On the Tendency of Species to form Varieties; and on the Perpetuation of Varieties and Species by Natural Means of Selection by Alfred Russel Wallace Pdf
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 Species to form Varieties' is a landmark article on Wallace's ideas of natural selection in relation to 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.
On the Tendency of Species to Form Varieties by Alfred Russel Wallace,Charles Robert Darwin Pdf
"On the Tendency of Species to form Varieties; and on the Perpetuation of Varieties and Species by Natural Means of Selection" is the name of a journal article that includes two scientific papers that were jointly presented to the Linnean Society of London on July 1st, 1858. The piece also includes an introduction by Joseph Dalton Hooker and Charles Lyell, as well as an abstract of a letter that Darwin wrote to Asa Gray. The Darwin-Wallace hypothesis of evolution through natural selection was initially introduced in the paper, which first appeared in print on August 20, 1858. Darwin was inspired by the papers' presentations to create an abbreviated "abstract" of his "huge book" on Natural Selection. On the Origin of Species, a version of this was released in November 1859.

Charles Darwin: On the Origin of Species & On the Tendency of Species to Form Varieties by Charles Darwin Pdf
This work of scientific literature is considered to be the foundation of evolutionary biology. For the sixth edition of 1872, the title was changed to The Origin of Species. Darwin's book introduced the scientific 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. Darwin included evidence that he had gathered on the Beagle expedition in the 1830s and his subsequent findings from research, correspondence, and experimentation. The book was written for non-specialist readers and attracted widespread interest upon its publication. As Darwin was an eminent scientist, his findings were taken seriously and the evidence he presented generated scientific, philosophical, and religious discussion. Charles Dickens (1812 – 1870) was an English writer and social critic. He created some of the world's best-known fictional characters and is regarded by many as the greatest novelist of the Victorian era.

This work of scientific literature is considered to be the foundation of evolutionary biology. Its full title was On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life. For the sixth edition of 1872, the title was changed to The Origin of Species. Darwin's book introduced the scientific 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. Darwin included evidence that he had gathered on the Beagle expedition in the 1830s and his subsequent findings from research, correspondence, and experimentation. Various evolutionary ideas had already been proposed to explain new findings in biology. There was growing support for such ideas among dissident anatomists and the general public, but during the first half of the 19th century the English scientific establishment was closely tied to the Church of England, while science was part of natural theology. Ideas about the transmutation of species were controversial as they conflicted with the beliefs that species were unchanging parts of a designed hierarchy and that humans were unique, unrelated to other animals. The political and theological implications were intensely debated, but transmutation was not accepted by the scientific mainstream. The book was written for non-specialist readers and attracted widespread interest upon its publication. As Darwin was an eminent scientist, his findings were taken seriously and the evidence he presented generated scientific, philosophical, and religious discussion. The debate over the book contributed to the campaign by T.H. Huxley and his fellow members of the X Club to secularise science by promoting scientific naturalism. Within two decades there was widespread scientific agreement that evolution, with a branching pattern of common descent, had occurred, but scientists were slow to give natural selection the significance that Darwin thought appropriate. During the "eclipse of Darwinism" from the 1880s to the 1930s, various other mechanisms of evolution were given more credit. With the development of the modern evolutionary synthesis in the 1930s and 1940s, Darwin's concept of evolutionary adaptation through natural selection became central to modern evolutionary theory, now the unifying concept of the life sciences.

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.
