Donald Trump's election as 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 immediate aftermath of Trump's victory in November 2016. Since the beginning of 2017, over 100 bomb threats have been fabricated against Jewish community centers and schools. Trump's travel ban, signed in late Jan 2017, initially affected about 90,000 people from seven Middle Eastern countries; 87,000 of those banned were Muslims. Minorities such equally American Muslims and black Americans take expressed fears over racial relations nether Trump. Undeniably, the topic of race—and racism—has gripped America and the world throughout.

Over the last decade, there have been hopes that the US has become a post-racial order, free of racial prejudice and bigotry. However, the most recent months indicate the contrary: race remains an incendiary result. Race and racism are non new issues, but in today's 21^st century Trump-era, discussions about race are distinct from those of the by in that they possess an entirely new dimension: that of genetics and DNA.

Race in the new era of human genetics research

In 2003, scientists completed the Human Genome Projection, making it finally possible to examine human ancestry with genetics. Scientists accept since tackled topics such every bit man migrations out of Africa and around the world. And it's not but scientists who are excited most homo genetics: widely affordable at-home ancestry test kits are now readily available from companies like 23andMe, Family Tree DNA, and Ancestry. For $99—around the price of a romantic dinner or a pair of Nikes—a customer tin can receive an analysis from 23andMe indicating that they are, for instance, 18.0% Native American, 65.one% European and half-dozen.ii% African.

The soaring popularity of beginnings testing bespeaks a widespread perception that nosotros can utilize these tests to dissect, delineate, and ascertain our ancestral composition. Indeed, social media is teeming with blog posts, and even livestream videos, from excited customers bursting to broadcast their test results and their reactions. Ancestry examination kits are the new "it" item—and with their success is the tacit access of our belief that our Dna can sort u.s.a. into categories like the "five races:" African, European, Asian, Oceania, and Native American (Figure 1A).

Figure one: 'Race' cannot be biologically defined due to genetic variation amongst man individuals and populations. (A) The erstwhile concept of the "five races:" African, Asian, European, Native American, and Oceanian. According to this view, variation betwixt the races is big, and thus, the each race is a separate category. Additionally, individual races are thought to have a relatively uniform genetic identity. (B) Actual genetic variation in humans. Human being populations do roughly cluster into geographical regions. However, variation between different regions is small-scale, thus blurring the lines betwixt populations. Furthermore, variation within a single region is large, and there is no compatible identity.

New findings in genetics tear downwardly old ideas most race

Estimating our ancestral limerick down to 0.1% seem to suggest that at that place are exact, categorical divisions between human populations. But reality is far less simple. Compared to the general public'southward enthusiasm for ancestry testing, the reaction from scientists has been considerably more lukewarm. Inquiry indicates that the concept of "5 races" does, to an extent, draw the way human populations are distributed among the continents—but the lines betwixt races are much more blurred than ancestry testing companies would accept us believe (Effigy 1B).

A landmark 2002 report by Stanford scientists examined the question of homo diverseness by looking at the distribution across vii major geographical regions of 4,000 alleles. Alleles are the different "flavors" of a gene. For instance, all humans take the same genes that lawmaking for pilus: the different alleles are why pilus comes in all types of colors and textures.

In the Stanford study, over 92% of alleles were found in two or more regions, and almost half of the alleles studied were present in all seven major geographical regions. The ascertainment that the vast majority of the alleles were shared over multiple regions, or fifty-fifty throughout the entire globe, points to the fundamental similarity of all people around the globe—an thought that has been supported by many other studies (Figure 1B).

If separate racial or indigenous groups actually existed, we would wait to find "trademark" alleles and other genetic features that are characteristic of a single group simply not present in any others. All the same, the 2002 Stanford study found that merely 7.iv% of over 4000 alleles were specific to 1 geographical region. Furthermore, even when region-specific alleles did appear, they only occurred in almost 1% of the people from that region—hardly plenty to be whatsoever kind of trademark. Thus, in that location is no testify that the groups we commonly telephone call "races" have distinct, unifying genetic identities. In fact, there is ample variation inside races (Figure 1B).

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

Effigy 2: Instance study of genetic variation between three scientists. Left: Schematization of the genetic variation between Drs. James Watson, Craig Venter, and Kim Seong-jin. Colored bars represent genes; different colors represent different alleles, i.e. versions of genes. Some alleles are shared past all three of the men (represented past the dark brown allele that is shared by every person in this paradigm). Besides the universal dark brownish allele, Watson and Venter share one other allele (bright blueish). However, both share two alleles with Kim (Watson shares red and orange with Kim, Venter shares green and magenta), in addition to the universal allele. Right: At that place is more than similarity between the Kim and Watson and Kim and Venter, than there is between Watson and Venter.

Does "race" all the same mean something?

The divisions between races are doubtlessly blurred, but does this necessarily hateful that race is a myth—a mere social construct and biologically meaningless? Every bit with other race-related questions, the answer is multi-dimensional and may well depend on whom y'all ask.

