"Dr Adam Rutherford concludes his compelling journey through 350 years of science to discover the secrets of the cell and of life itself. The Spark Of Life begins with some of the earliest evidence of life on Earth: fossilised cells that are a staggering one billion years old. It is now believed that all life on Earth began with one primordial cell from which every living thing evolved. Today, however, knowledge of the cell has brought humankind to the brink of something truly profound. Scientists may be about to create living cells from scratch and, if they succeed, it will be the first life form on Earth that has not evolved from that original cell. It would be the Second Genesis."
