In other words, the polygenic theory of races is proof of the two processes that make up scientific racism. On the one hand, it exemplifies how scientific research can be easily exploited to legitimize and reproduce stereotypes and conditions of inequality, discrimination or violence towards minorities, in this case racialized.
However, superficial polygenic traits like skin color cannot be easily associated with other traits, such as cognitive traits, in the way racist essentialism would espouse.
Polygenism is a theory of human origins which posits the view that the human races are of different origins (polygenesis).This view is opposite to the idea of monogenism, which posits a single origin of humanity.Modern scientific views no longer favor the polygenic model, with the monogenic "Out of Africa" theory and its variants being the most widely accepted models for human origins.
Polygenic traits are the characteristics of an organism that are due to more than one gene. Simple Mendelian inheritance is valid for a single gene, but most traits are caused by the influence of many genes. Polygenic traits can vary continuously and may also be influenced by environmental factors.
Consequently, in using polygenic scores to describe genomic contributions to traits, particularly traits for which the total contribution of genetic variation to trait variation, as measured by heritability, is low—but even if it is high (Fig. 1E)—a difference in polygenic scores between populations provides little information about ...
Polygenic traits also have dominant and recessive alleles, but so many genes play a role in an organism’s phenotype for these traits that the final result is the sum of many complex interactions. It can be hard or impossible to figure out one gene’s effect on a polygenic trait.
Today, the fact that people of non-European descent are going to miss out on the medical benefits of GWAS-derived polygenic risk scores is itself a manifestation of racism in biomedical research. Those scientists who want to draw attention to the racial bias in genetic research but who don’t want to acknowledge the scientific validity of race ...
An alternative view is that racism (and xenophobia of all kinds) does not have a genetic or evolutionary basis, but is primarily a psychological trait — more specifically, a psychological ...
The following AAPA Statement on Race and Racism was written by the AAPA subcommittee tasked with revising the previous AAPA statement on the Biological Aspects of Race that was published in the American Journal of Physical Anthropology, vol. 101, pp 569-570, 1996.The Committee on Diversity (COD) subcommittee was comprised of (in alpha order): Rebecca Ackermann, Sheela Athreya, Deborah Bolnick ...
Darwin was, after all, a man of his time, class and society. True, he was committed to a monogenic, rather than the prevailing polygenic, view of human origins, but he still divided humanity into distinct races according to differences in skin, eye or hair colour.
