Since the 1950 UNESCO Statement on Race there has been an increasing tendency to claim, based on Boasian anthropology and in promotion of a multiracialist agenda, that the human races are "socially constructed" and their existence is not supported by science, meaning not biologically and genetically real. This essay is an account, consistent with current scientific knowledge, of how the human races we know historically and today were really constructed.
The human species is blessed with great variety and diversity. Its rich diversity resulted from its global distribution, which caused the different populations of humanity to be geographically separated and thus reproductively isolated. Reproductive isolation enabled divergence -- the process of divergent evolution -- to occur, causing the isolated populations to evolve in different directions, developing their own distinct ensembles of genetic traits and characteristics.
Divergent evolution is the process by which new life forms are created by the division and separation of life into different branches. Human evolution has seen its share of divergent branching. The generic name commonly used to refer to the genetically different populations, branches or divisions of humanity -- that share both a common biological ancestry and an ensemble of unique, genetically transmitted traits and characteristics which distinguish them from other populations -- is "race." But in the human species, as in any species enjoying a great degree of variety, the constant branching and dividing that characterizes the process of divergent evolution has created many different levels of branches and divisions, each of which possesses genetic traits which distinguish it from other branches or divisions at the same level. For purposes of taxonomic accuracy each of these levels should have its own specific name and definition. The first or highest level is called the species, and it is simply and objectively defined as including all those populations which are capable of interbreeding with each other and producing fully fertile offspring, and which do in fact interbreed under conditions of close and extensive contact. The term race is commonly used to refer to a branch or division of the species possessing genetically transmitted physical traits which distinguish it from other branches or divisions of the same level. Adding to this definition, it will here also be defined as including only those persons who are capable of reproduction with each other without the loss or significant diminishment or alteration of the racially-distinctive genetic traits of either parent stock. The genetically transmitted traits which distinguish a race from other divisions at the same level (i.e., other races) should not be diminished or lost by reproduction within the race. If racially-distinctive traits are lost or diminished by within-group reproduction then the population group is at a level of division too broad and inclusive to be accurately defined as a race. If it is too narrow to be defined as a species, as it does not include all those populations capable of interbreeding, then it is at a level between race and species, which will here be referred to as a subspecies.
The closest living relative of humanity, the still existing species most closely related to Homo sapiens, is the Chimpanzee, whose ancestral line separated and branched from the line leading to humans about 5.5 million years ago. Even after 5.5 million years of divergent evolution humans and chimpanzees still have over 98% of their genes in common, with only a 1.23% (Time, October 9, 2006) to 1.6% difference in their genome. The genus Homo originated with Homo habilis in the region of the Great Rift Valley in Kenya and Ethiopia in east Africa about two million years ago, where it continued to evolve, first as Homo ergaster and Homo erectus, then as Homo antecessor (750,000 years ago) and Homo heidelbergensis (600,000-250,000 years ago; believed to be the direct ancestor of Homo neanderthalensis in western Eurasia), and then as Homo sapiens idaltu, the earliest modern humans, with finds in Ethiopia dated to 195,000 and 160,000 years ago (Scientific American, Vol. 16, No. 2, 2006, p. 78).
The current (2019) general consensus is that there were at least three major migrations or expansions of the genus Homo out of east Africa into Eurasia, either crossing the Sinai peninsula from Egypt into the Levant (the coast of what is now Israel, Lebanon and Syria), or crossing the southern entrance of the Red Sea (the Bab el Mandeb) from Djibouti in Africa to Yemen in Asia, from where they spread throughout most of Eurasia and developed into a variety of regional "archaic" human populations. The first of these major expansions out of east Africa into Eurasia was about 1.8 million years ago, the second about 600,000 years ago (associated with the spread of the Acheulean culture), and the last shortly after 100,000 years ago. Beginning in 1987, based on genetic studies showing that the mitochondrial DNA (mtDNA) and the Y-chromosome of all living humans is derived from the last of these major expansions, the common view expressed in the popular press (called "Out-of-Africa") has been that the modern humans of the final migration completely replaced the regional archaic human populations from the first two major expansions. But beginning circa 2002 genetic studies by Alan Templeton and others have increasingly supported the view (called "Out-of-Africa-Again-and-Again") that although all our surviving mtDNA and Y-chromosome lineages as well as the majority of our other genes derive from the most recent expansion, a significant minority of our other genes have much older "coalescence" dates and must therefore derive from the regional archaic human populations of the first two major expansions. These studies indicate that some genes from the regional populations of the first expansion were assimilated and perpetuated by the populations of the second expansion, and that some of the genes of both of the first two (archaic) expansions were assimilated by the modern humans of the final expansion.
