Book excerpt: This early work by Alfred Russel Wallace was originally published in 1858 and we are now republishing it with a brand new introductory biography. 'On the Tendency of Varieties to Depart Indefinitely From the Original Type' is a short article on variation and evolutionary theory. Alfred Russel Wallace was born on 8th January 1823 in the village of Llanbadoc, in Monmouthshire, Wales. Wallace was inspired by the travelling naturalists of the day and decided to begin his exploration career collecting specimens in the Amazon rainforest. He explored the Rio Negra for four years, making notes on the peoples and languages he encountered as well as the geography, flora, and fauna. While travelling, Wallace refined his thoughts about evolution and in 1858 he outlined his theory of natural selection in an article he sent to Charles Darwin. Wallace made a huge contribution to the natural sciences and he will continue to be remembered as one of the key figures in the development of evolutionary theory.

This book was released on 2020-09-28 with total page 125 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present Depression of Trade is remarkable, not so much for its intensity or for its extent—in both of which respects it has been equalled or surpassed on previous occasions, but for its persistence during the long period of eleven years. The late Professor Fawcett, in his Free Trade and Protection (p. 151), says: “The industrial depression is generally thought to have commenced in the closing months of 1874;” and during every succeeding year it has continued to be felt with more or less severity, and its remarkable persistence has been commented on by politicians and public writers. Usually a period of depression is quickly followed by one of comparative prosperity. Such a reaction has been again and again predicted in this case; but up to the present time there are no satisfactory indications that the evil days are passing away. It is evident, therefore, that we are suffering in an altogether exceptional manner, that the disease of the social organism is due to causes or combinations of causes which have not been in action on former occasions, and that the remedial agencies which have been effective on former occasions of depression have now failed us. We thus find ourselves confronted with a problem of vital importance to our well-being as a nation. We are called upon to explain why it is that, notwithstanding the exceptional advantages we possess, in an ever-increasing command over the more recondite powers of nature, an ever-increasing use of labour-saving machinery, a body of labourers whose industry and skill are proverbial, and far more complete and perfect communication with the whole world than was possessed by any previous generation—notwithstanding all these favourable conditions, which would seem to render prosperity certain, we yet find trade crippled and labour paralysed, goods of all kinds selling at unremunerative prices, yet the masses too poor to buy, and universal complaints of diminished profits and restricted markets. So long as these questions are not fully and completely answered, so long as a remedy is not found for the widespread and persistent evil which afflicts the mass of our people, our whole system of social economy, even our civilisation itself, must be accounted to be failures. It will undoubtedly be admitted that a system of society under which willing hands cannot find profitable work, and countless shops and warehouses overflowing with every necessary, comfort, and luxury, mock the longing eyes of insufficiently-clad and half-starved millions, is neither a sound nor a safe one. We may therefore expect to find that the problem of trade-depression is fundamentally the same as that of the persistence of widespread poverty and pauperism notwithstanding our rapid and continuous growth in wealth; and if this be so, its solution will assuredly furnish us with some important principles to direct the course of future legislation. The main points of a sound political programme may be one of the important results of a successful investigation into the causes which have brought about the present depression of trade.

Book Synopsis In Darwin's Shadow by : Michael Shermer
Download or read book In Darwin's Shadow written by Michael Shermer and published by Oxford University Press. This book was released on 2002-08-15 with total page 443 pages. Available in PDF, EPUB and Kindle. Book excerpt: Virtually unknown today, Alfred Russel Wallace was the co-discoverer of natural selection with Charles Darwin and an eminent scientist who stood out among his Victorian peers as a man of formidable mind and equally outsized personality. Now Michael Shermer rescues Wallace from the shadow of Darwin in this landmark biography. Here we see Wallace as perhaps the greatest naturalist of his age--spending years in remote jungles, collecting astounding quantities of specimens, writing thoughtfully and with bemused detachment at his reception in places where no white man had ever gone. Here, too, is his supple and forceful intelligence at work, grappling with such arcane problems as the bright coloration of caterpillars, or shaping his 1858 paper on natural selection that prompted Darwin to publish (with Wallace) the first paper outlining the theory of evolution. Shermer also shows that Wallace's self-trained intellect, while powerful, also embraced surprisingly naive ideas, such as his deep interest in the study of spiritual manifestations and seances. Shermer shows that the same iconoclastic outlook that led him to overturn scientific orthodoxy as he worked in relative isolation also led him to embrace irrational beliefs, and thus tarnish his reputation. As author of Why People Believe Weird Things and founding publisher of Skeptic magazine, Shermer is an authority on why people embrace the irrational. Now he turns his keen judgment and incisive analysis to Wallace's life and his contradictory beliefs, restoring a leading figure in the rise of modern science to his rightful place.

Book Synopsis Charles Darwin In Cambridge: The Most Joyful Years by : John Van Wyhe
Download or read book Charles Darwin In Cambridge: The Most Joyful Years written by John Van Wyhe and published by World Scientific. This book was released on 2014-05-27 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: Charles Darwin's years as a student at the University of Cambridge were some of the most important and formative of his life. Thereafter he always felt a particular affection for Cambridge. For a time he even considered a Cambridge professorship as a career and sent three of his sons there to be educated. Unfortunately the remaining traces of what Darwin actually did and experienced in Cambridge have long remained undiscovered. Consequently his day-to-day life there has remained unknown and misunderstood. This book is based on new research, including newly discovered manuscripts and Darwin publications, and gathers together recollections of those who knew Darwin as a student. This book therefore reveals Darwin's time in Cambridge in unprecedented detail.

Book Synopsis Why Evolution is True by : Jerry A. Coyne
Download or read book Why Evolution is True written by Jerry A. Coyne and published by OUP Oxford. This book was released on 2010-01-14 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: For all the discussion in the media about creationism and 'Intelligent Design', virtually nothing has been said about the evidence in question - the evidence for evolution by natural selection. Yet, as this succinct and important book shows, that evidence is vast, varied, and magnificent, and drawn from many disparate fields of science. The very latest research is uncovering a stream of evidence revealing evolution in action - from the actual observation of a species splitting into two, to new fossil discoveries, to the deciphering of the evidence stored in our genome. Why Evolution is True weaves together the many threads of modern work in genetics, palaeontology, geology, molecular biology, anatomy, and development to demonstrate the 'indelible stamp' of the processes first proposed by Darwin. It is a crisp, lucid, and accessible statement that will leave no one with an open mind in any doubt about the truth of evolution.
