The new genetic technology has advanced at breakneck speed. When the first genetically modified children, the twins Lulu and Nana, were born in China in 2018, it became clear that humanity was facing possibilities that we had, previously, only been able to imagine. With the pair of genetic scissors known as CRISPR, we could potentially choose the traits of our children and avoid ageing and disease. But with that ability comes a new set of risks, forcing us to face hard ethical and societal questions. How are we supposed to handle these new tools that could end up changing what is to be human?

Torill Kornfeldt has travelled all over the world to meet the people who are driving the research forward. She has visited fertility clinics in South Korea, oncologists in China who are experimenting on sick patients, and biohackers in the US who want to make the new technology available to everyone. In The Unnatural Selection of Our Species, she examines recent developments in gene editing and what might still be waiting around the corner.
