paragraph_text: Scientific racism
  
  The modern biological definition of race developed in the 19th century with scientific racist theories. The term scientific racism refers to the use of science to justify and support racist beliefs, which goes back to the early 18th century, though it gained most of its influence in the mid-19th century, during the New Imperialism period. Also known as academic racism, such theories first needed to overcome the Church 's resistance to positivist accounts of history and its support of monogenism, the concept that all human beings were originated from the same ancestors, in accordance with creationist accounts of history.
  
  These racist theories put forth on scientific hypothesis were combined with unilineal theories of social progress, which postulated the superiority of the European civilization over the rest of the world. Furthermore, they frequently made use of the idea of " survival of the fittest ", a term coined by Herbert Spencer in 1864, associated with ideas of competition, which were named social Darwinism in the 1940s. Charles Darwin himself opposed the idea of rigid racial differences in The Descent of Man (1871), in which he argued that humans were all of one species, sharing common descent. He recognised racial differences as varieties of humanity, and emphasised the close similarities between people of all races in mental faculties, tastes, dispositions and habits, while still contrasting the culture of the "lowest savages" with European civilization.
  
  At the end of the 19th century, proponents of scientific racism intertwined themselves with eugenics discourses of " degeneration of the race" and "blood heredity ". Henceforth, scientific racist discourses could be defined as the combination of polygenism, unilinealism, social Darwinism, and eugenism. They found their scientific legitimacy on physical anthropology, anthropometry, craniometry, phrenology, physiognomy, and others now discredited disciplines in order to formulate racist prejudices.
  
  Before being disqualified in the 20th century by the American school of cultural anthropology (Franz Boas, etc.), the British school of social anthropology (Bronisław Malinowski, Alfred Radcliffe-Brown, etc.), the French school of ethnology (Claude Lévi-Strauss, etc.), as well as the discovery of the neo-Darwinian synthesis, such sciences, in particular anthropometry, were used to deduce behaviours and psychological characteristics from outward, physical appearances.
  
  The neo-Darwinian synthesis, first developed in the 1930s, eventually led to a gene-centered view of evolution in the 1960s. According to the Human Genome Project, the most complete mapping of human DNA to date indicates that there is no clear genetic basis to racial groups. While some genes are more common in certain populations, there are no genes that exist in all members of one population and no members of any other.
