Revision summary
Erectus has a long low skull, torus, thick bone, and a larger brain than habilis. Nariokotome shows modern-like limb proportions. Range runs Africa, Dmanisi, Java, and China. Acheulian is typical in the west; East Asia often lacks classic bifaces. Narmada is the main Indian cranial candidate; tools are more widespread.
Model answer
Introduction
Homo erectus is the first hominin with a truly wide Old World range. It is a long-lived species of bigger brain, stout bone, and Acheulian tools.
Body
Salient characteristics
- Cranial capacity commonly about 800–1100 cc, above habilis, below later sapiens.
- A long, low vault, supraorbital torus, sagittal keeling in some Asian skulls, and a nuchal torus.
- Thick cranial bone, large face, and no chin. Postcrania, as in Nariokotome boy, show long legs and committed bipedalism.
- Reduced sexual canine contrast. Some specimens keep a robust body built for endurance walking.
- Culture: Acheulian handaxes in Africa and western Eurasia; East Asian assemblages often lack classic bifaces, a pattern still debated.
- Fire and home-base claims, as at Zhoukoudian and Gesher Benot Ya’aqov, are uneven but part of the species’ behavioural file.
Geographical distribution
- Africa: Koobi Fora, Olduvai (OH 9), Nariokotome (West Turkana), Bouri. African fossils are often labelled H. ergaster by splitters.
- Georgia: Dmanisi small-brained early emigrants, sometimes given their own names.
- Java: Trinil, Sangiran, Ngandong, Dubois’s founding pithecanthropus.
- China: Zhoukoudian (Peking Man), Lantian, Nanjing.
- Europe: Atapuerca and Ceprano sit near the erectus–heidelbergensis border.
- India: the Narmada (Hathnora) calvaria is often read as late erectus or archaic sapiens; Acheulian landscapes imply the grade even where bone is rare.
Time
- Roughly 1.8 million to a few hundred thousand years, later in Java. It is a grade with regional faces, not a single village.

Conclusion
Homo erectus combined a keeled, torused skull, large body, and Acheulian or flake kits. It ranged from East Africa through Dmanisi to Java and China, with Indian bone still thin but the tool map wide.

-
Is ergaster a different species?
Splitters say yes for African thinner-boned forms. Many textbooks keep one erectus grade.
-
Did erectus reach Europe as a named species?
Early Europeans are often called heidelbergensis. The boundary is contested.

Archaeological Anthropology.
Archaeological Anthropology.
Archaeological anthropology reads past culture from tools, bone, and settlement. Foote and Sankalia framed the Indian record. Dates come from layers and laboratories. Ethnoarchaeology links living discard to dead sites. The goal is process, not a museum of objects.

Society and Culture.
The Nature of Society
Society is organised relations of persons. Culture is Tylor’s learned whole of custom and knowledge. Kroeber stressed culture as superorganic; Radcliffe-Brown stressed structure. Nuer lineages show society; cattle idiom shows culture. Keep both in one ethnography.
