Bernard Kettlewell
Henry Bernard Davis Kettlewell (24 February 1907 – 11 May 1979) was a British geneticist, lepidopterist and medical doctor, who performed research on the influence of industrial melanism on peppered moth (''Biston betularia'') coloration, showing why moths are darker in polluted areas. This experiment is cited as a classic demonstration of natural selection in action. After live video record of the experiment with Niko Tinbergen, Sewall Wright called the study as "the clearest case in which a conspicuous evolutionary process has actually been observed." Early life Kettlewell was born in Howden, Yorkshire, and educated at Charterhouse School. During 1926 he studied medicine and zoology at Gonville and Caius College, Cambridge. During 1929 he began clinical training at St Bartholomew's Hospital, London, then during 1935 joined a general medical practice in Cranleigh, Surrey. He also worked as an anaesthetist at St. Luke's Hospital, Guildford. During World War II, from 1939 to 19 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Howden, Yorkshire
Howden () is a market and minster town and civil parish in the East Riding of Yorkshire, England. It lies in the Vale of York to the north of the M62, on the A614 road about south-east of York and north of Goole, which lies across the River Ouse. William the Conqueror gave the town to the Bishops of Durham in 1080. The wapentake of Howdenshire was named after the town, and remained an exclave of County Durham until as late as 1846. The original boundaries of the wapentake were used for the current two government wards of Howden and Howdenshire, which had a combined population of 19,753 at the 2011 census. Geography Howden is situated in the Vale of York, on the A614, although the town itself has been bypassed. Howden lies close to the M62 and the M18 motorways, nearby to Goole which lies at the opposite side of the River Ouse. The town is served by Howden railway station, which is situated in North Howden and has services to Leeds, Selby, York, Hull and London. How ...

Industrial Melanism
Industrial melanism is an evolutionary effect prominent in several arthropods, where dark pigmentation (melanism) has evolved in an environment affected by industrial pollution, including sulphur dioxide gas and dark soot deposits. Sulphur dioxide kills lichens, leaving tree bark bare where in clean areas it is boldly patterned, while soot darkens bark and other surfaces. Darker pigmented individuals have a higher fitness in those areas as their camouflage matches the polluted background better; they are thus favoured by natural selection. This change, extensively studied by Bernard Kettlewell, is a popular teaching example in Darwinian evolution, providing evidence for natural selection. Kettlewell's results have been challenged by zoologists, creationists and the journalist Judith Hooper, but later researchers have upheld Kettlewell's findings. Industrial melanism is widespread in the Lepidoptera (butterflies and moths), involving over 70 species such as ''Odontopera bide ...

Woking
Woking ( ) is a town and borough status in the United Kingdom, borough in northwest Surrey, England, around from central London. It appears in Domesday Book as ''Wochinges'' and its name probably derives from that of a Anglo-Saxon settlement of Britain, Saxon landowner. The earliest evidence of human activity is from the Paleolithic, but the low fertility of the sandy, local soils meant that the area was the least populated part of the county in 1086. Between the mid-17th and mid-19th centuries, new transport links were constructed, including the Wey and Godalming Navigations, Wey Navigation, Basingstoke Canal and South West Main Line, London to Southampton railway line. The modern town was established in the mid-1860s, as the London Necropolis Company began to sell surplus land surrounding Woking railway station, the railway station for home construction, development. Modern local government in Woking began with the creation of the Woking Local Board of Health, Local Board in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Emergency Medical Services
Emergency medical services (EMS), also known as ambulance services or paramedic services, are emergency services that provide urgent pre-hospital treatment and stabilisation for serious illness and injuries and transport to definitive care. They may also be known as a first aid squad, FAST squad, emergency squad, ambulance squad, ambulance corps, life squad or by other initialisms such as EMAS or EMARS. In most places, the EMS can be summoned by members of the public (as well as medical facilities, other emergency services, businesses and authorities) via an emergency telephone number which puts them in contact with a control facility, which will then dispatch a suitable resource for the situation. Ambulances are the primary vehicles for delivering EMS, though some also use squad cars, motorcycles, aircraft, or boats. EMS agencies may also operate a non-emergency patient transport service, and some have rescue squads to provide technical rescue services. As a first resort ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Guildford
Guildford () is a town in west Surrey, around southwest of central London. As of the 2011 census, the town has a population of about 77,000 and is the seat of the wider Borough of Guildford, which had around inhabitants in . The name "Guildford" is thought to derive from a crossing of the River Wey, a tributary of the River Thames that flows through the town centre. The earliest evidence of human activity in the area is from the Mesolithic and Guildford is mentioned in the will of Alfred the Great from . The exact location of the main Anglo-Saxon settlement is unclear and the current site of the modern town centre may not have been occupied until the early 11th century. Following the Norman Conquest, a motte-and-bailey castle was constructed, which was developed into a royal residence by Henry III. During the late Middle Ages, Guildford prospered as a result of the wool trade and the town was granted a charter of incorporation by Henry VII in 1488. The River Wey Navig ...

Cranleigh
Cranleigh is a village and civil parish, about southeast of Guildford in Surrey, England. It lies on a minor road east of the A281, which links Guildford with Horsham. It is in the north-west corner of the Weald, a large remnant forest, the main local remnant being Winterfold Forest directly north-west on the northern Greensand Ridge. Etymology Until the mid-1860s, the place was usually spelt Cranley. The Post Office persuaded the vestry to use "''-leigh''" to avoid misdirections to nearby Crawley in West Sussex. The older spelling is publicly visible in the ''Cranley Hotel''. The name is recorded in the '' Pipe Rolls'' as ''Cranlea'' in 1166 and ''Cranelega'' in 1167. A little later in the '' Feet of Fines'' of 1198 the name is written as ''Cranele''. Etymologists consider all these versions to be the fusion of the Old English words "Cran", meaning " crane", and "Lēoh" that together mean 'a woodland clearing visited by cranes'. The name is popularly believed to come from imp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sewall Wright
Sewall Green Wright FRS(For) Honorary FRSE (December 21, 1889March 3, 1988) was an American geneticist known for his influential work on evolutionary theory and also for his work on path analysis. He was a founder of population genetics alongside Ronald Fisher and J. B. S. Haldane, which was a major step in the development of the modern synthesis combining genetics with evolution. He discovered the inbreeding coefficient and methods of computing it in pedigree animals. He extended this work to populations, computing the amount of inbreeding between members of populations as a result of random genetic drift, and along with Fisher he pioneered methods for computing the distribution of gene frequencies among populations as a result of the interaction of natural selection, mutation, migration and genetic drift. Wright also made major contributions to mammalian and biochemical genetics. Biography Sewall Wright was born in Melrose, Massachusetts to Philip Green Wright and Elizabeth ...

Niko Tinbergen
Nikolaas "Niko" Tinbergen (; ; 15 April 1907 – 21 December 1988) was a Dutch biologist and ornithologist who shared the 1973 Nobel Prize in Physiology or Medicine with Karl von Frisch and Konrad Lorenz for their discoveries concerning the organization and elicitation of individual and social behavior patterns in animals. He is regarded as one of the founders of modern ethology, the study of animal behavior. In 1951, he published ''The Study of Instinct'', an influential book on animal behaviour. In the 1960s, he collaborated with filmmaker Hugh Falkus on a series of wildlife films, including ''The Riddle of the Rook'' (1972) and ''Signals for Survival'' (1969), which won the Italia prize in that year and the American blue ribbon in 1971. Education and early life Born in The Hague, Netherlands, he was one of five children of Dirk Cornelis Tinbergen and his wife Jeannette van Eek.
