In this spectacular series, Professor Cox offers an original new perspective on human life: the story of a group of apes that evolved to leave their home planet and step out into the universe. 　　Humans are curious creatures. Of all the species on Earth, we alone ask questions. This series tackles the greatest questions we've ever asked. Where are we in the universe? Why are we here? How did the human brain arise and why did we become consciousness? Will our search for alien life be successful or are we all alone? And what is our future?
