Survival of the fittest WikipediaSurvival of the fittest is a phrase that originated from Darwinian evolutionary theory as a way of describing the mechanism of natural selection. The biological concept of fitness is defined as reproductive success. Iptv Hack. In Darwinian terms the phrase is best understood as Survival of the form that will leave the most copies of itself in successive generations. Herbert Spencer first used the phrase, after reading Charles Darwins On the Origin of Species, in his Principles of Biology 1. Darwins biological ones This survival of the fittest, which I have here sought to express in mechanical terms, is that which Mr. Darwin has called natural selection, or the preservation of favoured races in the struggle for life. Darwin responded positively to Alfred Russel Wallaces suggestion of using Spencers new phrase survival of the fittest as an alternative to natural selection, and adopted the phrase in The Variation of Animals and Plants under Domestication published in 1. In On the Origin of Species, he introduced the phrase in the fifth edition published in 1. Critiquing the phrase survival of the fittesteditWhile the phrase survival of the fittest is often used to refer to natural selection, it is avoided by modern biologists, because the phrase can be misleading. For example, survival is only one aspect of selection, and not always the most important. Another problem is that the word fit is frequently confused with a state of physical fitness. In the evolutionary meaning fitness is the rate of reproductive output among a class of genetic variants. Interpreted as expressing a biological theoryeditThe phrase can also be interpreted to express a theory or hypothesis that fit as opposed to unfit individuals or species, in some sense of fit, will survive some test. Interpretations of the phrase as expressing a theory are in danger of being tautological, meaning roughly those with a propensity to survive have a propensity to survive to have content the theory must use a concept of fitness that is independent of that of survival. Interpreted as a theory of species survival, the theory that the fittest species survive is undermined by evidence that while direct competition is observed between individuals, populations and species, there is little evidence that competition has been the driving force in the evolution of large groups such as, for example, amphibians, reptiles, and mammals. Instead, these groups have evolved by expanding into empty ecological niches. In the punctuated equilibrium model of environmental and biological change, the factor determining survival is often not superiority over another in competition but ability to survive dramatic changes in environmental conditions, such as after a meteor impact energetic enough to greatly change the environment globally. The main land dwelling animals to survive the K Pg impact 6. In 2. 01. 0 Sahney et al. Instead, they cited extrinsic, abiotic factors such as expansion as the driving factor on a large evolutionary scale. The rise of dominant groups such as amphibians, reptiles, mammals and birds occurred by opportunistic expansion into empty ecological niches and the extinction of groups happened due to large shifts in the abiotic environment. Interpreted as expressing a moral theoryeditSocial DarwinistseditIt has been claimed that the survival of the fittest theory in biology was interpreted by late 1. Darwinism which was used to justify laissez faire economics, war and racism. However, these ideas predate and commonly contradict Darwins ideas, and indeed their proponents rarely invoked Darwin in support. The term social Darwinism referring to capitalist ideologies was introduced as a term of abuse by Richard Hofstadters Social Darwinism in American Thought published in 1. CreationistseditCritics of theories of evolution have argued that survival of the fittest provides a justification for behaviour that undermines moral standards by letting the strong set standards of justice to the detriment of the weak. However, any use of evolutionary descriptions to set moral standards would be a naturalistic fallacy or more specifically the isought problem, as prescriptive moral statements cannot be derived from purely descriptive premises. Describing how things are does not imply that things ought to be that way. It is also suggested that survival of the fittest implies treating the weak badly, even though in some cases of good social behaviour  co operating with others and treating them well  might improve evolutionary fitness. AnarchistseditRussian anarchist Peter Kropotkin viewed the concept of survival of the fittest as supporting co operation rather than competition. In his book Mutual Aid A Factor of Evolution he set out his analysis leading to the conclusion that the fittest was not necessarily the best at competing individually, but often the community made up of those best at working together. He concluded that. In the animal world we have seen that the vast majority of species live in societies, and that they find in association the best arms for the struggle for life understood, of course, in its wide Darwinian sense not as a struggle for the sheer means of existence, but as a struggle against all natural conditions unfavourable to the species. The animal species, in which individual struggle has been reduced to its narrowest limits, and the practice of mutual aid has attained the greatest development, are invariably the most numerous, the most prosperous, and the most open to further progress. Applying this concept to human society, Kropotkin presented mutual aid as one of the dominant factors of evolution, the other being self assertion, and concluded that. In the practice of mutual aid, which we can retrace to the earliest beginnings of evolution, we thus find the positive and undoubted origin of our ethical conceptions and we can affirm that in the ethical progress of man, mutual support not mutual struggle has had the leading part. In its wide extension, even at the present time, we also see the best guarantee of a still loftier evolution of our race. History of the phraseeditHerbert Spencer first used the phrase after reading Charles Darwins On the Origin of Species  in his Principles of Biology of 1. Darwins biological, evolutionary ones, writing, This survival of the fittest, which I have here sought to express in mechanical terms, is that which Mr. Darwin has called natural selection, or the preservation of favored races in the struggle for life. In July 1. Alfred Russel Wallace wrote to Darwin about readers thinking that the phrase natural selection personified nature as selecting, and said this misconception could be avoided by adopting Spencers term Survival of the fittest. Darwin promptly replied that Wallaces letter was as clear as daylight. I fully agree with all that you say on the advantages of H. Spencers excellent expression of the survival of the fittest. This however had not occurred to me till reading your letter. It is, however, a great objection to this term that it cannot be used as a substantive governing a verb.