In the biological and social sciences, the consensus is clear: race is a social construct, not a biological attribute. Today, scientists adopt to use the term "ancestry" to describe human being diversity (Effigy 3). "Beginnings" reflects the fact that homo variations do accept a connectedness to the geographical origins of our ancestors—with enough information about a person's DNA, scientists can make a reasonable guess nigh their ancestry. However, unlike the term "race," it focuses on understanding how a person'due south history unfolded, not how they fit into one category and not another. In a clinical setting, for case, scientists would say that diseases such as sickle-prison cell anemia and cystic fibrosis are common in those of "sub-Saharan African" or "Northern European" descent, respectively, rather than in those who are "blackness" or "white".

Figure 3: Race versus ancestry. (A) The classification of people into different races is typically based on observable physical features, with skin color being the near prominently used characteristic. Racial classifications likewise describe upon non-biological characteristics such as culture, linguistic communication, history, faith, and socioeconomic condition. Thus, "race" is a term that lacks articulate definition. (B) In contrast to race, "ancestry" emphasizes the geographical origins of one's ancestors (parents, grandparents, and across). Different "race," the concept of "beginnings" does non focus on the static categorization of humans into groups, but rather on the process by which a person's history unfolded.

Nevertheless, 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 so different from a European, how could they not exist from distinct groups? Even if most scientists pass up the concept of "race" every bit a biological concept, race exists, undeniably, as a social and political concept.

The popular classifications of race are based chiefly on skin color, with other relevant features including superlative, optics, and hair. Though these physical differences may announced, on a superficial level, to be very dramatic, they are determined by but a infinitesimal portion of the genome: nosotros every bit a species accept been estimated to share 99.9% of our Dna with each other. The few differences that practise exist reverberate differences in environments and external factors, non core biology.

Importantly, the evolution of skin color occurred independently, and did not influence other traits such as mental abilities and behavior. In fact, scientific discipline has yet to discover evidence that at that place are genetic differences in intelligence  between populations. Ultimately, while there certainly are some biological differences between different populations, these differences are few and superficial. The traits that we do share are far more profound

Scientific discipline and genetics: Instruments of mod racism

Despite the scientific consensus that humanity is more alike than unlike, the long history of racism is a somber reminder that throughout human being history, a mere 0.one% of variation has been sufficient justification for committing all manner of discriminations and atrocities. The advances in human genetics and the prove of negligible differences between races might be expected to halt racist arguments. Only, in fact, genetics has been used to further racist and ethnocentric arguments—as in the case of the alt-correct, which promotes far-right ideologies, including white nationalism and anti-Semitism.

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

Members of the alt-right are enthusiastic proponents of ancestry testing as a way to prove their "pure" white heritage (with Scandinavian and Germanic ancestry being among the about desirable) and to dominion out undesired descent from any other groups (including, unsurprisingly, Africans and the Ashkenazi Jews, but fifty-fifty certain European groups, such as Italians and Armenians). The belief in white superiority, and the demand to preserve it, drives the alt-right movement—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 simply spewing ignorant nonsense. This is certainly truthful for some of the alt-right. What is perhaps a more difficult truth is that many of the alt-right exercise, in fact, sympathize biological science and genetics to an impressive extent, fifty-fifty if this understanding is flawed.

For instance, alt-right proponents have stated, correctly, that many people with European and Asian descent have inherited 1-4% of their Deoxyribonucleic acid from Neanderthals ancestors, and those of African descent do not have Neanderthal heritage. They are similarly correct that Neanderthals had larger skulls than humans. Based on these facts, some inside the alt-correct have claimed that Europeans and Asians take superior intelligence considering they have inherited larger brains from their Neanderthal ancestors.

However, this claim ignores that while at that place is evidence for the result of Neanderthal Dna on sure traits, at that place has been no evidence for its effect on intelligence. Furthermore, scientific research indicates that the Neanderthals were not necessarily more than intelligent merely considering they had larger skulls. Unsurprisingly, the alt-correct tends cherry-option the ideas that align with their preconceived notions of racial hierarchies, ignoring the broader context of the field of human genetics.

Fighting racism with understanding

Just as the alt-right is no longer an easily dismissed fringe group, their arguments have some factual basis, and cannot exist swept bated equally the babbling of the scientific illiterate. The alt-right is not clumsy in their use of science and genetics in their battle for their "ideals." Those who oppose the alt-right, and other racist entities, must arm themselves with the same weapons: teaching, namely scientific and genetic literacy.

Mounting scientific evidence has shown that humans are fundamentally more than similar than different from each other. Nonetheless, racism has persisted. Scientific findings are often ignored, or otherwise actively misinterpreted and misused to further racist agendas of extreme political groups. Opponents of these forces must, through their ain instruction and awareness, 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 rapidly advanced, it has get irrevocably intertwined. The genome contains powerful insights about our biology that could unite us as a species, but which could also be dangerous and divisive if used without understanding. As nosotros expect forward to 2017 and onwards, it becomes ever more of import to understand what our DNA says nearly what it means to be human being.
