Alfred Russel Wallace Alfred Russel Wallace was born in a small village of Usk, which is located in Wales. Shortly after finishing school, Wallace's father passed away and he joined his brother surveying countries. Wallace continued to do work with the brother surveying countries for four years. Through this experience, he acquired his talent for observation and detailed recordings which helped immensely later on in his life. Alfred Wallace is best known for his theory of natural selection . From 1854 to 1862 he and his mentor Henry Walter Bates explored the Amazon River. It was during this expedition that he saw differences between the animals in Asia and the animals in Australia. From this observation he put a line between the Malay islands and Celebes which he called the Wallace�s Line. Out of this experience came his theory of natural selection. After he thought about this theory he wrote a manuscript called �On the Tendency of Varieties to Depart Indefinitely from the Original Type.� Instead of just sending his manuscript straight to the publishers, he first sent it to Charles Darwin . At this time Darwin saw so many similarities with his theory that he decided to publish his theory right away. To this day, Wallace�s greatest accomplishment was to get Charles Darwin to publish his own theory.

When we are pre­sent­ed with a com­plex prob­lem de­pend­ing on a great num­ber of im­per­fect­ly as­cer­tained da­ta, we may of­ten check the re­sults thus ob­tained by the com­par­ison of cas­es in which some of the more im­por­tant of these da­ta are iden­ti­cal, while oth­ers are at a max­imum or a min­imum. In the present case we can do this by a con­sid­er­ation of the Moon as com­pared with the Earth and with Mars. _Lan­gley's De­ter­mi­na­tion of the Moon's Tem­per­ature._ In the moon we see the con­di­tions that pre­vail in Mars both ex­ag­ger­at­ed and sim­pli­fied. Mars has a very scanty at­mo­sphere, the moon none at all, or if there is one it is so ex­ces­sive­ly scanty that the most re­fined ob­ser­va­tions have not de­tect­ed it. All the com­pli­ca­tions aris­ing from the pos­si­ble na­ture of the at­mo­sphere, and its com­plex ef­fects up­on re­flec­tion, ab­sorp­tion, and ra­di­ation are thus elim­inat­ed. The mean dis­tance of the moon from the sun be­ing iden­ti­cal with that of the earth, the to­tal amount of heat in­ter­cept­ed must al­so be iden­ti­cal; on­ly in this case the whole of it reach­es the sur­face in­stead of one-​fourth on­ly, ac­cord­ing to Mr. Low­ell's es­ti­mate for the earth.

He is best known for independently proposing a theory of evolution due to natural selection that prompted Charles Darwin to publish his own theory. Wallace did extensive fieldwork, first in the Amazon River basin and then in the Malay Archipelago , where he identified the Wallace Line that divides Indonesia into two distinct parts, one in which animals closely related to those of Australia are common, and one in which the species are largely of Asian origin. He was considered the 19th century's leading expert on the geographical distribution of animal species and is sometimes called the "father of biogeography Wallace was one of the leading evolutionary thinkers of the 19th century and made a number of other contributions to the development of evolutionary theory besides being co-discoverer of natural selection. These included the concept of

Wallace effect From Wikipedia, the free encyclopedia Jump to: navigation search The Wallace Effect is a hypothesis developed by British naturalist Alfred Russell Wallace which posits that natural selection can contribute to the reproductive isolation of incipient species by encouraging varieties to develop barriers to hybridization Contents Historical development Current status Notes References ... edit Historical development In Wallace's 1889 book Darwinism , he explained and defended the theory of natural selection, first widely presented in 1859 by Charles Darwin in On the origin of species . In it he proposed that natural selection could cause the reproductive isolation of two varieties by encouraging the development of barriers against hybridization, and thus contribute to the development of new species. He suggested the following scenario: When two varieties of a species had diverged beyond a certain point, each adapted to different conditions, hybrid offspring would be less well adapted than either parent form. At that point natural selection will tend to eliminate the hybrids. Under such conditions natural selection would also favor the development of barriers to hybridization, since individuals that avoided hybrid matings would tend to have more fit offspring. This would contribute to the reproductive isolation of the two incipient species. edit Current status Sometimes also called "reinforcement" or "heterozygote disadvantage", the Wallace effect continues to be a topic of research in

7. Alfred Russel Wallace (1823 - 1913) Is One Of The Forgotten Fathers Of Modern Sc An account of the trip to the Malay peninsula and Indonesia. http://www.iol.ie/~spice/alfred.htm

Alfred Russel Wallace Alfred Russel Wallace (1823 - 1913) is one of the forgotten fathers of modern science. He was born in the village of Usk in Monmouthshire, England. His father died when Alfred was young. Not long after formal schooling ended for Alfred. He joined his brother, William, in surveying a number of English counties over the next four years. This experience was to teach him how to make accurate observations and detailed recordings, skills which would be of immense importance in later life. Shortly after this, Wallace was appointed to the position of drawing-master at the Collegiate School in Leicester. It was here that he met Henry Walter Bates, a fellow teacher who introduced his young colleague to the methods and delights of botany. After two years the friends set out for South America on an expedition which would see them explore the Amazon and Rio Negro rivers. In order to cover a larger area Bates and Wallace split up. Wallace sent his collection of specimens to Para for storage in advance of transportation to England. He spent over four years in the tropical jungles of Brazil before setting sail for home in 1852. Disaster struck on the high seas. Wallace's ship caught fire and had to be abandoned in great haste. He lost his entire collection and most of his notes. Luckily, the crew and passengers were rescued by a passing vessel and, after further difficulties, arrived at Deal in an exhausted state. Such a calamity would have defeated a lesser person but Wallace turned his energies to writing an account of his time in Brazil
