It continues to be both popular and highly regarded. He wrote prolifically on both scientific and social issues his account of his adventures and observations during his explorations in Southeast Asia, The Malay Archipelago, was first published in 1869. He was one of the first prominent scientists to raise concerns over the environmental impact of human activity. His advocacy of spiritualism and his belief in a non-material origin for the higher mental faculties of humans strained his relationship with other scientists. Alfred Russel Wallace (1823-1913) was the third son of a man 'of independent means' who lost his fortune, and Alfred's childhood and education were marked by financial difficulties. Īside from scientific work, he was a social activist, critical of what he considered to be an unjust social and economic system in 19th-century Britain. ![]() ![]() His mother was English, while his father was of Scottish ancestry. a 7 He was the eighth of nine children born to Mary Anne Wallace ( ne Greenell) and Thomas Vere Wallace. He was one of the first scientists to write a serious exploration of whether there was life on Mars. Biography Early life Alfred Russel Wallace was born on 8 January 1823 in Llanbadoc, Monmouthshire. Wallace's 1904 book Man's Place in the Universe was the first serious attempt by a biologist to evaluate the likelihood of life on other planets. Who was Alfred Russel Wallace Alfred Russel Wallace was the, until recently, unknown Welsh Scientist who is credited with co-conceiving the theory of ‘Natural Selection’ in animals and plants back in 1858 in a joint paper with Charles Darwin. Wallace was one of the leading evolutionary thinkers of the 19th century, working on warning coloration in animals and reinforcement (sometimes known as the Wallace effect), a way that natural selection could contribute to speciation by encouraging the development of barriers against hybridisation. He was considered the 19th century's leading expert on the geographical distribution of animal species, and is sometimes called the "father of biogeography", or more specifically of zoogeography. Although now rarely mentioned as the discoverer (Darwin, who discovered the theory independently, is usually cited) Wallace enjoyed a high reputation in his lifetime and received many of science’s most prestigious awards. He then did fieldwork in the Malay Archipelago, where he identified the faunal divide now termed the Wallace Line, which separates the Indonesian archipelago into two distinct parts: a western portion in which the animals are largely of Asian origin, and an eastern portion where the fauna reflect Australasia. Alfred Russel Wallace discovered the concept of evolution by natural selection. Wallace did extensive fieldwork, starting in the Amazon River basin. Gold Medal of the Société de Géographie (1870).With such amiable weaknesses as anti-vaccination and spiritualism we are not concerned, but we greatly miss a more extended account of the work that really made Wallace's reputation. 47, besides some careless punctuation, there is a distinct error of fact. On the subject of geographical distribution the tone of the book is scarcely fair and on p. Hogben had given us in its place a few more particulars of the exploration of the Amazon and of the Malayan islands. Details of Wallace's early life are interesting in their bearing on his later development, but we could have spared the account of the arrangement of desks and fireplaces in the grammar school at Hertford if Mr. ![]() In view, however, of his necessary limits, it is to be regretted that the author has not observed a better proportion in the selection of facts to be recorded. He also developed the study of biogeography - how patterns of species are distributed across the world. He is most known for having come up with the revolutionary idea of evolution by natural selection entirely independently of Charles Darwin. ![]() Hogben's volume does not pretend to be more than a sketch. Alfred Russel Wallace (1823 1913) was a fearless Victorian naturalist and explorer. It is obvious that the life of such a man cannot be treated adequately in a small book of sixty-four pages, and Mr. Alfred Russel Wallace (1823-1913) was the third son of a man of independent means who lost his fortune, and Alfreds childhood and education were marked by financial difficulties. Y donde hizo algunos de los descubrimientos científicos más importantes de los últimos tiempos. THE name of Alfred Russel Wallace is rightly held in honour as that of one who with few advantages of birth or education made for himself a distinguished position as naturalist and traveller, and who, besides adding largely to the acquaintance of scientific men with certain regions previously little known, and making extensive collections of their fauna, achieved independently the discovery of natural selection, the most illuminating principle ever enunciated in the history of biological study. Es la tierra que Alfred Russel Wallace exploró durante ocho años, desde 1854 hasta 1862.
