![]() ![]() He died in Broadstone, Dorset in 1913 at the age of 90. He also fathered the field of biogeography, becoming the leading expert on the geographical distribution of animal species. Wallace's research motivated Darwin to publish On the Origin of Species, co-crediting Wallace for the discovery of natural selection. During this time, he developed an insight on natural selection, and he shared his research with Charles Darwin, who had similar ideas, but had not yet published them due to fears of ostracization from Victorian society. In 1848, he and Henry Walter Bates travelled to Brazil to collect insects and other animal specimens for pvitae collections, and he travelled to the East Indies from 1854 to 1862. It continues to be both popular and highly regarded.Alfred Russel Wallace (8 January 1823-7 November 1913) was a British naturalist, explorer, geographer, anthropologist, and biologist who was famous for independently conceiving the theory of evolution through natural selection at the same time as Charles Darwin, with whom he was co-credited for On the Origin of Species.Īlfred Russel Wallace was born in Llanbadoc, Monmouthshire, Wales in 1823, and he taught drawing, mapmaking, and surveying at the Collegiate School in Leicester before deciding to take part in travels abroad as a naturalist. Bei seinem Aufenthalt im Malaiischen Archipel erkannte er. Sein offizielles botanisches Autorenkrzel lautet Wallace.

Materials on and by the English naturalist and social critic Alfred Russel Wallace (1823-1913), including bibliographies, lists, commentaries, a biography. 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. Alfred Russel Wallace (etwa 1895) Alfred Russel Wallace OM ( 8. But, there was also another who also worked on. ![]() He was one of the first prominent scientists to raise concerns over the environmental impact of human activity. When you think of natural selection, you may think of Charles Darwin. 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. 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. He was one of the first scientists to write a serious exploration of whether there was life on Mars. 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. 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. 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. Wallace did extensive fieldwork, starting in the Amazon River basin. Gold Medal of the Société de Géographie (1870).
