And if you’re wondering whether this is something controversial in the scientific community, the statement goes on to say that the fact that there are no completely separate races is supported by decades of research, including six recent studies like the 2017 paper from the Center for Research on Genomics and Global Health, directly titled “Human ancestry correlates with language and reveals that race is not an objective genomic classifier”.

Race, according to the scientists, is a “social construct” that is derived from people self-identifying with races based on physical appearance. Furthermore, there is no genetics-based support for claiming one group superior to another, expound the researchers.
The need for actual geneticists to take a stand is driven by the spread of racial purity myths that have been soundly disproven by science. Unexpectedly, one such strange idea taking hold relates to drinking milk.Some white nationalists believe that the ability to digest lactose in milk is somehow a characteristic of racial identity.
The American Society of Human Genetics (ASHG) is alarmed to see a societal resurgence of groups rejecting the value of genetic diversity and using discredited or distorted genetic concepts to bolster bogus claims of white supremacy. ASHG denounces this misuse of genetics to feed racist ideologies. In public dialog, our research community should be clear about genetic knowledge related to ancestry and genomic diversity. To that end, ASHG affirms the following:•Genetics demonstrates that humans cannot be divided into biologically distinct subcategories. Although there are clear observable correlations between variation in the human genome and how individuals identify by race, the study of human genetics challenges the traditional concept of different races of humans as biologically separate and distinct. This is validated by many decades of research, including recent examples.

Most human genetic variation is distributed as a gradient, so distinct boundaries between population groups cannot be accurately assigned.
There is considerable genetic overlap among members of different populations.
Such patterns of genome variation are explained by patterns of migration and mixing of different populations throughout human history.
In this way, genetics exposes the concept of “racial purity” as scientifically meaningless.
