Ever since the discovery of DNA, we have fanstasised about creating new species of animals, or even 'improved' humans. But it is only in the last few years that a new gene editing technology, CRISPR, has made this a reality. Many claim it is already unstoppable, that we will always demand solutions to diseases if they are possible. Is CRISPR the key to improving health and defeating ageing? Will it lead to a new age of transhumans and unleash humanity's potential? Or is this a dangerous fantasy that could lead to the reckless use of a technology we need to limit in order to safeguard the human race?
Author of Superior Angela Saini, molecular biologist and Director of Editing Nature at Yale Natalie Kofler and founder of Humanity+ David Pearce explore the radical new possibilities of biotechnology.
