From The Life and Letters of Charles DarwinEdited by his Son Francis Darwin:My father's autobiographical recollections, given in this book, were written for his children,—and written without any thought that they would ever be published. To many this may seem an impossibility; but those who knew my father will understand how it was not only possible, but natural. The autobiography bears the heading, 'Recollections of the Development of my Mind and Character,' and end with the following note:—"Aug. 3, 1876. This sketch of my life was begun about May 28th at Hopedene (Mr. Hensleigh Wedgwood's house in Surrey.), and since then I have written for nearly an hour on most afternoons." It will easily be understood that, in a narrative of a personal and intimate kind written for his wife and children, passages should occur which must here be omitted; and I have not thought it necessary to indicate where such omissions are made. It has been found necessary to make a few corrections of obvious verbal slips, but the number of such alterations has been kept down to the minimum.—Francis Darwin

On the Origin of species. E-book. Formato EPUB Charles Darwin - Balungi Francis, 2020 -
This is the first edition of Charles Darwin's On the Origin of Species, published on November 24, 1859 in London by John Murray. It is a seminal work in scientific literature and a landmark work in evolutionary biology. It introduced the theory that populations evolve over the course of generations through a process of natural selection. It presented a body of evidence that the diversity of life arose by common descent through a branching pattern of evolution.The starting chapters introduce the theory of natural selection, explaining why certain species thrive, while others decrease in number, how the members of nature are in competition with each other and why organisms tend to vary and change with time. Much of this work is based on experiments and observations seen within domestic animals and plants.The later chapters defend the theory of natural selection against apparent inconsistencies, why geological records are incomplete, why we find species so widespread and how sterility can be inherited when the organisation is unable to reproduce and more.The book is approachable for any audience.