The first dispersal of modern humans probably began soon after the emergence of Homo sapiens idaltu in east Africa about 195,000 years ago, with some populations heading west into the tropical forest of the Congo basin where they intermixed with local archaic elements and evolved into the Congoid subspecies, others remaining in east Africa where they evolved into the Capoid or Khoisanid (San-Bushmen) subspecies, and others moving north to the shores of the Red Sea, where they became the progenitors of the population that eventually migrated out of Africa and populated the rest of the world, intermixing with regional archaic human populations they encountered in varying degrees, and evolving into the Australoid, Mongoloid and Caucasoid subspecies. By 130,000 years ago there were perhaps 10,000 modern humans living in different populations in different regions of Africa. About 120,000 years ago one of these modern human populations that had expanded up the Nile valley crossed the Sinai peninsula out of Africa into the Levant but no traces have been found of them after 90,000 years ago.
The final major expansion out of east Africa into Eurasia, perhaps numbering only a few hundred people at the beginning, crossed from northeast Africa to southwest Asia after 90,000 years ago, where they engaged in some intermixture with the local archaic Neanderthal groups. The descendants of this population gradually expanded and dispersed, with the initial expansion being along the southern coast of Asia. The where and when of these early human migrations was largely determined by geography, especially changes in climate and sea level. The first main split or division in the expansion occurred when some groups continued to move east while others remained in southwest Asia. The second main branching or division probably occurred after the eastward migrating group reached southeast Asia and intermixed with local archaic Denisovan elements, with one branch continuing to move eastward, reaching southern China by 68,000 years ago, where it experienced additional archaic Denisovan intermixture, and another branch remaining in the Burma-Thailand region, where it evolved into a proto-Australoid population, then expanded south through Malaysia and Indonesia, reaching New Guinea by 77,000 years ago and Australia by 65,000 years ago.
The eruption, or explosion, of the Toba super-volcano in northern Sumatra circa 74,000 years ago, the largest such explosion in the last two million years, perhaps 100 times larger than the Krakatoa event off southern Sumatra in 1883, covered the entire Indian sub-continent in several meters of ash, probably destroying almost all life, including the early human population in the area. The populations to the east and south of the eruption were spared its catastrophic effects, but the population in southwest Asia, and to a lesser extent the population in east Africa, probably suffered severe climate effects. The population in west Africa, protected by mountains to the east, was not as seriously effected. Within a few thousand years India was repopulated from the east by proto-Australoids.
By 50,000 years ago the population that had remained in southwest Asia had evolved into proto-Caucasoids and began to expand: to the northwest up the Tigris-Euphrates valley to the Levant by 45,000 years ago; and to the northeast through Central Asia to the mammoth steppe of Siberia where they developed into the Ancient North Eurasians. From the Levant they expanded north into Anatolia, from there entering Europe through the Balkans and spreading the Aurignacian culture across southern Europe by 43,000 years ago. From the steppes of Siberia they moved westward into Europe, spreading the Gravettian culture, about 33,500 years ago. Shortly after this another Caucasoid group expanded from the Levant across North Africa. In this same time frame the population in Indochina and southern China had evolved into proto-Mongoloids and expanded northwards into the steppes of eastern Siberia, branching into southern and northern Mongoloid groups. Some of the northern proto-Mongoloids in eastern Siberia intermixed with Ancient North Eurasian Caucasoids and subsequently migrated east across the Beringia land bridge, from where they moved south into the Americas.
By 30,000 years ago the divergent evolutionary branching or dividing of the human species had produced five main lines or subspecies which are still extant: the Congoid of West and Central Africa; the Capoid of East and South Africa (later replaced in East Africa by the Congoid); the Australoid of India, Burma, Malaya, Indonesia, New Guinea and Australia; the Mongoloid of East Asia (later expanding to the southwest into Burma, Malaya and Indonesia, largely replacing the indigenous Australoids) and the Caucasoid of Europe, North Africa and West Asia. These subspecies branched or divided in turn into separate races, and these races branched in their turn into subraces, as part of the continuing process of divergent evolution.
