Donald Trump'due south ballot every bit the 45^th President of the United States has been marked by the brewing storms of racial conflicts. A rise in racial incidents ensued in the firsthand backwash of Trump's victory in November 2016. Since the beginning of 2017, over 100 bomb threats accept been made against Jewish community centers and schools. Trump's travel ban, signed in tardily January 2017, initially affected about 90,000 people from seven Middle Eastern countries; 87,000 of those banned were Muslims. Minorities such as American Muslims and blackness Americans take expressed fears over racial relations under Trump. Undeniably, the topic of race—and racism—has gripped America and the world throughout.

Over the terminal decade, there have been hopes that the US has go a post-racial gild, complimentary of racial prejudice and discrimination. However, the most contempo months indicate the contrary: race remains an incendiary issue. Race and racism are not new issues, but in today's 21^st century Trump-era, discussions nigh race are distinct from those of the past in that they possess an entirely new dimension: that of genetics and Deoxyribonucleic acid.

Race in the new era of homo genetics enquiry

In 2003, scientists completed the Human Genome Project, making it finally possible to examine human ancestry with genetics. Scientists have since tackled topics such as human migrations out of Africa and around the world. And it's non just scientists who are excited about human genetics: widely affordable at-dwelling house ancestry exam kits are now readily available from companies like 23andMe, Family Tree Deoxyribonucleic acid, and Ancestry. For $99—effectually the price of a romantic dinner or a pair of Nikes—a client tin can receive an assay from 23andMe indicating that they are, for example, 18.0% Native American, 65.one% European and 6.2% African.

The soaring popularity of beginnings testing bespeaks a widespread perception that we tin use these tests to dissect, delineate, and define our ancestral limerick. Indeed, social media is teeming with blog posts, and fifty-fifty livestream videos, from excited customers bursting to broadcast their test results and their reactions. Beginnings test kits are the new "it" item—and with their success is the tacit admission of our belief that our Deoxyribonucleic acid tin can sort united states of america into categories like the "five races:" African, European, Asian, Oceania, and Native American (Effigy 1A).

Effigy 1: 'Race' cannot exist biologically defined due to genetic variation among human individuals and populations. (A) The old concept of the "five races:" African, Asian, European, Native American, and Oceanian. According to this view, variation between the races is large, and thus, the each race is a separate category. Additionally, individual races are idea to have a relatively uniform genetic identity. (B) Bodily genetic variation in humans. Human populations practice roughly cluster into geographical regions. Still, variation between dissimilar regions is small, thus blurring the lines between populations. Furthermore, variation within a single region is large, and there is no compatible identity.

New findings in genetics tear down old ideas well-nigh race

Estimating our bequeathed composition down to 0.1% seem to suggest that there are verbal, chiselled divisions between human populations. But reality is far less simple. Compared to the general public's enthusiasm for beginnings testing, the reaction from scientists has been considerably more than lukewarm. Research indicates that the concept of "five races" does, to an extent, draw the style human populations are distributed among the continents—but the lines between races are much more blurred than ancestry testing companies would have us believe (Figure 1B).

A landmark 2002 study by Stanford scientists examined the question of homo diversity past looking at the distribution beyond seven major geographical regions of 4,000 alleles. Alleles are the different "flavors" of a factor. For case, all humans accept the same genes that lawmaking for hair: the different alleles are why hair comes in all types of colors and textures.

In the Stanford written report, over 92% of alleles were institute in ii or more regions, and almost half of the alleles studied were nowadays in all 7 major geographical regions. The ascertainment that the vast majority of the alleles were shared over multiple regions, or even throughout the entire world, points to the fundamental similarity of all people around the earth—an idea that has been supported by many other studies (Figure 1B).

If separate racial or ethnic groups really existed, we would expect to find "trademark" alleles and other genetic features that are characteristic of a single grouping but not present in any others. Notwithstanding, the 2002 Stanford report found that simply seven.4% of over 4000 alleles were specific to 1 geographical region. Furthermore, even when region-specific alleles did appear, they only occurred in about 1% of the people from that region—hardly enough to exist whatever kind of trademark. Thus, there is no evidence that the groups we usually call "races" have distinct, unifying genetic identities. In fact, there is ample variation within races (Figure 1B).

Ultimately, there is so much ambiguity between the races, and so much variation within them, that 2 people of European descent may be more genetically similar to an Asian person than they are to each other (Figure 2).

Figure 2: Case study of genetic variation between iii scientists. Left: Schematization of the genetic variation between Drs. James Watson, Craig Venter, and Kim Seong-jin. Colored confined correspond genes; different colors stand for unlike alleles, i.due east. versions of genes. Some alleles are shared by all three of the men (represented by the dark brown allele that is shared by every person in this image). Also the universal night brown allele, Watson and Venter share one other allele (bright blue). All the same, both share ii alleles with Kim (Watson shares red and orange with Kim, Venter shares dark-green and magenta), in improver to the universal allele. Correct: There is more than similarity between the Kim and Watson and Kim and Venter, than there is between Watson and Venter.

Does "race" still hateful something?

The divisions between races are doubtlessly blurred, but does this necessarily mean that race is a myth—a mere social construct and biologically meaningless? As with other race-related questions, the reply is multi-dimensional and may well depend on whom you ask.

