Revision summary
Bio-cultural anthropology joins bodies to diet, work, climate, and social rule. Lactase and sickle cell show culture as a selective environment. Washburn moved the field from racial types to process. Tibetan altitude and Inuit cold are teaching loops of physiology and practice. The hallmark is interaction, not genetic reduction.
Model answer
Introduction
Biological anthropology studies human variation, fossils, and primates. Its hallmark is that genes, bodies, and culture are not two separate files.
Body
What the approach is
- A bio-cultural view treats diet, workload, climate, and social rule as environments that shape growth, disease, and gene frequencies.
- Lactase persistence follows dairying. Sickle-cell follows farming and malaria. Culture here is a selective regime.
- Growth studies, from Tanner to Indian ICMR series, show how class and nutrition write themselves on stature.
Why it is the hallmark
- A purely anatomical race typology, or a purely cultural essay, misses the loop. Sherwood Washburn’s new physical anthropology asked for process, not types.
- High-altitude Tibetan and Andean work, and Inuit cold studies, are bio-cultural because behaviour, technology, and physiology meet.
- The approach does not reduce culture to genes. It refuses to study the body as if history were noise.

Conclusion
Biological anthropology is marked by the loop of organism and instituted life. That is the bio-cultural hallmark, not a slogan for genetic destiny.

-
Is bio-cultural the same as sociobiology?
No. Sociobiology often starts from gene strategy. Bio-cultural work starts from measurable bodies in social environments.
-
Does it ignore fossils?
Fossils are read with tools, diet, and climate. That is still a bio-cultural programme.

Animism and Deep Ecology
Religion
Tylor’s animism is belief in spiritual beings as the minimum of religion. Later work reads animism as relating to animals and places as persons. Naess’s Deep Ecology gives nature intrinsic worth beyond human use. The two meet as critiques of a dead, owned environment. They are not the same theory and must not revive Tylor’s ladder.

Marriage Regulations and Alliance Theory
Family
Marriage regulations forbid and prefer categories of spouse. Alliance theory reads marriage as exchange that constitutes society. Lévi-Strauss contrasted restricted and generalised exchange. Kachin and Dravidian systems illustrate positive alliance. Weiner’s Trobriand work shows women as givers, not only gifts.

Historical Particularism and Franz Boas
Historical particularism (Boas)
Historical particularism treats each culture as a unique historical product. Boas rejected Morgan–Tylor unilinear stages. Diffusion and invention must be proved, not assumed from similarity. Race, language, and culture are independent. Heirs used culture areas and texts; the risk is trait-listing.