Beginning about 20,000 years ago, when the global human
population was perhaps a million, the Last Glacial Maximum (LGM)
pushed the population of northern Europe south to refuge areas (refugia)
in southern France, northern Spain, the Balkans and Ukraine, while
the now fully-developed northern Mongoloid population in Siberia
was also forced south to eastern and southern China. Both
populations were greatly reduced in number during this period.
When the Last Glacial Maximum began to recede about 15,000 years
ago (13,000 B.C.) the survivors of these populations expanded
northward again from their refuge areas, with Scandinavia and
Britain being occupied about 11,000 years ago, by which time the
global human population had risen to perhaps 10 million.
Agriculture and the Neolithic (New Stone Age) period began about
12,000 years ago in southwest Asia and shortly after in China.
Prior to this all the populations of humanity had always been
"hunter-gatherers," living by hunting and gathering the fruits of
the natural vegetation, which could only support a low-density
population, with Caucasoid hunter-gatherers in Europe, North
Africa and West Asia (including the mammoth steppe of Siberia);
Australoid hunter-gatherers in India, southeast Asia, Indonesia,
New Guinea and Australia; Mongoloid hunter-gatherers in East Asia;
Congoid hunter-gatherers in West and Central Africa, and Capoid
hunter-gatherers in East and South Africa. Agriculture supported a
much higher population density then hunter-gathering, and so
enabled massive population growth which spurred geographic
expansion and the replacement of hunter-gatherer peoples by
Neolithic farmers in varying degrees. Over the course of many
generations the Mongoloid rice farmers of southern China expanded
southwards into southeast Asia and across Indonesia, mixing with,
assimilating and largely replacing the smaller aboriginal
populations of Australoid hunter-gatherers. Similarly, the
Caucasoid wheat farmers of southwest Asia expanded eastward into
Pakistan and northern India where they mixed with and partly
replaced the native Australoid hunter-gatherers, westward across
North Africa and northwest into Anatolia, and starting about 8,500
years ago (circa 6,500 BC) from Anatolia across Europe, mixing
with, assimilating and partly replacing the indigenous Caucasoid
hunter-gatherer populations. This expansion had two branches, the
first moving through the Balkans and up the Danube valley into
central and northern Europe, the other moving through the
Mediterranean to the Iberian peninsula and then north through
western Europe, reaching the British Isles about 6,000 years ago
(circa 4,000 BC), and is noted for creating megalithic structures
such as Stonehenge (circa 2,500 BC).
The last major demographic and genetic shift in the Caucasoid
region started about 5,200 years ago (circa 3,200 BC) with the
expansions of what is currently (2019) referred to as the Yamnaya
peoples of the Pontic-Caspian steppe, centered in what is now
Ukraine. The Yamna are also known as the Kurgan people,
with both terms derived from their custom of burying their dead in
pit graves (local word "yama" for pit) under mounds or tumuli of
earth (local word "kurgan" for mound or barrow). The
Yamna-Kurgans, largely descended from the Ancient North Eurasians,
were a semi-nomadic pastoral people who herded cattle and sheep on
the steppe and domesticated the horse for use in herding and war.
They were also the source and carriers of the Indo-European
languages which they spread with their conquests and genes. By
2,600 BC the peoples of the "Corded Ware" (named after the style
of their ceramic ware or pottery) aka "Battle-Axe" cultural area
or "horizon" across north-central and northeastern Europe were
genetically over 75 percent Yamna-Kurgan in ancestry, largely
replacing the earlier mixture of hunter-gatherer and Neolithic
farmer elements.
After 2,500 BC the predominantly Yamna-Kurgan elements of the
Corded Ware culture blended with the peoples of the expanding
"Bell Beaker" culture (also named after the style of their
pottery) of western and central Europe and with this culture
expanded into the British Isles, again largely replacing the
existing population.
To this day Yamna-Kurgan ancestry accounts for over 50 percent of
genetic ancestry in Scandinavia, Finland and the Baltic states, 48
percent in Scotland and 41 percent in England. It declines moving
south, to 38 percent in France, 28 percent in Tuscany (central
Italy), 23 percent in Spain, 20 percent in Greece and 5 percent in
Sardinia. Neolithic farmer ancestry tends to follow the opposite
pattern, declining moving north, from 88 percent in Sardinia to 76
percent in Spain, 72 percent in Tuscany, 51 percent in France, 43
percent in England, under 30 percent in Scotland and Norway, 18
percent in Lithuania and 12 percent in Estonia. The more varied
hunter-gatherer component (see below) is largest in the northeast
(e.g., Estonia at 37 percent, Lithuania 32 percent, Belarus and
Ukraine 28 percent) and the more remote areas of the northwest
(e.g., the Orkney islands at 27 percent and Scotland at 23
percent) where there was less Neolithic farmer penetration.
