Darwiniana is a collection of critical essays on Charles Darwin's theory of evolution that were originally published in scientific journals by his friend and correspondent Asa Gray, Professor of Botany at Harvard. Gray was one of Darwin's strongest supporters in the American scientific community he was also a Presbyterian and discussed questions of natural theology, design and teleology, including an earlier version of Chapter 3 of this book, with Darwin by letter over several years. Darwiniana 1876 was intended to provide a balanced assessment of Darwin's theory of evolution and to familiarise readers with the different aspects of Darwinism and its implications. The opening essays of the volume focus on the scientific and philosophical features of the theory, others analyse the reactions of Darwin's contemporaries and, most famously, argue for a reconciliation of religion and science in the light of Darwin's theory.
