Hunter-Gatherers and Skin Color
- NOTOC**
Hunter-Gatherers and Skin Color
Human skin pigmentation is one of the most visible examples of biological variation, but research on ancient and living hunter-gatherer populations shows that its evolutionary history is far more complicated than a simple progression from dark to light skin. Ancient DNA, population genetics, archaeology, and studies of ultraviolet radiation indicate that hunter-gatherers living in different places and periods possessed a wide range of pigmentation-associated genetic variants.
There was therefore no single "hunter-gatherer skin color." Foragers lived across Africa, Europe, Asia, the Arctic, the Americas, and other environments for tens of thousands of years. Their populations had different ancestry histories and encountered different levels of ultraviolet radiation, climates, diets, and patterns of migration. These factors produced substantial regional and temporal diversity in pigmentation.
Ancient DNA has been particularly important because the appearance of prehistoric people cannot reliably be inferred from the appearance of people living in the same region today. Modern populations are often descended from multiple migrations and population replacements that occurred long after earlier hunter-gatherers lived there.
Skin Pigmentation as an Evolutionary Adaptation
Human pigmentation is primarily determined by the amount, type, distribution, and regulation of melanin in the skin. Numerous genes contribute to this process, making skin color a polygenic trait rather than a characteristic controlled by a single "skin-color gene."
One of the strongest environmental influences on the evolution of pigmentation has been ultraviolet radiation. In regions with intense ultraviolet exposure, greater melanin pigmentation provides protection against some harmful effects of ultraviolet radiation. At higher latitudes, where ultraviolet radiation is weaker and strongly seasonal, reduced pigmentation can facilitate ultraviolet-driven vitamin D production.
This relationship, however, is not mechanically determined by latitude. Diet, clothing, shelter, mobility, seasonal behavior, population history, and genetic variation can modify the selective pressures acting on pigmentation. Hunter-gatherers whose diets contained substantial quantities of vitamin-D-rich fish or marine mammals, for example, may have experienced different nutritional pressures from agricultural populations relying heavily on cereal crops.
Consequently, similar environments did not necessarily produce identical pigmentation, and similar skin colors evolved through partly different genetic pathways in different populations.
Ancient European Hunter-Gatherers
Ancient DNA has transformed scientific understanding of European hunter-gatherer pigmentation. Older reconstructions sometimes implicitly assumed that prehistoric Europeans resembled modern Europeans. Genomic evidence demonstrates that this assumption is unreliable.
One of the most influential discoveries came from La Braña in Spain. DNA from a roughly 7,000-year-old Mesolithic hunter-gatherer contained ancestral variants at important pigmentation loci while also carrying variants strongly associated with blue eyes. Researchers consequently reconstructed an unusual combination by present-day European standards: relatively dark skin pigmentation with light-colored eyes.
Cheddar Man, a Mesolithic individual who lived in Britain roughly 10,000 years ago, produced a broadly similar reconstruction. Genetic analysis indicated a high probability of relatively dark pigmentation together with blue or blue-green eyes. These findings attracted considerable public attention because they challenged the common assumption that the earliest postglacial inhabitants of western Europe necessarily had pale skin.
Other ancient individuals provide additional examples. DNA recovered from approximately 5,700-year-old chewed birch pitch in Denmark belonged to a woman with hunter-gatherer ancestry. Genetic phenotype prediction suggested dark skin, dark hair, and blue eyes.
These individuals should not be interpreted as proof that all European hunter-gatherers looked alike. Instead, they illustrate combinations of pigmentation traits that were present among some western and northern European foragers.
A European Pigmentation Mosaic
Larger ancient-DNA datasets show that European hunter-gatherer pigmentation formed a geographic mosaic.
Western European hunter-gatherers frequently retained ancestral variants at several important skin-pigmentation loci. Eastern hunter-gatherers generally possessed some light-pigmentation-associated variants at higher frequencies, while Scandinavian hunter-gatherers carried unusually high frequencies of several variants associated with lighter pigmentation.
Scandinavian genomes are especially important because they demonstrate that substantial pigmentation differentiation existed among hunter-gatherers themselves before agriculture became dominant. Populations reaching Scandinavia through different postglacial migration routes mixed with one another, producing genetic combinations distinct from those of many western European foragers.
The evidence therefore argues against describing Mesolithic Europeans collectively as either uniformly "dark-skinned" or uniformly "light-skinned." Pigmentation varied between populations and changed over time.
The Rise of Light-Pigmentation Alleles in Europe
Several genetic variants associated with lighter pigmentation became increasingly common in Europe during later prehistory. Among the most important are variants involving genes such as SLC24A5 and SLC45A2.
