accurate representation of human biological variation. It was never accurate in the past, and it remains inaccurate when referencing contemporary human populations. Humans are not divided biologically into distinct continental types or racial genetic clusters. Instead, the Western concept of race must be understood as a classification system that emerged from, and in support of, European colonialism, oppression, and discrimination.Wagner et al. (2017) surveyed 3,286 American anthropologists' views on race and genetics, including both cultural and biological anthropologists. They found a consensus among them that biological races do not exist in humans, but that race does exist insofar as the social experiences of members of different races can have significant effects on health. Wang, Štrkalj et al. (2003) examined the use of race as a biological concept in research papers published in China's only biological anthropology journal, Acta Anthropologica Sinica. The study showed that the race concept was widely used among Chinese anthropologists. In a 2007 review paper, Štrkalj suggested that the stark contrast of the racial approach between the United States and China was due to the fact that race is a factor for social cohesion among the ethnically diverse people of China, whereas "race" is a very sensitive issue in America and the racial approach is considered to undermine social cohesion – with the result that in the socio-political context of US academics scientists are encouraged not to use racial categories, whereas in China they are encouraged to use them. Lieberman et al. in a 2004 study researched the acceptance of race as a concept among anthropologists in the United States, Canada, the Spanish speaking areas, Europe, Russia and China. Rejection of race ranged from high to low, with the highest rejection rate in the United States and Canada, a moderate rejection rate in Europe, and the lowest rejection rate in Russia and China. Methods used in the studies reported included questionnaires and content analysis. Kaszycka et al. (2009) in 2002–2003 surveyed European anthropologists' opinions toward the biological race concept. Three factors, country of academic education, discipline, and age, were found to be significant in differentiating the replies. Those educated in Western Europe, physical anthropologists, and middle-aged persons rejected race more frequently than those educated in Eastern Europe, people in other branches of science, and those from both younger and older generations." The survey shows that the views on race are sociopolitically (ideologically) influenced and highly dependent on
