__NOTOC__
 
== Human Variation and Adaptation ==
 
Human populations display extensive biological and cultural variation, much of it resulting from the interaction of evolutionary history, migration, environment, natural selection, genetic drift, population mixing, development, and culture. Although all living humans belong to a single closely related species, populations that lived for many generations under different environmental conditions sometimes developed genetic or physiological traits that improved survival or reproduction in particular settings.
 
Modern genomics has greatly expanded the study of human adaptation. Scientists can compare genomes among populations, reconstruct past population movements, analyze ancient DNA, and identify changes in allele frequencies that may reflect natural selection. These studies show that human adaptation rarely follows a single pattern. Some adaptations involve a strongly selected genetic variant, while others involve many genes, developmental responses, cultural practices, or combinations of biological and cultural change.
 
Human variation therefore reflects both shared ancestry and repeated responses to local environments. Adaptation has occurred in response to altitude, ultraviolet radiation, pathogens, food sources, temperature, toxins, subsistence practices, and other environmental pressures.
 
=== Population Genomics and Human Adaptation ===
 
Population genomics examines genetic variation within and among populations and provides one of the principal tools for identifying human adaptation.
 
Researchers search genomes for patterns that differ from what would normally be expected from mutation, migration, population growth, population bottlenecks, and genetic drift. Strong natural selection can leave recognizable genomic signatures, although separating selection from demographic history is often difficult.
 
Early genome-wide studies identified numerous regions that appeared to have experienced recent positive selection. Large projects such as the 1000 Genomes Project and the Simons Genome Diversity Project subsequently provided much broader samples of human genetic diversity.
 
These studies have reinforced several important conclusions. Human genetic diversity is distributed largely within populations rather than in sharply separated biological groups. Populations nevertheless differ in the frequencies of many genetic variants because of ancestry, migration, drift, admixture, and local selection.
 
Africa contains especially deep human genetic diversity because modern humans originated there and African populations contain long and complex demographic histories. Greater representation of African and other historically understudied populations has revealed adaptive patterns that were difficult to detect using predominantly European genomic datasets.
 
Adaptation may involve several genetic processes. A new beneficial mutation can rapidly rise in frequency in what is sometimes called a selective sweep. Selection may instead act on variants already present in a population, on variants introduced through migration, or on many variants simultaneously. Consequently, human adaptation is often polygenic rather than dependent upon one gene.
 
=== Ancient DNA and the History of Natural Selection ===
 
Ancient DNA has transformed the study of human adaptation by allowing researchers to observe genetic variation at different points in the past rather than reconstructing history solely from living populations.
 
Ancient genomes show that allele frequencies associated with pigmentation, diet, immunity, metabolism, and other traits sometimes changed substantially over periods of only several thousand years.
 
These data also demonstrate that population replacement and migration can resemble natural selection if only present-day populations are examined. By comparing genomes through time, researchers can better distinguish changes caused by migration from changes caused by selection within populations.
 
Ancient DNA studies of Eurasia have documented major changes associated with the spread of farming, pastoralism, population migrations, changing diets, and infectious disease. They also demonstrate that many characteristics associated with modern populations developed gradually rather than being present in their current form throughout prehistory.
 
=== High-Altitude Adaptation ===
 
High-altitude populations provide some of the clearest examples of human adaptation. At high elevations, reduced atmospheric oxygen creates physiological stresses that can affect reproduction, growth, metabolism, and survival.
 
Populations of the Tibetan Plateau, Andes, and Ethiopian highlands have occupied high elevations for many generations, but they have not evolved identical responses.
 
Tibetan populations show strong evidence of selection involving genes associated with oxygen sensing, particularly EPAS1 and EGLN1. Tibetan highlanders generally maintain relatively low hemoglobin concentrations compared with some other high-altitude populations despite living under severe hypoxic conditions.
 
One of the most striking discoveries is that the adaptive Tibetan EPAS1 haplotype appears related to DNA inherited from Denisovans or a Denisovan-related population. This demonstrates that interbreeding with archaic humans supplied genetic variation that later became advantageous.
 