Ancient DNA indicates that these variants did not all become common simultaneously. Their frequencies changed over thousands of years through a combination of migration, admixture, and natural selection.
Early farmers arriving from Anatolia carried ancestry and pigmentation-associated variants different from those of many indigenous European hunter-gatherers. Later interactions between farmers and foragers redistributed these variants. Subsequent migrations, including population movements from the Eurasian steppe, altered European ancestry further.
Natural selection also changed allele frequencies within populations. Large ancient-genome datasets reveal strong selection at pigmentation loci during European prehistory, including substantial changes after agriculture had already spread.
Modern European pigmentation therefore represents the cumulative result of many prehistoric populations and evolutionary processes rather than the unchanged appearance of Europe's original hunter-gatherers.
African Hunter-Gatherers and Pigmentation Diversity
Africa contains the deepest human genetic diversity, and studies of African hunter-gatherer populations have substantially expanded scientific understanding of pigmentation evolution.
Populations with hunter-gatherer histories—including KhoeSan groups of southern Africa, Hadza and Sandawe populations of eastern Africa, and Central African rainforest hunter-gatherers—represent deeply divergent human lineages with complex histories of population separation and admixture.
Research among African populations demonstrates that pigmentation is controlled by many variants, some of which have very ancient evolutionary origins. Variants associated with both darker and lighter pigmentation are found within Africa, showing that human pigmentation diversity did not simply originate when people migrated out of Africa.
KhoeSan populations are particularly informative. Some southern African San populations have relatively lighter average pigmentation than many equatorial African populations. Genomic research indicates that this characteristic cannot be attributed to a single genetic cause. Multiple variants contribute, while later Eurasian-related ancestry introduced additional pigmentation alleles into some southern African populations.
Recent functional genomic studies have identified regulatory variation near genes including MITF, LEF1, and TRPS1 that may contribute to pigmentation differences among southern African populations.
African evidence therefore demonstrates that pigmentation diversity is ancient, polygenic, and geographically complex.
Migration, Admixture, and Population Replacement
Hunter-gatherer populations were never genetically static. Ancient genomes reveal repeated migrations, population expansions, contractions, admixture events, and replacements.
In Europe, different hunter-gatherer populations expanded after the Last Glacial Maximum and mixed with one another before the arrival of agriculture. Farmers subsequently entered Europe from Anatolia and mixed to varying degrees with indigenous foragers. Later steppe migrations further transformed the ancestry of European populations.
Similar complexity existed elsewhere. Ancient African genomes reveal long-standing interactions among eastern, central, western, and southern African populations. Eurasian-related ancestry entered parts of eastern and southern Africa before European colonialism. Asian hunter-gatherer populations also experienced repeated population movements and admixture, while the settlement of the Americas involved migrations and subsequent regional diversification.
Pigmentation-associated variants traveled with these migrating populations. As a result, the distribution of a pigmentation allele can reflect demographic history as well as adaptation to local environmental conditions.
Different Genetic Routes to Similar Skin Colors
One important finding from modern genetics is that similar pigmentation can evolve through different genetic mechanisms.
European and East Asian populations, for example, both underwent evolutionary changes associated with lighter average pigmentation, but many of the genetic variants involved differ between the regions. This is an example of convergent evolution: broadly similar traits can evolve independently under comparable environmental pressures.
African pigmentation provides another example of genetic complexity. Variants affecting pigmentation include ancient alleles found across deeply separated populations as well as regionally important variants with more recent histories.
Skin color therefore cannot be used as a simple proxy for genetic ancestry. People with similar pigmentation may have acquired it through different combinations of genetic variants, while closely related populations may differ substantially in pigmentation.
Eye, Hair, and Skin Color Evolved Separately
Ancient DNA also demonstrates that skin, eye, and hair pigmentation should not be treated as a single evolutionary package.
Genes such as HERC2 and OCA2 strongly influence eye color, while SLC24A5 and SLC45A2 have major effects on skin pigmentation in some populations. Because different pigmentation traits are partly controlled by different genetic systems, they can evolve at different rates.
The combination of relatively dark skin and blue eyes inferred for several western European hunter-gatherers illustrates this principle. Light eye pigmentation could become common within a population even while major light-skin-associated variants remained uncommon.
The familiar combinations of skin, eye, and hair colors found in modern populations therefore should not automatically be projected onto prehistoric populations.
Diet and the Transition to Agriculture
The transition from hunting and gathering to agriculture altered both human ancestry and the selective environment.