The European populations we know today were formed from the
mixture of these three Caucasoid ancestral components in varying
degrees combined with 5,000 years of subsequent continued
evolution in different environments with a significant degree of
reproductive isolation provided by geographic distance. The
phenotypic differences and subracial identities that characterize
the modern European populations were already recognizable and
described by the authors of antiquity (especially with regard to
the Keltic and Germanic peoples), indicating that the continuing
process of differentiation was already well-advanced at that time.
The above graphic includes all the hunter-gatherers in one
category called "Western European Hunter-Gatherer," but more
precise studies and graphics (see below) differentiate the
hunter-gatherer category into four separate groups: Western
Hunter-Gatherer (WHG) in Britain, France and the Iberian
peninsula; Scandinavian Hunter-Gatherer (SHG) in Scandinavia;
Eastern Hunter Gatherer (EHG) in eastern Europe; and Caucasus
Hunter-Gatherer (CHG) in the Caucasus mountain region. The
hunter-gatherers of Scandinavia and eastern Europe were partly
descended from Ancient North Eurasians (ANI) and had two genes for
light skin pigmentation which the Western Hunter-Gatherers (e.g.,
"Cheddar Man") lacked.
The above diagram (from the video "North Vs South Europe_ Early
Neolithic Farmers" on the Survive the Jive channel)
provides a visual representation of the genetic relationship
between the different ancestral Caucasoid populations in Europe
and the Middle East from about 12,000 BC to 2,000 BC, beginning
with the first Natufian farmers in the Levant (lower right), which
(moving toward the lower center) expanded into Anatolia and then
(circa 6,500 BC) into Europe, where the farmers largely replaced
the Western Hunter-Gatherers (WHG at lower left), to a lesser
extent the Scandinavian Hunter-Gatherers (SHG at center left), and
to a still lesser extent the Eastern Hunter-Gatherers (EHG at
upper left). In northern Europe this blended population was
largely replaced by Indo-European Yamnaya pastoralists (top
center) by 2,600 BC, providing the predominant ancestry of the
peoples of the Corded Ware culture. By the period of the mature
Bell Beaker culture in the Bronze Age circa 2,300-2,000 BC the
populations of Europe were a varied blend of Yamnaya,
Hunter-Gatherer and Neolithic farmer elements and have remained so
ever since.
The above diagram of genetic "clusters" (from the same video as
the previous diagram) provides a visual representation of the
relationship or relative genetic distance between the different
modern Caucasoid populations of North Europe (green), South Europe
(blue), the Middle East and North Africa or "MENA" (red and pink),
the Caucasus region (purple) and the several Jewish components
(yellow). The smaller or tighter the cluster the greater the
degree of genetic homogeneity in the category. The Ashkenazi
components of the Jewish cluster overlap with the South European
cluster, indicating a semi-European ancestry which is consistent
with studies indicating the Ashkenazim average 50-60 percent
Middle Eastern and 40-50 percent European ancestry. The positions
of several ancient populations are also projected onto the
diagram, with Ancient North Eurasians (a major component of
Yamnaya ancestry) at top center, Scandinavian hunter-gatherers
(also largely of Ancient North Eurasian ancestry) at center left,
and Western European hunter-gatherers (with no Ancient North
Eurasian ancestry) at lower left.
The modern races are often popularly defined and named (often inaccurately) by skin color, but as this system is based on only one genetic phenotypic difference, when hundreds are involved, it tends to distort the reality of race and racial differences. In the system of modern racial classification outlined below, based on classical phenotypic (non-genetic) physical anthropology, especially Carleton Coon and John Baker, the names assigned to the various subspecies and races are largely derived from geographical locations with which they are associated.

