit.