Andean highlanders often show different physiological characteristics, including relatively elevated hemoglobin concentrations. Ethiopian highlanders likewise exhibit genetic patterns that differ from both Tibetan and Andean populations.
 
The comparison illustrates convergent adaptation: separate populations exposed to similar environmental problems can evolve different biological solutions.
 
Adaptation must also be distinguished from acclimatization. Individuals moving temporarily to high altitude can undergo physiological changes without genetic evolution. Long-term population adaptation involves inherited characteristics shaped over generations.
 
=== Diet, Agriculture, and Metabolic Adaptation ===
 
Changes in diet have repeatedly influenced human evolution, particularly after the development of agriculture and animal domestication.
 
One of the best-known examples is lactase persistence. Most mammals reduce production of the enzyme lactase after weaning. In several human populations with long histories of dairying, however, genetic variants allowing continued digestion of lactose into adulthood became common.
 
European and African pastoral populations developed lactase persistence through partly different genetic variants. This represents convergent evolution and also provides a classic example of gene-culture coevolution. Cultural practices involving livestock and milk consumption changed the environment in which natural selection operated.
 
The selective advantage of lactase persistence may have involved more than simply obtaining calories from milk. Research suggests that famine, disease, contaminated water, and other crisis conditions may also have increased the survival advantage associated with digesting fresh milk.
 
Other dietary adaptations involve starch and fat metabolism.
 
Variation in the number of copies of the AMY1 salivary amylase gene has been studied in connection with starch consumption. Research indicates that changes at the amylase locus may have accompanied dietary transitions associated with agriculture and starch-rich diets.
 
Genes in the FADS region, which influence fatty-acid metabolism, also experienced selection associated with changing diets. The timing and direction of selection differed among populations and historical periods.
 
ADH1B variation in East Asia has similarly been studied in relation to alcohol metabolism and the development of agricultural societies.
 
These cases demonstrate that cultural innovations can create new ecological conditions that influence biological evolution.
 
=== Skin Pigmentation and Ultraviolet Radiation ===
 
Human skin pigmentation is one of the most visible forms of human biological variation and one of the clearest examples of adaptation to environmental conditions.
 
Melanin protects skin from ultraviolet radiation. Populations whose ancestors lived for long periods in regions of intense ultraviolet radiation generally evolved greater pigmentation, while populations living under lower ultraviolet conditions frequently evolved lighter pigmentation.
 
The evolution of pigmentation reflects competing biological demands. Dark pigmentation provides protection against ultraviolet damage and may help protect folate and other biologically important molecules. In environments with weaker ultraviolet radiation, however, lighter pigmentation can facilitate vitamin D production.
 
Genomic research demonstrates that skin color is polygenic. Many genes contribute to pigmentation, and similar pigmentation levels can evolve through different genetic pathways.
 
European and East Asian populations, for example, experienced substantial skin lightening through partly different genetic changes. African populations contain considerable pigmentation diversity and genetic variants associated with both darker and lighter pigmentation.
 
Genes and genomic regions associated with pigmentation variation include SLC24A5, SLC45A2, OCA2, MFSD12, DDB1, KITLG, TYR, and others.
 
Ancient DNA has also shown that the geographic distribution of pigmentation variants changed considerably during recent human history. Present-day pigmentation patterns therefore reflect selection, population migration, admixture, and cultural change rather than simple or permanent divisions among populations.
 
=== Pathogens and Immune Adaptation ===
 
Infectious diseases have been among the strongest selective pressures affecting human populations.
 
Malaria provides particularly important examples. Populations exposed to malaria for many generations contain relatively high frequencies of several genetic variants that reduce the likelihood of severe disease.
 
The sickle-cell allele is one of the best-known examples. Individuals carrying one copy of the allele can receive substantial protection against severe malaria, while individuals inheriting two copies can develop sickle cell disease. This creates an evolutionary tradeoff in which a variant associated with serious health consequences can remain common because it provides protection against another major threat.
 
Other malaria-related adaptations involve G6PD deficiency, the Duffy blood-group system, thalassemias, hemoglobin E, glycophorin variants such as the Dantu structural variant, and immune-system genes.
 
Pathogens have also influenced variation in HLA genes and many other components of human immunity.
 
