George John Romanes (1848 94), considered by The Times to be 'the biological investigator upon whom in England the mantle of Mr. Darwin has most conspicuously descended', wrote this influential work on the evolution of the mental faculties of animals in 1883. The two scientists were close friends, and Darwin gave Romanes his notes on psychology to use in his studies. Much of the book is devoted to instinct, and contained in the appendix is a posthumous essay by Darwin on the subject, originally intended for a later edition of On the Origin of Species. Romanes' method of using anecdotal...

George John Romanes (1848 94) was considered by The Times to be 'the biological investigator upon whom in England the mantle of Mr. Darwin has most conspicuously descended'. Incorporating some of Darwin's unpublished notes, this book explores the question of whether human intelligence evolved. In a stance still often considered controversial at the time of its first printing in 1888, the first half establishes a link between humans and animals, and introduces some of the most important issues of nineteenth-century evolutionary psychology: the impact of relative brain sizes of humans and...

George John Romanes (1848 94), evolutionary biologist, was one of the most zealous supporters of Darwin's theory of evolution by natural selection in the nineteenth century. He met Darwin in 1874 and became a firm friend and follower, applying Darwinian theory to his work on animal intelligence and mental evolution. Romanes was elected to the Royal Society in 1879 at the age of 31, having produced his own influential research on the evolution of the nervous system. This three-volume study of Darwin's work and its implications was first developed as a series of lectures given in Edinburgh and...
