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 London between 1886 and 1890. Controversially, Romanes deviates from Darwin's assertion of the significance of geographical isolation, contending that physiological differences among the same species were central to evolutionary change. First published in 1892, Volume 1 focuses on the Darwinian theory itself. This second edition appeared in 1893.

Controversially, Romanes deviates from Darwin's assertion of the significance of geographical isolation, contending that physiological differences among the same species were central to evolutionary change. Published posthumously in 1897, Volume 3 considers the 'post-Darwinian question' of isolation, incorporating Romanes' own theories on physiological selection.

George John Romanes (1848-94) was an influential evolutionary biologist whose work focused on the evolution of mental faculties. Although criticised for his anecdotal method, he is credited as being one of the pioneers of comparative psychology for his work on animal intelligence, and he also contributed to the development of the theory of natural selection. Romanes and Charles Darwin (1809-82) were close friends, and Darwin gave Romanes his notes on psychology for use in his studies. First published in 1896, this biography was written by his wife Ethel (1856-1927), also an author on religious topics. This reissue is of the second printing (also 1896): including correspondence between Darwin and Romanes, it is a rich source of information on both men and the development of their work. This book is also fascinating for its account of Romanes' mental conflict between his Christian faith and belief in evolution.

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 Incorporating some of Darwin's unpublished notes, this book explores the question of whether human intelligence evolved.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 primates, the origin of self-consciousness and the possible reasons behind the apparent mental stasis of what Romanes terms 'savage man'. Following the argument that one of the main factors to be considered is language, the second half focuses on philology. Romanes' earlier work, Mental Evolution in Animals (1883), is also reissued in this series.

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 evidence over empirical research has been criticised, but this book stands as an influential work in the history of evolutionary biology; it was followed in 1888 by his Mental Evolution in Man (also reissued in this series), which discussed some of the most important issues of nineteenth-century evolutionary psychology.