Another example involves APOL1 variants found primarily among populations with ancestry in parts of Africa. Certain APOL1 variants provide protection against African trypanosomes but substantially increase susceptibility to kidney disease. This is another illustration of an evolutionary tradeoff in which an adaptation beneficial under one environmental pressure can produce harmful consequences under other conditions.
 
Ancient DNA provides additional evidence of pathogen-driven selection. Studies of individuals who lived before, during, and after major epidemics such as the Black Death suggest that severe infectious disease outbreaks could rapidly change frequencies of immune-related genetic variants.
 
=== Climate, Cold, and Human Body Form ===
 
Climate has influenced both human physiology and body form.
 
Humans living in cold environments can respond through behavior, clothing, shelter, fire, diet, physiological acclimatization, and genetic adaptation. These mechanisms frequently operate together.
 
Genomic studies have identified candidate adaptations involving cold perception, metabolism, fat utilization, thermogenesis, and other processes among Arctic and Siberian populations. Variants involving genes such as TRPM8 and CPT1A have been investigated in relation to cold environments and subsistence.
 
Human body proportions also show geographic patterns associated with climate. Populations from colder environments have often tended toward relatively compact bodies and shorter extremities, while populations from warmer environments frequently display relatively elongated limbs. These patterns are broadly consistent with thermoregulatory principles often described using Bergmann's and Allen's rules.
 
Climate may also influence nasal morphology. Because the nose helps warm and humidify inhaled air, variation in nasal shape has been investigated as an adaptation to temperature and humidity.
 
These relationships are statistical tendencies rather than rigid categories. Population history, nutrition, development, migration, and environment all contribute to human body form.
 
=== Adaptation to Extreme Environments ===
 
Human populations have occupied environments ranging from tropical rainforests and deserts to Arctic coastlines and marine environments. Some populations show biological adaptations associated with these unusual ecological conditions.
 
The Bajau of maritime Southeast Asia are well known for traditional breath-hold diving. Genetic and physiological research indicates that Bajau populations have unusually large spleens. Because the spleen can release oxygen-rich red blood cells during diving, this characteristic may increase available oxygen during repeated underwater activity.
 
Research on Korea's Haenyeo divers has similarly examined physiological adaptation associated with repeated diving and cold-water exposure.
 
Long-term exposure to naturally occurring arsenic provides another example. Indigenous populations living in parts of the Andes and Atacama Desert have experienced generations of exposure to arsenic-contaminated water. Genetic research has identified selection involving AS3MT and other genes associated with arsenic metabolism.
 
African rainforest hunter-gatherer populations provide another case. Several populations independently evolved relatively short adult stature. Genetic and ecological studies have investigated whether smaller body size provides advantages related to mobility, heat regulation, growth, nutrition, or life history in tropical rainforest environments.
 
Adaptation to desert environments has likewise been investigated through genomic studies of populations in regions such as the Arabian Peninsula.
 
=== Archaic Introgression and Adaptive Gene Flow ===
 
Modern humans interbred with Neanderthals, Denisovans, and possibly other archaic human populations. As a result, many living people carry small amounts of DNA inherited from these groups.
 
Most archaic genetic material either remained neutral or declined in frequency. Some archaic variants, however, appear to have provided advantages when modern humans entered unfamiliar environments.
 
This process is known as adaptive introgression.
 
The Denisovan-related EPAS1 haplotype in Tibetan populations is among the clearest examples. A genetic variant inherited through ancient interbreeding appears to have contributed substantially to adaptation to high-altitude hypoxia.
 
Archaic introgression has also been identified in genes involved in innate immunity. Neanderthal- or Denisovan-derived variants affecting OAS genes and Toll-like receptors appear to have altered immune responses in modern populations.
 
Other proposed examples involve metabolism, skin characteristics, circadian rhythms, and fat distribution. A deeply divergent haplotype involving TBX15/WARS2 is common in some Arctic and Indigenous American populations and has been investigated as another possible case of adaptive introgression.
 
Research in Oceania has revealed particularly complex Denisovan ancestry, including evidence for multiple admixture events.
 
