Key Anthropology Diagrams Breakdown

• 1. Human Evolution & Primatology: Comparative skull diagrams showing sagittal crest reduction, prognathism reduction, and cranial capacity expansion from Australopithecus to Homo sapiens.
• 2. Kinship & Marriage Diagrams: Standard genealogical symbols ($\triangle$ for male, $\bigcirc$ for female, $=$ for marriage) depicting parallel-cousin vs cross-cousin marriage rules and lineage alliance theories.
• 3. Prehistoric Cultural Chronology: Glacial and interglacial cycles paired with tool culture typologies (Oldowan $\rightarrow$ Acheulian $\rightarrow$ Mousterian $\rightarrow$ Upper Palaeolithic blade tools).
• 4. Indian Tribal & Social Systems (Paper II): Spatial distribution maps of Indian tribes (PVTGs), dominant caste interaction models, and sacred complex flowcharts (L.P. Vidyarthi).

4 Rules for Drawing High-Scoring Anthropology Diagrams

1. Keep Execution Under 90 Seconds: Use simple geometric lines, stick figures, and arrows rather than complex artistic drawings.
2. Always Add Clear Labels: Unlabeled diagrams carry zero value. Label anatomical or structural features clearly on the right side.
3. Enclose in a Neat Box: Draw a clean border around every schematic and give it an explicit title (e.g., "Figure 1.1: Bipedal Adaptations in Pelvis").
4. Reference in Main Text: Mention your diagram within your answer body (e.g., "As illustrated in Figure 1...") to maintain structural flow.
