Revision summary
Adaptability is plasticity, acclimatisation and subsistence flexibility. Ecology is energy, season, pathogen and land, and it is not a neutral stage. Political economy is class, market, state and colonial history, as in Wolf and Mintz. The join is political ecology and the embodiment of inequality, as in Goodman and Leatherman. The household is the hinge of diet, labour and exposure. Poverty is not an adaptation.
Model answer
Introduction
Bio-cultural anthropology studies how bodies and environments make each other through culture. Political economy asks who owns the land, water and labour. The question wants the join: adaptation is never only a clever fit to climate. It is a fit to a climate already shaped by prices, stigma and the state.
Body
Three lenses, one field
- Adaptability: Humans adjust by acclimatisation, developmental plasticity and shifts in subsistence. Julian Steward’s cultural ecology, and later human biology of high altitude, heat and cold, sit here. Andean chest morphology and Tibetan responses to hypoxia are standard biological examples.
- Ecology: Energy, seasonality, pathogens and soils matter. Cultural ecology sometimes treated “the environment” as a neutral stage.
- Political economy: Production, class, colonial and post-colonial markets, and household labour. Eric Wolf in Europe and the People without History and Sidney Mintz on sugar showed that people do not adapt to nature in the abstract. They adapt to nature as already claimed.
How the join is made
Political ecology puts power inside the ecosystem. Deforestation, dams, slum heat islands and occupational dust are ecological facts with owners. Alan Goodman, Thomas Leatherman and other biocultural medical anthropologists treat nutrition, growth and blood pressure as biological outcomes of those conditions. Paul Farmer called the same process structural violence.
- Constraint versus strategy: A high-altitude chest or a seasonal hunger season can be adaptability. The same chest working in a mine, or hunger in a landless household, is political economy written as physiology.
- Embodiment of inequality: Growth failure, anaemia and reproductive outcomes track class, caste, tribe and gender. Biology is not the opposite of politics. It is one of politics’ archives.
- Household as hinge: Who eats last, who migrates, and who faces indoor smoke is the ecology of the hearth under kinship and wage.
A concrete Indian join is Adivasi nutrition near mines and plantations, or urban gig-workers in heatwaves: season and pathogen are real, but so are land loss, informal wages and weak housing. COVID-19 reverse migration made the same point: infection ecology met political economy on the highway.
Anthropological payoff
Pure adaptability talk can naturalise poverty as “they are adapted to scarcity”. Pure political-economy talk can forget pathogens, altitude and developmental windows. Bio-cultural work holds both. Plasticity is real, and so is the unequal distribution of stressors. Nutritional status is the same architecture in a health key.

Conclusion
Integrate the three by treating environment as political and the body as historical. Adaptability is the capacity. Political economy decides which bodies must use it, and how far. That is bio-cultural anthropology after the critique of cultural ecology’s innocent ecosystem.

Is this the same as cultural materialism?
It is a related ancestor in Marvin Harris, but this question wants power and inequality, not infrastructure as destiny. Prefer Wolf, political ecology and biocultural health.
-
What example joins all three lenses?
Stunting as seasonal ecology plus landlessness plus gendered serving of food. Adivasi health near mines is another.

What is acclimatization? Discuss adaptive responses to high altitude and cold climate
Concepts and methods of Ecological Anthropology: Bio-cultural Adaptations
Acclimatization is reversible adjustment within a lifetime. It is not the same as genetic adaptation, though they combine. Altitude responses are ventilation, heart rate, and later haematology. Tibetans and Andeans solve hypoxia by different mixes of physiology and genes. Cold responses are shivering, vasoconstriction, diet, and Arctic clothing.

Discuss the genetic and non-genetic factors in the bio-cultural adaptations of human beings to different environments.
Concepts and methods of Ecological Anthropology: Bio-cultural Adaptations
Genetic adaptations include malaria alleles, altitude genes, and lactase. Non-genetic adaptations are sweating, ventilation, and developmental shape. Culture—clothes, food, houses—does most polar and desert work. Farming and malaria show culture selecting genes. No environment is solved by DNA alone.

Immediate cold defence is skin constriction and shivering. Finger hunting reaction rewarms digits at a cost. Acclimatization can raise heat production and habituation. Bergmann and Allen rules are population trends. Technology and diet do most of the work in polar life.