These findings show that human adaptation did not depend exclusively on new mutations. Modern humans sometimes acquired useful genetic variation by interbreeding with populations already adapted to particular environments.
 
=== Culture, Niche Construction, and Gene-Culture Coevolution ===
 
Humans differ from most species in the scale at which culture alters environments and creates new selective pressures.
 
Humans build shelters, control fire, produce clothing, cultivate plants, domesticate animals, store food, modify landscapes, develop medicines, and transmit knowledge across generations. These cultural adaptations allow people to survive environmental challenges much more rapidly than genetic evolution alone could permit.
 
Culture can also change biological evolution.
 
This interaction is known as gene-culture coevolution. Lactase persistence provides a classic example. Once populations developed dairying traditions, adults capable of digesting lactose could gain nutritional or survival advantages. Cultural behavior therefore created a selective environment favoring particular genetic variants.
 
Agriculture produced many additional evolutionary pressures. Permanent settlements and larger populations increased exposure to infectious disease. Agricultural diets altered nutrition. Irrigation and land clearing sometimes increased mosquito habitat and malaria exposure. Domesticated plants and animals changed food availability and metabolism.
 
Niche-construction theory describes these processes more broadly. Organisms do not simply adapt to environments; they also modify those environments. Humans are unusually powerful niche constructors because cultural knowledge allows environmental modifications to accumulate across generations.
 
=== Adaptation, Plasticity, and Acclimatization ===
 
Not every difference among human populations is genetic, and not every response to an environment represents evolutionary adaptation.
 
Human biology is highly plastic. Nutrition, childhood development, physical activity, disease exposure, temperature, altitude, and many other environmental factors can influence an individual's physiology and appearance.
 
Acclimatization occurs when individuals develop reversible physiological responses to environmental conditions. People moving to high altitude, for example, can increase breathing rates and alter blood physiology without inheriting genetic adaptations.
 
Developmental plasticity can produce longer-lasting responses when environmental conditions experienced during childhood influence adult physiology.
 
Cultural adaptation provides another mechanism. Clothing, shelter, cooking, food storage, agriculture, medicine, and technology can reduce environmental pressures without genetic change.
 
Consequently, observed human variation may result from genes, developmental environments, cultural practices, or interactions among all three.
 
=== Human Diversity Is Continuous and Dynamic ===
 
Population genetics demonstrates that human variation does not divide humanity into a small number of sharply bounded biological types.
 
Human populations have repeatedly migrated, mixed, separated, and reconnected. Genetic variation usually changes gradually across geography, while individual traits can follow different geographic patterns.
 
A population may therefore share ancestry or adaptive variants with several neighboring or historically connected populations. Genetic boundaries rarely correspond neatly with cultural, linguistic, national, or socially defined racial categories.
 
Adaptations are also specific to environmental circumstances. A trait that provides an advantage in one environment can be neutral or harmful in another. The health consequences associated with sickle-cell, APOL1, and some metabolic variants illustrate this principle.
 
Human biological diversity is therefore best understood as the continually changing result of ancestry, migration, mutation, natural selection, genetic drift, admixture, development, environment, and culture.
 
=== Conclusion ===
 
Human variation reflects a long history of movement into diverse environments and repeated adaptation to new ecological and cultural conditions. Genomic studies, physiological research, anthropology, and ancient DNA now provide detailed evidence of how human populations responded to altitude, ultraviolet radiation, temperature, pathogens, toxins, changing diets, agriculture, and other selective pressures.
 
Some adaptations arose through new mutations, while others involved selection on existing genetic variation or genes acquired through migration and archaic introgression. Similar environments sometimes produced different genetic solutions, as demonstrated by high-altitude populations in Tibet, the Andes, and Ethiopia. Other adaptations, such as lactase persistence, demonstrate how cultural behavior can reshape biological evolution.
 
At the same time, genetics represents only one component of human adaptability. Physiological plasticity, acclimatization, social learning, technology, and culture allow humans to respond rapidly to environmental challenges.
 
The study of human variation therefore reveals both biological diversity and profound common ancestry. Human populations are not fixed or isolated categories but interconnected populations whose characteristics have continually changed through migration, adaptation, cultural innovation, and environmental change.