Hunter-gatherer diets varied enormously but could include wild plants, game, fish, shellfish, and other foods rich in micronutrients. Farming populations became increasingly dependent on domesticated plants and animals. In some regions, cereal-heavy diets may have reduced dietary sources of vitamin D compared with diets containing substantial fish or animal foods.
This has contributed to hypotheses that changes in diet strengthened selection favoring lighter pigmentation in some high-latitude agricultural populations. The evidence does not support a single explanation, however. Migration introduced important pigmentation variants, natural selection changed their frequencies, and diets and lifestyles continued to evolve.
The increase of light-pigmentation-associated alleles in Europe was therefore probably produced by interacting demographic, environmental, nutritional, and genetic processes.
Archaic Humans and Pigmentation
Pigmentation diversity predates modern hunter-gatherer populations.
Genetic studies of Neanderthals have identified variants affecting pigmentation, including a distinctive MC1R variant that may have produced reduced pigmentation in some individuals. Neanderthal-derived DNA surviving in modern Eurasian populations also includes variants affecting skin and hair biology.
Admixture between Homo sapiens and archaic populations therefore contributed additional genetic variation to later human populations. The evolutionary history of pigmentation is consequently part of a much older history involving both modern-human population differentiation and interbreeding with archaic humans.
Reconstructing Skin Color from Ancient DNA
Scientists generally reconstruct ancient pigmentation by identifying genetic variants associated with pigmentation in living populations and estimating the probable phenotype represented by the ancient genotype.
Systems developed for forensic genetics, including HIrisPlex-S, use combinations of genetic markers to estimate probabilities for eye, hair, and skin pigmentation. Ancient-DNA researchers have adapted such approaches to prehistoric genomes.
These reconstructions have important limitations. Ancient DNA is frequently degraded and incomplete, and low-coverage genomes may be missing relevant variants. Modern prediction models may also perform differently when applied to populations whose genetic combinations differ substantially from the modern populations used to develop the models.
New genotype-likelihood, imputation, and statistical methods are improving phenotype reconstruction from low-coverage ancient genomes. Large datasets now make it possible to analyze pigmentation at the population level rather than depending entirely on a few famous individuals.
For these reasons, reconstructions such as "dark," "intermediate," or "light" skin should be understood as scientific probability estimates rather than exact measurements of a person's appearance.
Skin Color and Modern Ideas of Race
The evolutionary history of hunter-gatherer pigmentation also illustrates why skin color is a poor basis for dividing humanity into discrete biological races.
Human populations have repeatedly migrated and mixed. Pigmentation evolved partly independently in different regions, and relatively small numbers of genes can produce conspicuous differences in appearance against a background of extensive shared ancestry.
Ancient Europeans could combine pigmentation traits that are less common among modern Europeans. African populations possess exceptionally high genetic and pigmentation diversity. Similar skin tones can arise through different genetic pathways, and neighboring populations can experience different evolutionary histories.
Skin color is therefore best understood as a variable human biological trait shaped by adaptation and population history rather than as a reliable boundary separating natural human categories.
A Dynamic Biocultural Trait
The accumulated evidence supports viewing human pigmentation as a dynamic biocultural adaptation.
Ultraviolet radiation created important selective pressures, but biological evolution occurred alongside cultural change. Clothing, shelter, diet, mobility, food production, and other behaviors altered how people interacted with their environments. Migration and admixture continually introduced new genetic variants into populations.
Hunter-gatherers are particularly valuable for studying this history because they occupied extraordinarily different environments before and during the enormous demographic changes associated with agriculture.
Rather than following a universal sequence from dark skin to light skin, human populations followed many different evolutionary trajectories.
Conclusion
Research on hunter-gatherers has overturned simple assumptions about the history of human skin color. Ancient DNA demonstrates that prehistoric populations were diverse and that modern appearances cannot simply be projected backward through time.
Some western European Mesolithic hunter-gatherers, including individuals represented by La Braña and Cheddar Man, have been reconstructed with relatively dark pigmentation and light eyes. Other hunter-gatherer populations, particularly in eastern and northern Europe, carried higher frequencies of variants associated with lighter pigmentation. African hunter-gatherer populations reveal an even deeper and more genetically complex history of pigmentation variation.
Over thousands of years, migration, admixture, natural selection, ultraviolet radiation, diet, population replacement, and cultural practices continually reshaped pigmentation-associated variation. Similar skin colors sometimes evolved through different genetic pathways, while genetically related populations could develop different pigmentation profiles.
The central lesson is therefore not that hunter-gatherers possessed a particular skin color. It is that human pigmentation has always been variable. Skin color is an evolving, polygenic characteristic whose history reflects the movement, adaptation, interaction, and diversity of human populations across the world.
