On 24th November 1859, Charles Darwin's On the Origin of Species was first published. Describing the now well known theory that humans evolved through a process called natural selection, it became an instant classic and cemented Darwin as one of the greatest biologists of all time. However, he couldn't have done it without the support, encouragement and advice from those who believed in him. None more so than Joseph Hooker, his friend, confidant and fellow collector, who supported and helped Darwin when he didn't dare ask anyone else. Publishing in partnership with Royal Botanic Gardens, Kew, this book will show children how teamwork, curiosity, openness and trust can be the greatest tools a scientist will ever need.