The diverse races of the human species outlined above all have
their own geographical territory that has historically been
exclusively their own, which may be referred to as their racial
homeland, and is closely identified with the race that inhabits
it. Between most of these exclusive homelands are clinal zones --
areas of contact between different racial territories. These
racial borderlands are frequently areas of interracial contact and
intermixture where adjacent races merge into one another, creating
racially mixed or hybridized populations of intermediate type
called racial clines. The Dravidic race of India, Bangladesh and
Sri Lanka, created by the intermixture of the local Caucasoid
(Indic or Nordindid) and Australoid (Veddoid) populations, and the
Aethiopid race of Ethiopia and Somalia, created by the
intermixture of the local Caucasoid (Mediterranid) and Congoid
races, are two very ancient racial clines which have stabilized
into distinct races of intermediate type. Racial clines of more
recent formation, where the racial blends are not yet stabilized,
include the populations of many Latin American and Caribbean
countries, which were created over the last 500 years by the
intermixture of various Caucasoid (mostly Mediterranid), Congoid
and Amerindian elements. The population of Mexico, for example, is
about 5% Caucasoid, 30% Amerindian and 65% Mestizo, the
Spanish term for persons of mixed Amerindian-Caucasoid ancestry.
(The same term is used in the Philippines for persons of mixed
Filipino-Caucasoid ancestry.) The multiracialization of the
populations of North America and, more recently, Europe, has begun
to transform them into racial clines. As discussed in other essays
on this site, this process of racial transformation will
eventually cause the effective extinction or nonexistence of the
European racial types in the affected areas unless adequate
preservationist measures are taken to prevent it.
What are the percentages of genetic differences between the human
races, indicating their relationships? Perhaps the best global
scale study to date (2019) on this subject is still that of
Masatoshi Nei and Arun K. Roychoudhury from Evolutionary
Relationships of Human Populations on a Global Scale (1993).
Subsequent studies, which have included increasing numbers of
alleles but have usually been regional rather than global in
scale, have been consistent with Nei and Roychoudhury's results.
The following table (Fig. 1 below) of estimates of genetic
differences between human populations is from their study.
The following table of percentages of genetic differences between
human populations presents the estimates for 19 populations from
the above table in an easier to read and understand format. The
human-chimpanzee genetic difference, giving the greatest degree of
difference from the commonly accepted range using the same
methodology, is added for context and comparison.
If one were to spatially visualize the first column of the above
scale, with a German standing at a distance of 20 feet from an
Englishman, a Finn would stand at a distance of 50 feet, an
Italian at 70 feet, a northern Indian at 200 feet, a Japanese at
610 feet, a North American Amerindian at 760 feet, a Nigerian at
1,330 feet, and a Chimpanzee at 16,000 feet. The greatest
percentage of genetic difference is .176% between Nigerians and
Australian Aborigines. This is 11% of the genetic difference of
1.6% between humans and chimpanzees, different biological Families
whose ancestral lines are believed to have separated about 5.5
million years ago. The .133% genetic difference between the
English and Nigerian populations is 8.3% as large as the genetic
difference between humans and chimpanzees. The .061% genetic
difference between the English and Japanese or Korean populations
is 3.8% as large as the genetic difference between humans and
chimpanzees. Seen in this context, these are very significant
genetic differences. It is also worth noting that for both the
English and the Japanese, representing Europeans and Northeast
Asians, the greatest percentage of genetic difference is with the
Nigerians, and that the degree of this difference, .133% for the
English and .149% for the Japanese, is very similar. By
comparison, the English and Japanese degree of difference from the
Australian Aborigine population, .122% for the English and .062%
for the Japanese, is very different, with the English-Australoid
difference twice as great as the Japanese-Australoid difference,
presumably explained by the more recent divergence of the
Mongoloid and Australoid branches and the extent of their common Denisovan
mixture (see above).
The phylogenetic tree below, presenting a visual
schematic of the genetic relationship between the different human
populations, is also from the 1993 study by Nei and Roychoudhury.
As seen in the above phylogenetic tree the major genetic
divisions or branches of human populations are Africans (A),
Caucasians (B), Greater Asians (C), Amerindians (D) and
Australopapuans (E). Genetic studies have consistently grouped the
populations of humanity into superclusters and clusters, or main
branches and sub-branches, that are consistent with the
traditional classification of racial divisions and subdivisions.
The Caucasian branch on the tree (B) has a main European
sub-branch (76) which includes the Lapps or Sami of the Arctic
region, then a separate sub-Arctic European sub-branch (75), then
a separate Northern European sub-branch (56) which has a northwest
European branch (92) represented by the English and German
samples.
