"A Origem das Esp cies" votado como livro mais influente da hist ria. " certamente verdadeiro que se v em raramente aparecer num indiv duo novos rg os que parecem ter sido criados com um fim especial; mesmo o que demonstra o velho axioma de hist ria natural de que se tem exagerado um pouco a significa o: Natura non facit saltum. A maior parte dos naturalistas experimentados admitem a verdade deste ad gio; ou, para empregar as express es de Mlne Edwards, a natureza pr diga em variedades, mas avara em inova es." "Como a selec o natural actua somente acumulando varia es ligeiras, sucessivas e favor veis, n o pode produzir modifica es consider veis ou s bitas; s pode agir a passos lentos e curtos. Esta teoria torna f cil de compreender o axioma: Natura non facit saltum, que cada nova conquista da ci ncia mostra logo todos os dias ser verdadeiro."

On the Origin of Species (or more completely, On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life), published on 24 November 1859, is a work of scientific literature by Charles Darwin which is considered to be the foundation of evolutionary biology. Darwin's book introduced the scientific theory that populations evolve over the course of generations through a process of natural selection.

The Expression of the Emotions in Man and Animals is a book by Charles Darwin, published in 1872, concerning genetically determined aspects of behaviour. It was published thirteen years after On the Origin of Species and, alongside his 1871 book The Descent of Man (of which it was originally intended to form a part), it is Darwin's main consideration of human origins. In this book, Darwin seeks to trace the origins of such human characteristics as the pursing of the lips in moments of concentration and the mental confusion which typically accompanies blushing. Before Darwin, mental life had often been considered in terms of associationist psychology. Darwin's biological approach links mental states to the neurological organization of movement; and he sought out the opinions of some leading British psychiatrists, notably James Crichton-Browne, in the preparation of the book which forms his main contribution to psychology. Amongst the innovations with this book are Darwin's circulation of a questionnaire in his preparatory research; simple psychology experiments on emotional recognition with his friends and family; and (borrowing from Duchenne de Boulogne, a physician at the Salp tri re) the use of photographs in his presentation of scientific information. The Expression of the Emotions is an important landmark in the history of book illustration.
