Charles Darwin

"He who admits that the structure and habits of all animals have been gradually evolved, will look at the whole subject of Expression in a new and interesting light." - Charles Darwin, The Expression of the Emotions in Man and Animals (1872)The Expression of the Emotions in Man and Animals (1872) includes original photographic as well as other illustrations by noted scientists Sir Charles Bell and French neurologist Duchenne, among others. This volume is the third in Darwin's explanation of his evolutionary theory, preceded by The Origin of Species (1859) and The Descent of Man (1871), and delves into the biology of emotions and whether those characteristics are exclusive to western civilization. Darwin links animal behavior to human emotions and provides the foundation for the work of noted psychologists such as Freud. This landmark work is a must-read for lovers of biology, Darwin, and psychology.

"...I was led to keep in my study during many months worms in pots filled with earth, I became interested in them, and wished to learn how far they acted consciously..." - Charles Darwin, The Formation of Vegetable Mould Through the Action of Worms (1881)The Formation of Vegetable Mould Through the Action of Worms, with Observations on their Habits (1881) includes original illustrations and highlights the extensive research and study of Darwin's landmark discoveries on soil formation, later termed soil bioturbation, as well as his fascination with earthworm behavior. In his last scientific book, published shortly before his death, Darwin documents with zest the earthworm's sexual passions and social interactions, as well as their significant contributions to the earth's ecosystem.This in-depth research is a must-read for lovers of ecology and biology.

"It has often and confidently been asserted, that man's origin can never be known: but ignorance more frequently begets confidence than does knowledge: it is those who know little, and not those who know much, who so positively assert that this or that problem will never be solved by science." -Charles Darwin, The Descent of Man, (1871)The Descent of Man, and Selection in Relation to Sex (1894 edition) with original illustrations by T.W. Wood reveals Charles Darwin's theories of human evolution with particular focus on the argument that sexual competition is the means for natural selection rather than an animal's physical and biological environment. Originally published in 1871, the book was an instant success. It remains a foundation for present-day research as an in-depth exploration noting the differences between the sexes. This book is a must-read for those interested in biology and Darwin's theories of evolution.

"...All the foregoing rules and aids and difficulties in classification are explained, if I do not greatly deceive myself, on the view that the natural system is founded on descent with modification; that the characters which naturalists consider as showing true affinity between any two or more species, are those which have been inherited from a common parent, and, in so far, all true classification is genealogical; that community of descent is the hidden bond which naturalists have been unconsciously seeking, and not some unknown plan of creation, or the enunciation of general propositions, and the mere putting together and separating objects more or less alike. But I must explain my meaning more fully..."
