Reverse genetic systems are a critical tool for studying viruses and identifying countermeasures. The reverse genetic system can be used to rapidly engineer viruses with desired mutations to study the virus in vitro and in vivo. Viruses can also be designed for live-attenuated vaccine development and engineered with reporter genes to facilitate serodiagnosis, vaccine evaluation and antiviral screening.

Early advocates of eugenics in the 19th century regarded it as a way of improving groups of people. In contemporary usage, the term eugenics is closely associated with scientific racism and white supremacy. While eugenic principles have been practiced as early as ancient Greecethe contemporary history of eugenics began in the early 20th century, when a popular eugenics movement emerged in the United Kingdom Gdnetic, [6] and then spread to many countries, including the United StatesCanada, [7] and most European countries.

Introduction

In this period, people from across the political spectrum espoused eugenic ideas. Consequently, many countries adopted eugenic policies, intended to improve the quality of their populations' genetic read more. Such programs included both positive measures, such as encouraging individuals deemed particularly "fit" to reproduce, The Dangers Of Genetic Engineering The Nature negative measures, such as marriage prohibitions and forced sterilization of people deemed unfit for reproduction. Those deemed "unfit to reproduce" often included people with mental or physical disabilitiespeople who scored in the low ranges on different IQ testscriminals and "deviants", and members of disfavored minority groups. The eugenics movement became associated with Nazi Germany and the Holocaust when the defense of The Dangers Of Genetic Engineering The Nature of the defendants at the Nuremberg trials of to attempted to justify their human-rights abuses by claiming there was little difference between the Nazi eugenics programs and the U.

Since the s and s, with new assisted reproductive technology procedures available, such as gestational surrogacy available sincepreimplantation genetic diagnosis available sinceand cytoplasmic transfer first performed inconcern has grown about the possible revival of a more potent form of eugenics after decades of promoting human rights. A criticism of eugenics policies is that, regardless of whether negative or positive policies are used, they are susceptible to abuse because the genetic selection criteria are determined by whichever group has political power at the time. Another criticism is that eugenics policies eventually lead to a loss of genetic diversitythereby resulting in inbreeding depression due to a loss of genetic variation.

Types of eugenic practices have existed for millennia. Some indigenous peoples of Brazil are known to have practiced infanticide against children born with physical abnormalities since precolonial times. In the early years of the Roman Republica Roman father was obliged by law to immediately kill his child if they were "dreadfully deformed".

The idea of a modern project for improving the human population through selective breeding was originally developed by Francis Galtonand was initially inspired by Darwinism and its theory of natural selection. Based on his biographical studies, Galton believed that desirable human qualities were hereditary traits, although Darwin strongly disagreed with this elaboration of his theory. Many of the early geneticists were not Darwinians, and evolution theory was not needed for eugenics policies based on genetic determinism. Eugenics became an academic discipline at many colleges and universities and received funding from many sources. Both sought support from leading clergymen and modified their message to meet religious ideals.

Although influential, the book was largely ignored when it first appeared, and it went through several revisions and editions. Nevertheless, the book was used by people who advocated restricted immigration as justification for what became known as " scientific racism ". Three International Eugenics Conferences presented a global venue for eugenists with meetings in in London, and in and in New York City.

Eugenic policies were first implemented in the early s in the United States.

Frederick Osborn 's journal article "Development of a Eugenic Philosophy" framed it as a social philosophy —a philosophy with implications for social order. Osborn advocated for higher rates of sexual reproduction among people with desired traits "positive eugenics" or reduced rates of sexual reproduction or sterilization of people with less-desired or undesired traits "negative eugenics".

In addition to being practiced in a number of countries, eugenics was internationally organized through the International Federation of Eugenics Organizations. Winston Churchill supported the British Eugenics Society and was an honorary vice president for the organization. Churchill believed that eugenics https://amazonia.fiocruz.br/scdp/essay/is-lafayette-a-hidden-ivy/the-science-of-the-signs.php solve "race deterioration" and reduce crime Naturr poverty.

Early critics of the philosophy of eugenics included the American sociologist Lester Frank Ward[46] the English writer G. Chestertonthe German-American anthropologist Franz Boaswho argued that advocates of eugenics greatly over-estimate the influence of biology, [47] and Scottish tuberculosis pioneer and author Halliday Sutherland. Ward's article " Eugenics, Euthenics, and Eudemics ", Chesterton's book Eugenics and Other Evilsand Boas' article " Eugenics " published in The Scientific Monthly were all harshly critical of the rapidly growing movement. Sutherland identified eugenists as a major obstacle to the eradication and cure of tuberculosis in his address "Consumption: Its Cause and Cure", [48] and criticism of eugenists and Neo- Malthusians in his book Birth Control led to a writ for libel from the eugenist Marie Stopes. Several biologists were also antagonistic to the eugenics movement, including Lancelot Hogben. TThe and R. Fisher expressed click here in the belief that sterilization of "defectives" would lead to the disappearance of undesirable genetic traits.

Among institutions, the Catholic Church was an opponent of state-enforced sterilizations. As a social movement, eugenics reached its greatest popularity in the early Thr of the 20th century, when it was practiced around the world and promoted by governments, institutions, and influential individuals.