In the biological and social sciences, the consensus is clear: race is a social construct, not a biological attribute. Today, scientists prefer to apply the term "beginnings" to describe human diversity (Figure iii). "Beginnings" reflects the fact that homo variations exercise have a connection to the geographical origins of our ancestors—with plenty information about a person's Deoxyribonucleic acid, scientists can make a reasonable guess near their beginnings. Still, dissimilar the term "race," it focuses on understanding how a person'due south history unfolded, non how they fit into i category and not another. In a clinical setting, for instance, scientists would say that diseases such every bit sickle-cell anemia and cystic fibrosis are mutual in those of "sub-Saharan African" or "Northern European" descent, respectively, rather than in those who are "black" or "white".

Figure 3: Race versus ancestry. (A) The classification of people into different races is typically based on observable physical features, with peel color being the well-nigh prominently used feature. Racial classifications too describe upon non-biological characteristics such as culture, language, history, organized religion, and socioeconomic status. Thus, "race" is a term that lacks clear definition. (B) In contrast to race, "ancestry" emphasizes the geographical origins of i's ancestors (parents, grandparents, and beyond). Unlike "race," the concept of "ancestry" does not focus on the static categorization of humans into groups, but rather on the process past which a person'south history unfolded.

However, even if scientists agree that race is, at most, a social construct, any cursory search of the net reveals that the broader public is not convinced of this. After all, if an Asian person looks and then unlike from a European, how could they not be from distinct groups? Even if well-nigh scientists reject the concept of "race" as a biological concept, race exists, undeniably, equally a social and political concept.

The popular classifications of race are based chiefly on skin color, with other relevant features including meridian, eyes, and hair. Though these physical differences may announced, on a superficial level, to be very dramatic, they are determined by just a infinitesimal portion of the genome: we as a species have been estimated to share 99.9% of our DNA with each other. The few differences that do exist reflect differences in environments and external factors, not core biology.

Chiefly, the evolution of skin color occurred independently, and did not influence other traits such as mental abilities and behavior. In fact, science has nevertheless to detect evidence that there are genetic differences in intelligence  between populations. Ultimately, while in that location certainly are some biological differences betwixt different populations, these differences are few and superficial. The traits that we do share are far more profound

Science and genetics: Instruments of modern racism

Despite the scientific consensus that humanity is more akin than different, the long history of racism is a somber reminder that throughout human history, a mere 0.1% of variation has been sufficient justification for committing all manner of discriminations and atrocities. The advances in human genetics and the evidence of negligible differences between races might be expected to halt racist arguments. But, in fact, genetics has been used to further racist and ethnocentric arguments—as in the example of the alt-correct, which promotes far-right ideologies, including white nationalism and anti-Semitism.

Considered a fringe movement for years, the alt-right gained considerable attention and relevance during Trump'south presidential campaign. Indeed, Steve Bannon, the current senior counselor and chief strategist to President Trump and the former chief executive officer of Trump's entrada, has notable ties to the alt-right. Once relegated to obscure cyberspace forums, the alt-right'south newest pulpit is the White Business firm.

Members of the alt-right are enthusiastic proponents of beginnings testing as a way to bear witness their "pure" white heritage (with Scandinavian and Germanic beginnings being among the most desirable) and to rule out undesired descent from any other groups (including, unsurprisingly, Africans and the Ashkenazi Jews, but even certain European groups, such as Italians and Armenians). The belief in white superiority, and the demand to preserve it, drives the alt-right motility—and genetics is both the weapon and battle standard of this new, supposedly "scientific" racism.

Those who disagree with alt-right ideologies may assume that the alt-right is but spewing ignorant nonsense. This is certainly truthful for some of the alt-right. What is possibly a more difficult truth is that many of the alt-correct practise, in fact, sympathize biology and genetics to an impressive extent, even if this understanding is flawed.

For instance, alt-right proponents accept stated, correctly, that many people with European and Asian descent accept inherited 1-4% of their Deoxyribonucleic acid from Neanderthals ancestors, and those of African descent exercise non have Neanderthal heritage. They are similarly correct that Neanderthals had larger skulls than humans. Based on these facts, some within the alt-correct have claimed that Europeans and Asians have superior intelligence because they accept inherited larger brains from their Neanderthal ancestors.

Even so, this claim ignores that while there is evidence for the outcome of Neanderthal Deoxyribonucleic acid on certain traits, there has been no evidence for its upshot on intelligence. Furthermore, scientific research indicates that the Neanderthals were not necessarily more intelligent simply because they had larger skulls. Unsurprisingly, the alt-right tends cherry-pick the ideas that align with their preconceived notions of racial hierarchies, ignoring the broader context of the field of man genetics.

Fighting racism with understanding

Just as the alt-right is no longer an easily dismissed fringe group, their arguments accept some factual basis, and cannot be swept aside as the babbling of the scientific illiterate. The alt-right is non impuissant in their employ of science and genetics in their battle for their "ideals." Those who oppose the alt-correct, and other racist entities, must arm themselves with the same weapons: education, namely scientific and genetic literacy.

Mounting scientific evidence has shown that humans are fundamentally more similar than different from each other. Nonetheless, racism has persisted. Scientific findings are oft ignored, or otherwise actively misinterpreted and misused to further racist agendas of extreme political groups. Opponents of these forces must, through their own education and sensation, combat these misleading interpretations and representations of scientific findings.

Today, the question of "race" is no longer just a political and social issue: as science has speedily advanced, it has become irrevocably intertwined. The genome contains powerful insights about our biology that could unite us every bit a species, but which could also be unsafe and divisive if used without understanding. Every bit we look forward to 2017 and onwards, it becomes ever more important to understand what our Deoxyribonucleic acid says near what it ways to be human being.
